Weather in Jacksonville, Florida

Six Jacksonville weather guides sit under this hub: two on how the climate behaves through the year and four on the storms and cold snaps residents still talk about.

The seasonal weather patterns guide explains the humid subtropical climate and the split between a wet summer and a dry, cooler winter. The hurricane season guide covers storm surge, river flooding and how emergency management works in Duval County. The snow and freezes guide covers the city's rare snow and its hardest freezes. The historical storm impacts guide follows hurricane flooding along the St. Johns River, the Hurricane Dora (1964) guide covers that storm's local impact, and the Tropical Storm Fay (2008) guide covers that storm's warnings and river flooding.

This page gives the numbers those guides build on: the official normals at Jacksonville International Airport, the last five years of heat, cold and rain, and the drought the water management district reported in September 2026. Last verified: October 18, 2026, by pulling the 1991 to 2020 normals and the 2021 to 2025 yearly counts for Jacksonville International Airport from the ACIS climate database, and by re-reading the NWS Jacksonville office page, the National Hurricane Center climatology, JaxReady's zone page and the St. Johns River Water Management District's September 2026 drought update.

Jacksonville averages 69.3 degrees Fahrenheit and 53.40 inches of rain a year at Jacksonville International Airport under the 1991 to 2020 normals, with a normal annual snowfall of 0.0 inches (NOAA ACIS normals).

The monthly normals split the Jacksonville year into a wet summer and a drier rest of the year (NOAA ACIS monthly normals). From June through September each month normally brings between 6.77 and 7.60 inches of rain, with June the wettest at 7.60 inches and September close behind at 7.56. November is the driest month at 2.00 inches. July is the hottest month with an average high of 91.9 degrees, and January is the coolest with an average low of 42.9 degrees. All figures are for the single Jacksonville International Airport station, USW00013889.

Recent years at Jacksonville International Airport have brought more 90 degree days each year, from 65 in 2021 to 113 in 2025, while 2025 was also the driest of the five years with 42.34 inches of rain (NOAA ACIS yearly data).

The yearly counts come straight from the airport station record (NOAA ACIS). 2024 was the wettest of the five years at 62.81 inches, above the 53.40 inch normal, and 2025 the driest at 42.34 inches. Freezing nights ranged from 5 in 2021 to 17 in 2025, and the coldest reading of the period was 20 degrees in 2022. Five years is a short window, so the table shows how much single years swing around the normals rather than a long term trend.

Jacksonville is exposed during the Atlantic hurricane season, which runs from June 1 to November 30 and peaks on September 10, with most activity between mid-August and mid-October, according to the National Hurricane Center (National Hurricane Center).

For Jacksonville planning, the hurricane center says that under the 1991 to 2020 climate period an average Atlantic season has 14 named storms, 7 hurricanes and 3 major hurricanes (NHC). In the airport normals, August and September bring 6.88 and 7.56 inches of rain (NOAA ACIS).

Evacuation planning belongs to the consolidated City of Jacksonville and Duval County Emergency Management, which publishes zones lettered A through F on JaxReady (JaxReady). Zone A is the most vulnerable and is evacuated first, including manufactured and mobile homes; evacuation then widens from B to E as storm effects grow. Zone F is different, covering areas likely to flood from rainfall or other hazards. JaxReady notes that most of Duval County's low lying areas are along the coast and rivers, and that the interaction of the river systems with the Atlantic makes the county's zones more complex than most. Zones can be looked up by address on the JaxReady map or app.

Snow is rare enough in Jacksonville that the 1991 to 2020 normal annual snowfall at the airport is 0.0 inches, but the airport recorded freezing nights in every year from 2021 to 2025 (NOAA ACIS normals).

Between 2021 and 2025 Jacksonville International Airport logged at least 5 nights at or below 32 degrees every year, and 15 in 2022 and 17 in 2025 (NOAA ACIS). The lowest reading each year ranged from 20 to 29 degrees. January is the coldest month in the normals, with an average low of 42.9 degrees (NOAA ACIS monthly normals). The snow and freezes guide covers past snow and hard freezes in detail.

Not as of the district's September 3, 2026 update: Duval County still had a 15.45 inch 12-month rainfall deficit on August 31, 2026 (St. Johns River Water Management District).

The St. Johns River Water Management District said its Phase III Extreme Water Shortage declaration remained in effect within affected areas, while noting that recent rainfall had improved conditions. The airport station had already recorded only 42.34 inches of rain in 2025, against an annual normal of 53.40 inches (NOAA ACIS). The district's September 3, 2026 update said much of its territory had seen roughly a year of below-average rainfall, and that deficits in the Lower St. Johns River Basin were among the largest in the district, with Clay County at 15.46 inches, Bradford County at 17.34 inches and Baker County at 19.65 inches (SJRWMD). The district asks residents to irrigate only on their designated watering day and during allowable hours, and the water service guide lists the JEA watering days.

Official Jacksonville forecasts and warnings come from the National Weather Service forecast office in Jacksonville, while City of Jacksonville and Duval County Emergency Management publishes the evacuation zones on JaxReady.

The NWS Jacksonville office page carries the local forecast, current hazards, a daily briefing, storm report submission, marine and river observations and outlooks (NWS Jacksonville). Its October 2026 headlines included an El Nino Advisory, the NOAA winter 2026 to 2027 outlook released October 15, and Skywarn storm spotter class schedules for 2026 to 2027.

On October 18, 2026, the JaxReady zone page showed the Jacksonville Emergency Operations Center status as not activated (JaxReady). JaxReady says the city and Duval County Emergency Management work with NOAA, the National Weather Service, the North East Florida Regional Planning Council and public safety experts on the zone maps, and that when a storm approaches, local government will work with the National Weather Service and other partners to say which zones need to evacuate. The JaxReady app is offered for iPhone and Android. The hurricane season guide covers surge and river flooding in more depth.
