Temperature and fire danger soaring this weekend

Extreme fire danger is expected in four states this weekend – including one area with catastrophic fire danger – as a brief burst of heat affects South Australia, Victoria, Queensland and New South Wales.

The heat will impact SA and Vic first, with temps soaring on Saturday.

  • Adelaide is heading for 37°C on Saturday and Melbourne is going for 34°C.
  • if those maximums are reached, they would both be the hottest days so far in spring 2024.

Meanwhile temps in northeastern SA will top 40°C, while the northwest corner of Victoria will nudge the 40-degree mark.

Even places like Warrnambool on Victoria’s southern coastline should reach 35°C on Saturday. That would be more than eight degrees above the city’s hottest temp recorded so far in spring 2024.

Gusty winds will also accompany the hot temps as northerlies strengthen ahead of an approaching cold front, and that’s why the fire danger is elevated in both SA and Victoria on Saturday.

As you can see, the highest fire danger in the country for Saturday is the catastrophic rating in the Eastern Eyre Peninsula forecast district.

That reflects not just the classic hot and windy conditions which so often fuel bushfires, but the dry weather which has prevailed for virtually all of 2024 – making the landscape highly prone to burning.

As the chart below shows, severe rain deficits have been experienced this year in most of southern and eastern SA, and also in large parts of Victoria. The chart includes data from January to the end of October, and the pattern has continued into the first half of November.

To cite just one example of a location which is much drier than usual, let’s take the city of Whyalla (population approx. 22,000) on the eastern coastline of the Eyre Peninsula – in the region where the fire danger is rated catastrophic on Saturday.

Whyalla has a fairly arid climate at the best of times, but to date this year, it has received just 118mm of rain, which is less than half what would be expected to his point.

Image: The rain graph thus far for Whyalla in 2024 makes for pretty grim viewing.

The good news for residents of Adelaide and other places that will cop Saturday’s hot blast is that a cool change is coming. It should arrive in Adelaide in the later afternoon, with temps dropping from the high 30s down towards 20°C by 7pm.

The not-so-great news is that the cool change won’t have much rain coming along for the ride, with only a few millimetres at best expected for Adelaide into Sunday.

The heat spreads east on Sunday and this is reflected in Sunday’s fire map, with a few orange areas of extreme danger spreading into NSW.
