Florida heat is building fast across Jacksonville, with patchy fog reducing visibility before 9 a.m. and temperatures climbing toward 90°F by mid-afternoon. Roads near NAS Jacksonville and along I-95 may start the day with reduced visibility, but bright sun quickly takes over, turning the afternoon hot and dry.
According to the National Weather Service in Jacksonville, fog clears early, giving way to sunshine with light winds shifting southeast by midday. Highs reach near 90°F today and push even higher Saturday, peaking around 91°F under mostly sunny skies. Calm morning air turns slightly breezy later in the day, but heat remains the main story.
Across Duval, St. Johns, and Clay counties, the weekend keeps that summer feel locked in. Saturday stays hot and bright, while Sunday dips slightly to 88°F with more clouds mixing in. Winds begin to pick up Sunday afternoon, especially near coastal roadways like A1A, signaling a shift.
By Sunday night, breezy conditions settle in with increasing cloud cover. That change brings a noticeable drop into Monday, where highs stall near 74°F despite sunshine. Expect gusty conditions that could impact high-profile vehicles on bridges and open roadways.
Plan outdoor activities early in the day to avoid peak heat. Stay hydrated and keep devices charged as winds increase late weekend. A warming trend returns later next week, with above-normal temperatures building again.
