The wet season in Central Florida lasts an average of five months. It generally begins in late May and runs through mid-October.
It’s exactly what its name indicates: Wet!
61% of our total annual rainfall is received during these five months.
There really isn’t a definitive start date or time, but there are a few signals that alert us to the fact that the rainy season may be beginning:
1. Cold fronts stop moving through Central Florida
2. Frequent (almost daily) showers and/or thunderstorms form, mainly along sea breeze collisions
3. The low temperature and dew point temperature is consistently 67-70°
Forecasters at the National Weather Service office in Melbourne, Florida make the official “call” of when the wet season has begun for Central Florida. They usually wait a few days, or sometimes weeks, after we “think” the season has started before determining the official start date for that year.
On average, the rainy season begins in Orlando on May 27 and in Daytona Beach on May 29. However, it has started as early as May 5 in Orlando, and as late as early July in Daytona Beach.
