April 5th in Jacksonville has historically been a transitional day — expect something in between, with an average high of 68° and low of 46° based on 68 years of records. The date has seen everything from a balmy 87° (1967) to a frost-flirting 31° (1987), so the range is real. There's a 35% chance of rain, though snow is essentially off the table.
Jacksonville plays it extreme when it wants to — the mercury has hit 113° in July 1986 and crashed to -6° during the brutal February 2021 freeze. On the wet side, a single day in September 2008 dropped nearly 8 inches of rain, and a January 1988 snowstorm buried the area under nearly a foot of snow.
Summer is the dominant season here, with highs pushing into the low 90s from mid-July through August and a slow fade into fall. Winters are mild but not toothless — January highs only average 49°, and cold snaps can be sharp. If you're watching for rain, late April is the wettest stretch of the year.
