Weather factors to check
- Timing lightning before beach or river outings
- Tracking hurricane and storm surge alerts
- Watching rip current and marine forecasts
- Planning around afternoon sea-breeze storms
Air Quality
Air quality is part of everyday weather planning, especially for workouts, commuting, wildfire smoke, heat, and sensitive groups. A local forecast should make that context easy to act on in Jacksonville.
Local Air Quality Answer
Air quality planning in Jacksonville works best when weather context is included, because heat, humidity, wind, smoke, dust, and stagnant air can change outdoor risk quickly.
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.
For Jacksonville, temperature, humidity, wind, and air quality together determine whether outdoor plans feel comfortable or risky.
WeatherAI helps connect air quality with forecast timing so you can adjust workouts, commutes, errands, and travel plans around Jacksonville.
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.
Local Planning Guide
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.
