End of rainy season right around the corner

We are winding down the rainy summer season here in south Florida, and getting ready to start the dry/cool season.

This year's rainy season began back on May 29. On average the rainy season lasts from May 21 through October 17. The latest end to the wet season was Nov. 5 in 1995. The earliest end was Sept. 24 in 1983.

The past 5 years have ended around the median date: 2016 - Oct.16, 2015 - Oct. 17, 2014 - Oct. 15, 2013 - Oct. 10, 2012 - Oct 26.

The wet season is when South Florida receives the majority (~70%) of our rainfall. This year we are running a little wetter than normal, but since the dry season was much drier than normal, we are still down about 6 inches for the year.

There is a cold front on the horizon, about a week away (Oct. 25) that if it holds as forecast, would put an abrupt end to the rainy season.

This year's long range forecast for the winter generally looks warmer and drier for South Florida.  That coincides with the prediction of a La Nina forming in the Pacific.
