When will Florida see cooler temperatures? Here's what you can expect for winter 2024-2025

It's July. It's Florida, and that means it's hot.

As the National Weather Service issues regular heat advisories, warning residents and visitors alike of heat index numbers climbing as high as 112, we can't help but wonder when winter and cooler temperatures will arrive.

OK, to repeat, it's Florida. It's July, so yes, there are several more months of hot temperatures ahead. And we haven't forgotten that in Florida, "winter" is more of a term applied to when we may be able to turn off the air conditioner and open the windows ... for maybe a day or two.

So when will "cooler" temperatures arrive in Florida and what can we expect for the 2024-2025 season? Remember La Niña? That weather system is not only increasing the chances for more tropical cyclones in the Atlantic basin this year, but also affects what we can expect this winter.

When does winter start?

The answer to the question "when does winter start" depends on which winter you're referring to: meteorological or astronomical.

Astronomical seasons are based on the position of Earth in relation to the sun, whereas the meteorological seasons are based on the annual temperature cycle, according to the National Centers for Environmental Information.

Meteorological seasons are the three-month periods we commonly refer to when talking about spring, summer, fall and winter. Winter months are: December, January, February.

Astronomical seasons are based on the position of the earth as it makes its annual trip around the sun, according to NOAA. Seasons are defined by the two solstices and two equinoxes. Astronomical winter months will run from the December solstice on Dec. 21, 2024, until the spring equinox on March 20, 2025.

How does La Niña affect Florida temperatures?

A lot has been said about how La Niña conditions this year are affecting the forecasts for a very busy hurricane season.

But La Niña has a wider impact than providing conditions perfect for developing tropical cyclones. It also impacts weather across the U.S.

For Florida, La Niña usually brings dry and warm winters, according to the National Weather Service and NOAA.

Here are the early predictions for what the winter months may bring.
