Summer in Florida has yet to officially begin, but things are already heating up.

Ahead of Memorial Day, which most people in the U.S. consider the unofficial "start of the summer," Floridians will see temperatures hit potentially record-breaking highs next week . It's already warm and summery weather in Florida, but the heat wave will ramp things up and is likely a harbinger of a very hot summer ahead.

Here's when it usually starts getting hot in Florida, when the upcoming heat wave is expected to hit and a quick breakdown of the forecast for summer 2025 in Florida.

What month does it start getting hot in Florida?

Where you live in the state determines what month it will start feeling noticeably warmer for you. Florida is a peninsula, so the northern region of the state cools down faster and sees summer later in the year than the southern region of the state.

“Variation from the mean date of arrival and departure of the hot season increases from northern to southern Florida,” Florida State University’s Climate Center says . “The timing, frequency and strength of cold fronts from the interior of the nation vary greatly from year to year.”

For example, places in North Florida, like Tallahassee and Jacksonville, start seeing noticeably warm weather in May. But most places in South Florida, like Miami and West Palm Beach, started seeing summery weather in March, and can even see summer temps as early as February.

And this year, things are heating up quickly. A heat wave is on its way.

Florida weather this week: Is there a heat wave coming?

Yes. Record-setting high temperatures are expected across Florida, climbing up to the mid-90s in parts of the state, including Jacksonville, through the weekend and early next week.

The National Weather Service in Jacksonville is warning that, based on current forecasts, records could be set or tied not only for record highs – even the low temperatures could set a record for high minimums.

Temperatures above normal are expected from May 18 through May 22, especially for Florida, south Texas and stretching into southern Georgia, according to NOAA's Climate Prediction Center.

And although it will be hotter than is typical for this time of year, expected high temperatures in Florida don't compare to the triple digits forecast for parts of Texas , where some cities could see high temperatures of 113.

This orecast aligns with earlier predictions from the Old Farmer's Almanac, which predicted that summer 2025 was “ shaping up to be a doozy!" Its prediction said Florida is expected to be hot and dry this summer, although South Florida could see cooler, rainy conditions.

In much of the state, temperatures will reach the mid-90s this upcoming week, which is abnormally high for May in north Florida, specifically.

Is it going to be a hot summer in Florida in 2025?

Yes. This summer is predicted to be a hot one in Florida.

June through August could "feature sweltering heat, severe weather, intense wildfires and the start of a dynamic hurricane season," AccuWeather said in its summer forecast.

And NOAA's summer forecast predicted temperatures across the Sunshine State will likely be above-average for all of Florida.

What is the first day of summer in 2025?

It depends on what you consider the start of summer. To start, there’s a difference between the astronomical and meteorological first day of summer. And a lot of people in the U.S. see Memorial Day weekend as the unofficial “start of summer,” while those with kids in school might base the turn of the season on when school lets out for the summer season.

If you consider the start of summer to be the first sweltering temperatures of the year, the first heat wave is expected to hit on May 18 (see above).
