How often does it rain in Jacksonville?
Jacksonville records around 1288mm of rain a year, spread across about 148 days — roughly 41% of all days, or 12 days in an average month. In practice that makes rain a regular feature of running in Jacksonville rather than an exception — close to one day in two. A decent waterproof and a peaked cap earn their place in the kit bag year-round.
The wettest month is August, averaging 192mm across about 24 rainy days. The driest is November, with 61mm over roughly 8 days. Even in January, average lows stay around 8.9°C, so cold is rarely the limiting factor here. At the other end, July averages 31.8°C highs — hot enough that early morning and evening are the sensible windows, and hydration matters more than waterproofing.
Those are ten-year averages, not a forecast. What actually matters on the day is the next twelve hours — which is what the live verdict and hourly strip at the top of this page are for.
