JACKSONVILLE, Fla. – It seems like it rained every day this summer and it almost has. Since the start of June through Sunday, there have only been 37 days without rain at Jacksonville International Airport.
But fall begins on Wednesday and the Autumn Equinox is a turning point to drier air. A cold front due to pass through Jacksonville on Thursday pushes out the moisture right on schedule.

September is typically the wettest month in Jacksonville due to an increase in passing tropical systems; however, the month has resulted in 4.73″ inches of rain just below a breakeven average.
The end of September marks the end of the rainy season which began in June. For the last four months rainfall has been above average.
About 20% of Florida is covered by sea breeze showers between 1 and 4 p.m. from July through August. Jacksonville fits into that description as every month from June through August had a surplus. So far through mid-September, the surplus of rain is just below 3.75 inches.
Fall brings less rain and the transition can be rapid -- from the wettest in September to the driest in November.
