Florida – Cool predawn air fades fast as sunshine spreads across northeast Florida. By midday, jackets feel out of place and car thermometers climb quickly under a bright February sun.

Jacksonville warms into the upper 70s today, flirting with early-season heat levels. Calm winds early turn light from the southwest, helping temperatures surge. Sidewalks heat up, palm fronds barely move, and the St. Johns River reflects a sky that looks more like April than midwinter.

According to the National Weather Service, above-average temperatures will dominate much of the eastern United States through midweek. Jacksonville sits squarely in that warm pocket, with highs well above normal and dry conditions holding through Thursday.

Wednesday stays mostly cloudy but warm, topping out near 75. A gentle breeze develops, adding a mild, humid feel by afternoon. Thursday brings more sun and another warm push, with highs nearing the upper 70s again. Evening temperatures remain mild, keeping patios busy after sunset.

By Friday, clouds increase but warmth lingers. Highs reach the mid-70s, still far from anything resembling winter. Drivers should note changing conditions late Saturday as moisture returns. Showers become possible by afternoon, with rain chances increasing Saturday night into Sunday. Roads could turn slick quickly after a dry, dusty stretch.

This warmth fits a larger pattern. NOAA’s 6–10 day outlook shows above-normal temperatures continuing into early next week across Florida. While rain chances rise, no sharp cool-down appears imminent. Signs of spring are clearly lining up, even as winter still clings to colder regions farther north.

For now, plan for sun, warmth, and hydration today. Keep umbrellas nearby for the weekend shift. Are you enjoying the February heat, or hoping for cooler air to return?
