Alerts to prioritize
- Hurricane storm surge and St. Johns River flooding
- Near-daily sea-breeze lightning in summer
- Rip currents and nor'easter coastal flooding
- Occasional winter freezes in inland neighborhoods
Local Alerts
Useful alerts are specific, timely, and tuned to the places you care about. For Jacksonville, that means notifications should help you act before weather disrupts your day.
Local Alert Answer
Weather alerts around Jacksonville should be specific enough to separate routine forecast changes from conditions that need action. June through November is Jacksonville's key stretch, when daily sea-breeze thunderstorms overlap with hurricane season and peak rip current risk at the beaches.
The Atlantic sea breeze decides where storms fire on any given afternoon, so radar often shows heavy rain on one side of the St. Johns River while the other side stays dry.

Jacksonville has a humid subtropical climate with hot, wet summers and mild winters. At the Jacksonville station, the 1991-2020 reference averages range from a daily high of 66°F (19°C) in Jan to 92°F (33°C) in Jul. Monthly precipitation averages sum to 53.4 inches (1356 mm) per year.
The wet season runs May through October, when the Atlantic sea breeze fires near-daily afternoon thunderstorms. Hurricane season spans June through November, and storm surge can push far up the St. Johns River; Irma in 2017 drove record river flooding downtown. Fall and winter are mild and dry, though inland neighborhoods see occasional frosts. Spring is warm and pleasant but dry enough to raise wildfire concerns some years.
