Best time to visit Jacksonville

Jacksonville is a city of two halves. November scores 86 and July scores 38 — a 48-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. 7 of the twelve months sit within ten points of the best, so there is more than one right answer.

July is the warmest month at 32.9 °C and January the coolest at 17.7 °C — a 15.2 °C spread across the year. 132 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season. 11 nights a year dip below freezing.

There is a real wet season here. June to August carry the rain — up to 24 wet days in a month — while January, February, March, April, November and December drop as low as 7. That 17-day gap is the biggest single difference between a good month and a bad one in Jacksonville, and it moves further than the temperature does.

The sea is comfortable for swimming in April to December — 28.4 °C at its warmest against 19.5 °C at its coldest. The water peaks a month or two after the air does, so the best swimming falls later in the year than the best weather. Daylight runs from 10.2 hours in winter to 14.1 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are November, February, April. The one to think twice about is July. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
