Traveller notes on Jacksonville in May

Other months in Jacksonville

Regulars are consistent this is cold-by-Florida-standards weather, good for strolling the beach rather than sitting on it, with surfers and walkers out but few sunbathers even on a nice day. Our row backs that cool read, 20.8C over 10.7C nights feeling 9C, with 95.2mm of rain across 6.2 days. Regulars are specific this runs noticeably cooler than the Gulf Coast or Miami, a real 10-15 degree Fahrenheit gap from Orlando alone, so anyone chasing genuine beach weather in December is pointed further south instead. Visitors coming from colder Northern climates are just as consistent that they find this same weather wonderful rather than cold, a real perspective gap regulars call out directly. The record: humidity 79 percent, 7.2 hours of sun, a 14.9 kph wind and AQI 37.

Regulars are candid that this Florida month can genuinely deliver hot, cold, sunny and rainy conditions within a single day, and the practical advice is to come prepared for all of it and stay willing to change plans on short notice - early April is called more of a mixed bag than the more reliably good beach days of late April. Our row backs the warm-but-changeable read, 27.9C reading as 29C over 16.7C nights, with 93.6mm of rain across 8 days. Regulars are more confident recommending late-month dates specifically for beach plans, while early-month visitors are steered toward flexible, weather-independent activities like the Riverside Arts Market as a backup. The record: humidity 69 percent, 10.6 hours of sun, a 16.8 kph wind and AQI 48.

Regulars refuse to predict this month and say so: February here can run anywhere from 80F down to 30F, usually mid-forties to mid-sixties, and the only sensible advice is to pack for both. Our row's 23.6C over 12C is the middle of that spread. The beach follows the same rule - too windy and cold one day, beautiful the next - and the water is at its coldest of the year, about 56F, so this is a walking, dog-and-kite month rather than a swimming one. Late February brings the compensation: the sand is clean and close to empty. Our 87.3mm falls across 8.4 days. The record: humidity 77 percent, 8.3 hours of sun and AQI 46.

November in Jacksonville is mild and mostly pleasant - regulars give the 65 to 75F range for early November, with cool fronts pulling nights into the 50s later in the month, which our row renders as 23.7C days over 14C nights. The question they get asked is about water, and the answer is a qualified no: the ocean off Jacksonville Beach sits in the high 60s Fahrenheit falling into the low 60s, chilly for most people, and an unheated hotel pool will be the same. Nearby Ponte Vedra reports a 72F high and 57F low as the November average. So: layers, a light jacket for the evening, and treat the beach as somewhere to walk. The record: 5.8 precipitation days carrying 66.1mm, humidity 77 percent and 8 hours of sun.
