How extreme does Jacksonville Beach's weather get?

The hottest, coldest, wettest and snowiest days Jacksonville Beach has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 50+ years of daily weather observations (1971–present), from the Jacksonville Beach station. Updated through June 2026 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Jacksonville Beach's record heat sits well above even a hot day for the season — February's 115°F is about 47°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Jacksonville Beach's warmest days reach the high 80s°F and its coldest nights drop to the high 40s°F. But across the record it has gone as high as 115°F and as low as 0°F. A single day has delivered over 13 inches of rain or close to 3 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
