Melbourne is in full summer mode right now, with sunny conditions and highs reaching 40°C paired with northwesterly winds ranging from 15 to 30 km/h. If you're planning outdoor activities, bring plenty of water and sunscreen, because these temperatures demand some serious heat management.
January 2026 has tracked nearly identical to historical averages at 27.7°C, though upcoming days are forecast to hit 29.6°C, slightly above the long-term average. Daytime temperatures typically reach 26°C in Melbourne during January, falling to 14°C at night, so those 40°C days are pushing beyond the usual summer range.
Melbourne sees roughly 9 hours of bright sunshine each day in January, making up about 60% of daylight hours. You can expect around 10 days with some rain during the month, with average rainfall hitting 51mm. The good news: the current sunny stretch looks solid for the next few days, so get outside while conditions are clear. Just remember to stay hydrated in this heat, especially if you're planning anything strenuous.
