JACKSONVILLE, FLA – Jacksonville is about to feel the sizzle of an early-season heat wave, as inland temperatures surge into the lower 90s—arriving nearly a month ahead of schedule. This unseasonable warmth will begin on Wednesday and intensify through the weekend before relief comes in the form of a cold front on Monday.

With this week’s heat wave, those numbers are about to be rewritten.

Wednesday marks the beginning of the temperature spike, with highs climbing well above seasonal norms. As inland areas bake, the warmth will gradually extend toward the coast, peaking on Sunday when Jacksonville could flirt with the 90-degree mark. Several daily records are at risk of falling, with previous highs in the upper 80s to lower 90s set to be challenged.

While summer-like heat will dominate the rest of the week, a cold front arriving Monday will bring a welcome cooldown. The pattern shift should bring a return to more typical spring temperatures, offering a brief reprieve before the inevitable summer swelter returns.

Last year, Jacksonville had 102 days at 90°F or warmer—twice as many as a typical year over a 30-year average. But this early heat wave doesn’t necessarily mean we’re in for another record-breaking summer scorcher. With any luck, Mother Nature will show a little mercy this time around.
