Hobart has recorded its hottest May day in 144 years of records, exceeding the old record of 25.7°C by well over a degree, on a day when May heat records were broken in four states. By far the most May heat records were broken in Tasmanian and Victoria this Friday, May 1, 2026, with South Australia and New South Wales also chiming in with a smattering of record highs. Tasmanian May heat records broken At 3:02pm Hobart hit 26.9°C. That was more than 12 degrees above the Tasmanian capital’s average May maximum of 14.6°C. Tasmania’s second city also broke records, with a reading of 24.3°C at 1:38pm at Launceston’s Ti Tree Bend weather station. The previous May record was 22.9°C. Overall, at least 20 Tasmanian weather stations in 10 of the state’s 11 official BoM forecast districts broke May records for either maximum or minimum temperatures this Friday. One of the more remarkable readings was at the tiny Central Plateau town of Liawenee, which is famous for its frigid overnight temperatures. Indeed, it holds the record for the state’s coldest recorded temperature of -14.2°C. Last night, Liawenee only dipped to 9.9°C. Its previous warmest May minimum was 9.0°C.

Victorian May heat records broken At least 20 Victorian weather stations have also registered heat records for May this Friday, including: Avalon on Melbourne’s western outskirts hit 29.3°C at 1:02pm. The old record was 28.0°C. The southwest Victorian city of Warrnambool reached 28.3°C at 1:23pm. The old May record was 27.9°C. Several weather stations within the Melbourne metropolitan area broke records, including Moorabbin Airport, with 28.1°C at 2:37pm. The old record was 27.4°C. South Australian May heat records broken Adelaide reached 29.4°C at 1:10pm (ACST) but several suburbs and localities in and around the city cracked the 30-degree mark, including Parafield with 30.9°C. While none of the Adelaide area readings were records, new day-time highs were set in at least five SA locations, while minimum temperature records were also broken. Mt Lofty, overlooking Adelaide, had its warmest May night on record with a mild low of 17.6°C. New South Wales May heat records broken May heat records in NSW were confined to the Lower Western and Riverina forecast districts in the southwest of the state. They included: Deniliquin reached 28.5°C (old record 28.0°C). Hay reached 29.2°C (old record 29.1°C). Ivanhoe hit 29.5°C (old record 29.1°C). What’s causing this record-breaking May heat?

Warm northwesterly winds ahead of an approaching cold front in the Great Australian Bight have pushed air all the way from Australia’s interior to the southeast corner of the continent. This is a pattern more typical of summer than late autumn. In set-ups like this, temperatures often tend to be just as warm on Victoria’s southern coastline (assuming no strong sea breeze) as in the state’s north. That’s why, at 2:10pm, the main Melbourne weather station at Olympic Park (26.2°C) was almost exactly the same temperature as Mildura (26.4°C) in northwest Vic. How long will this warmth last? It’s not done yet. Hobart, Adelaide and Melbourne (and plenty of places in between) can all expect another day with highs well into the 20s on Saturday. As the cold front approaches, cooler weather with showers will affect much of the southeast, and there’s the likelihood of a second, much more wintry outbreak just after midweek next week, with an early Thursday forecast high of just 14°C for Melbourne. *The temperatures mentioned in this story are not yet the official maximums for Friday at the time of publication.

Australia's 2025–26 tropical cyclone season featured seven severe tropical cyclones — well above the historical average of four to five — continuing a trend of increasing cyclone intensity in the Australian region. The 2025–26 Australian tropical cyclone season officially ran from 1 November 2025 to 30 April 2026. During this six-month period, Australia saw 11 tropical cyclones, with nine forming within the Australian region and two forming outside of Australia’s area of responsibility. Five of these systems made landfall, bringing severe weather to parts of the country. Image: Tropical cyclones that formed in, or moved into the Australian region during the 2025-26 season. Source: Weatherzone. While a season total of eleven cyclones is slightly above the long-term average of 9.5 systems, the season was notable for an unusually high proportion of severe cyclones forming in the region. Of the eleven cyclones, seven systems reached severe intensity (Category 3 or higher), compared to a historical average of approximately 4-5 severe cyclones per season. This is the third consecutive season with six or more severe tropical cyclones in the Australian region, following eight in 2024-25 and six in 2023-24. The seven severe systems of the 2025–26 season were: Narelle (Cat 5) Maila (Cat 5) Fina (Cat 4) Bakung (Cat 4) Hayley (Cat 4) Jenna (Cat 4) Mitchell (Cat 3) Of these seven severe tropical cyclones, four made landfall on the Australian mainland, with Narelle notably crossing the coast multiple times across three different states/territories. Cyclone activity during the season was not evenly distributed, with peak periods occurring during monsoon onsets and when tropical pulses, such as the Madden–Julian Oscillation (MJO), were active. The most active period occurred between February and March 2026, when the monsoon trough, MJO and warm ocean temperatures coincided. The 2025–26 season broadly followed the typical spatial pattern; however, the western region saw more cyclones than normal, with nine forming or moving into the area.

Climate drivers influencing tropical cyclones this season The active and intense 2025-26 tropical cyclone season occurred under the influence of above-average sea surface temperatures surrounding northern Australia, which were associated with La Niña, a negative Indian Ocean Dipole (IOD) and the background influence of climate change. This abnormally warm water was a dominant driver of tropical cyclone intensity, supporting: Rapid intensification events Higher peak cyclone intensity Longer-lived severe systems The northern Australian monsoon arrived earlier than usual on December 23, 2025, marking the first active phase of the wet season. This is typical of La Niña years, which often see an earlier monsoon onset. Once established, the monsoon became highly active and moisture-rich, contributing significantly to both rainfall and tropical cyclone development. Tropical cyclones and monsoonal lows also contributed significantly to seasonal rainfall totals, particularly inland, with above to very much above average rainfall observed across northern Australia. Cyclone trend in Australia: fewer cyclones but with greater intensity The number of tropical cyclones in the Australian region has decreased in recent decades, with an average reduction of around one system every 11 years since 1980, likely linked to broader climate change influences. This long-term decline also reflects strong El Niño-Southern Oscillation (ENSO) variability, with La Niña years typically producing more cyclones, while El Niño years are often associated with fewer systems.

While total cyclone numbers are decreasing, the proportion of severe tropical cyclones is increasing. Warmer ocean temperatures are a key driver of this trend, supporting more frequent rapid intensification and higher peak intensities. Tropical Cyclone Narelle- the most impactful system of the season Tropical Cyclone Narelle accounted for a disproportionate share of operational activity due to its duration and multi-region impact. It is highly unusual for a system to cross three Australian jurisdictions (Queensland, the Northern Territory, and Western Australia), making Narelle a rare “triple-impact” cyclone. This type of track is extremely uncommon in modern records. Narelle became the first tropical cyclone since 2005 to make landfall in three Australian states while maintaining tropical cyclone intensity, with the only other comparable cases since 1980 being Cyclone Ingrid (2005) and Cyclone Steve (2000).
