Warrnambool has recorded one of its wettest and warmest Junes on record, with the city's latest weather statistics highlighting an unusually mild start to winter across south-west Victoria. According to the Bureau of Meteorology (Bo M), June 2026 delivered significantly above-average rainfall while average temperatures ranked as the third highest recorded for the month since local records began.
The exceptionally wet month brought repeated rain events throughout June, leaving paddocks saturated, waterways flowing strongly and soil moisture levels well above normal across the region. Farmers welcomed the abundant rainfall after several drier seasons, although some reported delays to winter cropping and livestock management because paddocks became difficult to access. The rainfall also replenished dams and improved water security heading further into winter.
Despite the frequent rain, temperatures remained noticeably warmer than expected for early winter. Average minimum and maximum temperatures both finished well above the long-term June average, making the month the third warmest June recorded in Warrnambool. Overnight temperatures rarely fell to the frosty levels typically experienced during winter, while daytime temperatures remained relatively mild despite persistent cloud cover.
The Bureau of Meteorology's daily observations show several significant rainfall events during the opening week of June, including more than 20 millimetres falling on 2 June alone. Monthly observations also indicate that rainfall was spread across numerous days rather than arriving in a single major weather event, helping maintain consistently wet conditions throughout the month. Average temperatures reached approximately 14.9°C for daytime maximums and 7.4°C for overnight minimums, both above historical norms.
Local meteorologists said the combination of frequent low-pressure systems crossing southern Australia and moisture-rich northwesterly airflow contributed to the unusual weather pattern. Instead of the colder, drier conditions often associated with early winter in south-west Victoria, Warrnambool experienced repeated fronts that delivered widespread rainfall while preventing temperatures from dropping significantly.
The warm and wet conditions were reflected across much of western Victoria, where several towns also recorded above-average rainfall during June. While the abundant rain has benefited agriculture and regional water supplies, prolonged wet conditions have also created challenges for road maintenance, construction projects and sporting events, with some local competitions forced to postpone matches because grounds became waterlogged.
Climate specialists note that individual months cannot be viewed in isolation, but the latest figures continue a broader pattern of increasingly warm winters being observed across many parts of Australia. While rainfall varies considerably from year to year, average temperatures have shown a long-term upward trend, contributing to more mild winter conditions even during wetter periods.
With July now underway, forecasters expect south-west Victoria to remain unsettled, with further cold fronts likely to bring additional rainfall. Residents are being advised to prepare for continuing wet conditions while taking advantage of improved water storage levels following one of Warrnambool's most remarkable June weather records in recent history.
