Australian Weather

Today, 1:34AM UTC

A vast part of the continent will see much warmer temperatures than average for mid-autumn throughout the working week, as a broad area of high pressure dominates Australia’s weather pattern. The main exception is the southwest corner of Western Australia, where a trough has generated showers overnight, while a cold front will arrive on Thursday. That cold front will slowly push east, however it won’t impact the eastern states until the weekend, with significantly above-average maximum temperatures for this time of year at most locations from Tuesday through to at least Friday. Let’s break down the situation state by state, moving from west to east. Western Australia Perth had a wet Monday afternoon, with 8mm in the gauge in the 24 hours to 9am Tuesday. That rain should mostly clear this Tuesday, however a coolish maximum of 19°C is expected as a feed of high cloud from the northwest keeps a lid on warming. Temperatures will rise into the low twenties on Wednesday and Thursday ahead of the cold front due later on Thursday night.

Northern Territory It will be business as usual for this time of year in Darwin, with a dry spell to cap off the last few days of the official 2025/2026 Top End wet season. Darwin can expect maximums around 33°C all week, which is close to the average April maximum of 32.8°C.  Alice Springs can expect maximums close to the April average of 28.4°C all week, although the mercury should rise to around 31°C on Saturday, May 2. That will be around eight degrees above the average May maximum of 23.1°C. South Australia Adelaide slightly exceeded its average March rainfall and is within a few millimetres of its average April rainfall after a desperately dry summer, but rain is still very much needed in the SA capital. The good news is a wet spell could arrive with much cooler air this weekend. Before that, expect a dry, very warm week for late April. Adelaide’s average April maximum is 22.2°C while its average May maximum is 18.6°C, but maximums will be around 28°C or 29°C from Wednesday through to Saturday. Most other parts of South Australia will also be unseasonably warm for most of the working week.

Victoria Another warm week is in store for Melbourne and most of Victoria as the high pressure system centred over southeastern Australia drags warm air southwards from the interior of the continent. Melbourne can expect maximums in the mid-twenties from this Tuesday through to Sunday, in a pattern similar to last week, when Melbourne saw a run of six days when maximums were between 3 and 6 degrees above the average April maximum of 20.4°C. If Melbourne reaches its forecast maximum of 27°C this Friday, May 1, that would be just over 10 degrees above its average May maximum of 16.8°C.

Mostly dry conditions should persist until the weekend, with maximums around 24°C or 25°C. The average April maximum is 22.6°C. Canberra will continue its recent pattern of cool nights with minimums of 5°C or lower, while days rise to 22°C or 23°C, which is a degree or two warmer than the average April maximum of 21.0°C.  By this Friday, May 1, some locations in western NSW could see May warmth records threatened. For example, the small town of Ivanhoe has a May high temperature record of 29.2°C, with a high of 29°C forecast for both Friday and Saturday.  Tasmania After a cooler start to the week than the mainland capitals with maximums in the teens on Tuesday and Wednesday, Hobart will have a four-day warm spell with maximums between 23°C and 25°C from Thursday through to Sunday. Given that Hobart’s average May maximum is just 14.6°C, Saturday could be more than 10 degrees above average. The rest of Tasmania also looks to be in for some unseasonable warmth.
