Average temperatures in Melbourne typically range from 54°F to 89°F over the course of the year, with winter averages in the mid-60s°F and summer averages in the upper 80s°F. Winters are mild by most U.S. standards, with freezing temperatures rare -- part of the draw for anyone relocating from a colder climate.
Rainfall
Melbourne receives about 54 inches of rain per year on average, with most precipitation falling during the summer months of June through September; August and September historically tie as the rainiest months in the area, per National Weather Service Melbourne data. Afternoon thunderstorms are a routine part of the summer pattern.
Hurricane Season
Hurricane season runs June 1 through November 30. High pressure often keeps direct hurricane landfalls from occurring in this specific area, but the region regularly experiences high winds and heavy rain from passing tropical systems even without a direct hit. Storm-surge and coastal-flooding exposure is a real risk category tied to the Indian River Lagoon and Atlantic coastline both -- see the insurance-hazard-costs topic page for how that breaks down between mainland Melbourne and the barrier-island beach towns.
Humidity and Daily Comfort
As a humid subtropical climate, Melbourne's summer months combine high heat with high humidity, which affects daily comfort more than raw temperature numbers alone suggest. Air conditioning is a year-round utility expense rather than a purely seasonal one for most of the year -- see the cost-of-living topic page for the broader utilities picture.
Key takeaways
- Average temperatures range from 54°F to 89°F over the year; winter averages in the mid-60s°F, summer averages in the upper 80s°F; winters are mild with rare freezing temperatures.
- About 54 inches of rain per year on average; August and September are historically the wettest months.
- Hurricane season runs June 1-November 30; direct landfalls in this specific area are relatively infrequent, but storm-surge and heavy-rain exposure via both the Atlantic and the Indian River Lagoon are real risks even without one.
- Humid subtropical summers mean high heat-index days and near-year-round air-conditioning use, a real factor in utility costs.
