Take 2: Climate Diary of an Australian heatwave - January 2019

Round two for extreme heat roasting of Australia this summer.

The first heatwave round ocurred over the Christmas New Year period for which I did a daily climate blog. I followed this up with some simple analysis of the Maximum temperatures for capital cities and a number of regional towns. A further article looked at Mapping the heat trend in Australia's capital cities for 2018 and future projections.

While Sydney's eastern suburbs temperatures will be in the low 30s in the coming week, residents of Penrith and Richmond in Western #Sydney will swelter through four or five days above 40C says Dean Narramore a meteorologist with the Bureau of Meteorology.

The heatwave will impact large regions of inland Australia with lesser impact of perhaps some extreme heat days for coastal cities and towns. Major international sporting events such as the Australian Tennis Open in Melbourne and the Tour Down Under cycling event in South Australia will see their extreme heat policies implemented.

“Particularly northern South Australia, they’re looking at maybe five days in a row above 45 and normally they might only get five or 10 a year,” meteorologist Dean Narramore said on Sunday, according to The Guardian report.

It is well past time to take rapid action on climate, to reduce emissions and set ambituous targets that are our fair share of the Paris Agreement climate goals to keep global temperatures well below 2 degrees celcius and strive to meet a 1.5C target.

Heatwave Forewarning

Bureau of Meteorology explainer: "Like previous heatwaves over the south-east this summer, hot air will move down from the Pilbara in Western Australia, where it has been sitting quite stagnant over an extended period of time. The town of Marble Bar has now recorded 22 consecutive days above 40 degrees, including the highest temperature anywhere in Australia for 2018, reaching 49.3 degrees on December 27. Marble Bar ended the month with an average maximum temperature of 44.1 – a new national record for December." Read more



Algal Blooms in the Darling River and Menindee Lakes?


The draining of the Menindee lakes twice in 4 years by the NSW government and the Murray Darling Basin Authority has caused immense damage to the local ecosystem and it's resilience to withstand drought conditions.

The extreme heat in the coming week will likely dry up the last of the water in the Menindee Lakes in western NSW, near where up to a million fish suffered a catastrophic die-off due to low water levels, and an algal bloom die-off due to sudden temperature drop causing oxygen levels to plummet.

Heatwave to affect Tour Down Under Cycling event

The Tour Down Under likely to use a heat protocol, with at least one stage shortened this week. The Tour Down Under is conducted in Adelaide and surrounding hinterland. - SMH.

Race director Mike Turtur confirmed at a Sunday press conference that the race heat policy would be implemented with Wednesday's stage from suburban Norwood to Angaston in the Barossa to be cut by 26.9km, reducing the distance to 122km. The first stage on Tuesday from North Adelaide to Port is already a shorter race at 132km.

The temperature is forecast for Tuesday and Wednesday to hit 40-plus degrees for the first two stages, followed by a cool change to reduce temperatures the rest of the week.

"The safety and welfare of the riders, spectators and everyone involved with the race is always our primary concern," Turtur said in a statement. "We consulted with rider representative Adam Hansen, team director representative Matthew White and with our chief commissaire, and all parties have agreed it would be sensible to shorten the stage."

Bushfire warnings might also affect the race. Race director Michael Turtur told the Sydney Morning Herald, "Everyone needs to understand - if there was a catastrophic rating for any region, then the race cannot enter that region," he said. "We need to also bear that in mind, but that will be considered when and if that happens - it's one of those things we can't control. But certainly we have all the necessary protocols in place to deal with it." -

Sydney forecast for record breaking extreme heat conditions
Bureau of Meteorology Duty Forecaster Rob Taggart said the Bureau has declared a "severe" heatwave for the Sydney basin, with Western Sydney expected to see "extreme" heatwave levels. "There is a high-pressure system forming over the Tasman sea, and at the same time there is an inland trough coming from Central Australia," he said. "The system is basically not allowing cold fronts to come through and the trough is directing the hot air mass."

Due to higher humidity levels this heatwave is expected to be worse than the Christmas/ New Year heatwave according to Mr Taggart.

"Until we get to Saturday, it will really get bad in terms of humidity with particularly horrid, muggy days expected," he said. "During the Christmas period we had a dry heatwave, but this time we are getting light easterly winds off the ocean which makes it feel a lot worse," he told the Sydney Morning Herald: 'Horrid, muggy days': Sydney to swelter through record-breaking heatwave.

Horse Racing meetings cancelled
High temperatures of above 40C forecast in the Yarra Valley caused the cancellation of a horse racing meeting scheduled for Tuesday, according to Racenet. The Corowa race meeting on Tuesday has also been postponed due to the heat. The town of Corowa near the Murray river on the NSW/Victorian border has maximum temperatures forecast for Tuesday 45C, Wednesday 46C, Thursday 43C, and Friday 44C, before a change to drop maximum temperatures to around 30C on Saturday.

Heat to kick off Tamworth Country Music Festival
Tamworth has four 40C days lined up this week, with the Tamworth Country Music Festival due to kick off on Friday 18 January in the 40C heat. Forecast maximum temperatures for Tamworth are Tuesday 39C, Wednesday 42C, Thursday 42C, Friday 41C, Saturday 40C, followed by a slight drop in temperature for Sunday 35C, and Monday 33C. See Northern Daily Leader: Tamworth Country Music Festival weather forecast: extreme heat on the way

While we are talking about Tamworth, 2018 was the hottest year on record in Tamworth, according to a Weatherzone meteorologist who did the calculations for the Northern Leader..

Weatherzone senior meteorologist Brett Dutschke told The Leader: “Temperature records go back 62 years, and 2018 will probably beat 2014 as the hottest on record,” Mr Dutschke said. “That is combining nights’ and days’ average temperatures.”

The average maximum daytime temperature for Tamworth throughout the entire year was 26.7 degrees. The figure is a staggering 1.9 degrees above the long-term average of 24.8 degrees. Nights in Tamworth got down to an average of 10.1 degrees, only 0.3 degrees higher than the norm.

These figures combined to make the 2018 overall average temperature in Tamworth 18.4 degrees; the highest on record for the city and 1.1 degrees greater than the 62-year mean. The stats spell out a sweltering year for the city, which saw records broken even in the colder seasons.

“July’s days were almost 2.5 degrees above the normal,” Mr Dutschke said. “So July’s days were the warmest in at least 20 years. October nights were the warmest in at least 20 years and they were 2 degrees above the norm.”

Moree: First 40-degree heatwave of 2019: Moree set for four days above 40 degrees as weather heats up - Moree Champion. The forecast expects 40 degrees for Tuesday, 41C for Tuesday and Wednesday, 40C for Thursday and Friday, dropping to 39C for Saturday and 37C Sunday.

Western Sydney to Swelter while many parts of regional NSW expecting 45 degree temperatures
Parts of regional NSW to hit extreme temperatures with Sydney not spared - Sydney Morning Herald
"Even parts of the Snowy Mountains at Bombala and Cooma are likely to be very hot," Weatherzone senior meteorologist Jacob Cronje said.

Bombala will experience Maximum temperatures in the mid to high 30s this week, while Cooma will experience maximum temperatures of 37 and 38 degrees.

The hottest part of NSW is likely to be the Riverina:
  • Hay expected to reach 47 degrees on Tuesday and Wednesday, and 46 degrees on Thursday and Frday before dropping to 31 on Saturday.
  • Griffith is expecting 45 degrees on Tuesday, 47C on Wednesday, 46C on Thursday, 45C on Friday, before dropping to 32 on Saturday.
  • Wagga Wagga is expecting 44C on Tuesday, 45 on Wednesday, 44C on Thursday and Friday, before dropping to 31 on Saturday.
  • Narrandera is expecting 45 degrees on Tuesday, 46C on Wednesday and Thursday, 45C on Friday, and dropping to 30C on Saturday.

On the NSW central west slopes:
  • Dubbo is forecast to reach 43 degrees on Tuesday, 45C on Wednesday and Thursday, 44C on Friday, 41C on Saturday, before a slight drop to 35C on Sunday.
  • Parkes forecast is for 42 degrees on Tuesday, 44C on Wednesday, Thursday and Friday, with a slight drop to 36C for Saturday and 32C on Sunday.
  • Condobolin is expecting 45 degrees on Tuesday, 46C Wednesday, 47C Thursday, 46C Friday, before dropping to 34C on Saturday and Sunday.
  • Cowra is expecting 42C on Tuesday, 44C on Wednesday Thursday and Friday, before dropping to 36C on Saturday and 33C on Sunday.

The Town of Walgett, near the dried up junction of the Barwon and Namoi rivers where once paddle steamers used to navigate to, with salty bore water that exceeds National water guidelines, is trucking in drinking water. During the Christmas New Year heatwave a lightning strike hit the bore water pumping station which meant town water was turned off producing a water crisis while emergency repairs were made. The forecast this week is for 42C on Tuesday, 45C on Wednesday, 44C on Thursday, 43C on Friday, 42C on Saturday, 41C on Sunday, and 38C on Monday.

Suburban development model needs to change to anticipate urban heat island amplifying extreme heat

At the end of the ABC News article the need to change our residential development model quoting from Urban heat and ecosystem scientist at Western Sydney University, Dr Sebastian Pfautsch. He said that Sydney needed to prepare for a future of more heatwaves that were longer lasting and more intense. He regularly records urban heat island differences of up to 8C in new developments compared to nearby bush land.

"At the moment we're seeing developments for lot sizes that don't even allow to have trees anymore around your house because … there's no space left for trees that could actually help cooling the entire area," he said.

"One thing that we already see is that people become more isolated because there is less and less outdoor life particularly during summer — it's just too hot."

Continuously using air-conditioning on large homes, the use of black roofs and black bitumen on roads also prevents surfaces from cooling down.

Dr Pfautsch said local councils and governments needed to start implementing new strategies to create a "model suburb, where people can actually go and experience how it would feel if you have cool pavement, if you have green streets, everything is tree lined, if you have passive cooling in your house, if you have double glazed windows".

"All of these things I think would be much easier to convey to the public once you can experience them, at the moment I think we are lacking that."

Northern Victoria forecast extreme temperatures are likely to run till the weekend when temperatures will drop slightly:
  • Mildura: 46C degrees Tuesday, 46C on Wednesday, 45C Thursday, 39C Friday, 31C Saturday, 33C Sunday.

Fish Die-offs, algal blooms, drought and water mismanagement

NSW Primary Industries Minister Niall Blair revealed the latest fish die-off has occurred at Lake Hume on the NSW Victorian border with up to 1800 fish dead, although the cause is still being investigated. Lake Hume is controlled by the Murray Darling Basin Authority and is currently 30 per cent full.

Other recent fish die-off events that Mr Blair listed include outside Port Macquarie on Friday and yesterday at Lake Burrendong near Dubbo, as well as the much publicised massive fish deaths due to an algal bloom along the Darling River near the Menindee Lakes.

Estimates of fruit losses due to the heat range up to 30 percent of the crop this season. Stone fruit grower Dino Cerrachi says "There will be quite a lot of damage from direct sunlight, especially on the north-western side of the trees, or any exposed areas at the wrong time of that sun position. Basically, it just sort of cooks that side or that part of the fruit that has the direct sunlight for a length of time and it gives you an impression that it is soft, but it has actually gone jammy from being cooked."

The town of Menindee on the Darling River on Wednesday reached 47.6C, the third day in a row of reaching 47 degrees, and six straight days above 40 degree maximum temperatures. Thursday was forecast to hit 48C and back to 43C on Friday.

The town has had ten days in total above 40C to 16th January, when the long term mean for January is 5 days above 40C.

Mildura, Victoria:
MILDURA has already recorded 45C+ temperatures on two consecutive days: with temperatures on Tuesday 45.8C, and Wednesday 45.7C, with a Bureau of Meteorology forecast of 45C on Thursday.

According to the Sunraysia Daily, "since the town’s weather station moved to Mildura Airport in 1949, only twice – in 2004 and 2017 – has there been two straight days reaching 45C."

In 1939 at the old Mildura Post Office weather station in the town centre there were four consecutive days of 45C temperatures recorded.

For Mildura the mean number of days exceeding 40C in January is 2.7, and in 2019 so far (16th January) the town has already experienced 6 days above this temperature.

The temperature is forecast to drop slightly to 39C on Friday and further to 33C and 35C on the weekend, before rising again for 40 degree temperatures next week. - Sunraysia Daily - Mildura set to sweat through third straight 45C day

Queensland: persistence of heat records broken
In north western Queensland its not so much the intensity (although it is very hot), but the length and persistence of the heat. Climate change is making it hotter for longer. Check out Camooweal and Cluncurry in the north west of Queensland.

Camooweal has had 32 consecutive days above 40°C. The mean number of days for this towm for January ≥ 40 °C is 8.3. Up to 17 days this month over 40°C with nearly half a month still to go. The all time heat record for Camooweal is 46.6 on 23 Dec 1990. In the current run of maximum temperatures the top was 44.3C on 10 January.

Cloncurry has also recorded 32 consecutive days with max temps equal to or above 40°C. The Mean number of days ≥ 40 °C for Cloncurry is 6.8, well exceeded being now in the 17th day of the #heatwave. The all time heat record at Cloncurry is 46.9C set 1 Dec 2006. In the current run of maximum temperatures the top was 46.1C on 21 December.

Heatwave conditions: mandatory graded temperature threshold needed for certain outside work

Good to see the work of Dr Liz Hanna and other health professionals raising heat health and work issues. ABC News - Heatwave conditions could be fatal for outdoor workers if temperature cut-off not introduced, expert says

Dr Liz Hanna from the Australian National University said the legal obligations for employers to send their workers home in hot weather varied between jurisdictions and were often poorly enforced.

Some health and safety guidelines — as well as certain construction unions — required outdoor business owners to send their staff home when the temperature reached 37 degrees Celsius.

The CFMEU's ACT branch has this policy in place.

Dr Hanna admitted that the reality of a functioning society meant that not all work could simply stop at a certain temperature, but through her research came up with a suggestion for non-essential work.

Dr Hanna studied outdoor workers from all over Australia to see at what point heat-related illness affected them, and in turn has called for a mandatory graded temperature threshold for certain construction jobs.

She said the "graded scale" would consider heat, humidity, apparent temperature and the physical intensity of work, among other factors.

Bendigo get some good reporting on climate trend
"Bendigo used to experience fewer than one January day of above 40 degrees on average before 1991, but has sweated through five so far just 18 days into the month." The srticle quotes Bureau of Meteorologist Dr Trewin that heatwaves are becoming more frequent in Bendigo, as with the rest of Australia.

“Particularly in inland south east Australia we’ve seen a sharp increase in the number of hot days,” Dr Trewin said. “We see a substantial long term warming trend through Australia as we do globally. Australia has warmed by over a degree since 1910. With higher average temperatures you’d expect to see more heat extremes and that’s what we are seeing.”

"But along with that natural variability there is the background of climate change, and climate science telling us when it is hot, its likely to be hotter, and hotter for longer as well. So, yes, heatwaves, but with climate change they become more extreme."

"For pretty much most locations in the southern part of Australia, the heatwave is over,” said the Bureau of Meteorology meteorologist Dean Narramore. “So it should be a much cooler weekend for many areas, but then we’ll start seeing the heat return at least in Adelaide as we move into Monday, back into the high 30s."

"The rest of South Australia will be much much hotter, getting into the mid 40s probably from around Tuesday.” Read more at The Guardian Great Australian heatwave takes a breather – only to return again soon
