JACKSONVILLE, Fla. – A thin veil of frost sparkles across lawns and car rooftops this morning, glinting under the first light before melting quickly in the sun. Much of northeast Florida woke up under a Frost Advisory, marking one of the region’s coldest starts so far this fall. Temperatures near 33°F have nipped tender plants and stunned gardeners from Saint Augustine to Duval and inland Flagler counties.
According to the National Weather Service in Jacksonville, readings dipped below freezing in low-lying inland areas before dawn. The advisory remains in effect until 8 a.m. as calm winds and clear skies allow frost to linger. Sensitive vegetation and outdoor pipes are most vulnerable; residents are urged to cover plants, bring in potted greenery, and protect pets from the morning chill.
By midday, sunshine will push temperatures into the upper 60s, beginning a steady rebound that lasts through the weekend. Thursday brings highs near 72°F with bright skies and light winds, while Friday will reach the mid-70s—perfect for outdoor events or early holiday decorating. The pattern remains dry and stable, with no rain expected through early next week.
The sudden chill follows a rare G4 solar storm that illuminated the Northern Lights as far south as Alabama Tuesday night. While the spectacle fades, minor radio or GPS disruptions could still occur today.
For now, Jacksonville shakes off its early winter tease with a stretch of classic Florida sunshine ahead—a reminder that even when frost finds its way south, warmth is never far behind.
