Winter's Warmest Night Shatters Melbourne Records

Melbourne experienced an unseasonably warm start to winter, with record-breaking temperatures recorded across the metropolitan area. Early on Thursday, June 19, 2026, temperatures remained just below 20 degrees Celsius well after midnight. A specific overnight low of 16.4 degrees Celsius was noted at the Olympic Park weather station just before 10 pm on Wednesday, June 18, 2026.

This extended period of warmth made the preceding 24-hour block the warmest June night on record, according to the Bureau of Meteorology. Senior Meteorologist David Crock noted that these overnight temperatures were comparable to a regular summer night in Melbourne. He added that while the recent stretch was warm, more typical June conditions are expected imminently.

Looking ahead, cooler air is anticipated, with forecast high temperatures around 14 degrees Celsius and significantly cooler nights. This shift will likely make the weather feel quite cold after the recent unusual warmth. The weekend, including Saturday, June 21, Sunday, June 22, and Monday, June 23, 2026, is forecast to have maximums of around 14 degrees Celsius.

In addition to the temperature changes, a warning for strong winds is currently in effect for several coastal areas. Heavy rainfall experienced in other states is also beginning to impact western Victoria, with more showers and potential thunderstorms forecast for Thursday afternoon and continuing over the next few days.
