Southeast Florida –Weather (statistics are for West Palm Beach)

Seasons – there are principally two: the wet season (summer) and the dry season (winter).  The wet season roughly corresponds with Hurricane Season, which is officially designated as June 1 through November 30. The wettest months are June, August and September, with average rainfall totals 7.6, 6.7 and 8.1 inches, respectively.  You should know that during the rainy season we get rain virtually every day – Count on it.  The good news, though, is that we get sun virtually every day as well.  The rain typically rolls in in the late afternoon, say 3:00 – 4:00 p.m., and is over by, say 7:00 p.m.  (Unless there’s some sort of tropical system involved, when we can get unrelenting rain for a week.)  By rain, during the rainy season, we’re talking about sheets and/or buckets or rain – the kind that reduces visibility to just about zero.  It’s a cacophony of bajillions of huge, driven splats, accompanied by an amazing amount of lightning – Florida is the lightning capital of the U.S.  And the sheets can come on in an instant – it can be completely dry in one spot, while a spot 50 feet away is experiencing a deluge.

Get ready to sweat!  Most first timers start sweating the moment they step out of the airport.  The relative humidity level is HIGH.  Monthly morning average relative humidity is 85% for June through November, but daily humidity levels frequently top 95%. 

It is highly unlikely that you will ever need a jacket if you visit in June through September.  The only exception would be for your flight or the over-air-conditioned buildings.  The average low temperature for those months is 75 degrees F.  The coldest it has ever been during those months is 60 degrees F.  DO bring shorts.  The average high temps are in the 90s and the humidity makes it feel a lot hotter. 

Winter is probably the main reason people come to Florida.  High temperatures average 76 degrees F in December - February.  Average low temperatures vary from 57 – 60 degrees F for those months.  The record lows are 24 degrees F in December, 26 in January and 27 in February.  But usually the lows occur only in the wee hours of the morning and by mid morning it has warmed up considerably.  A light jacket or sweatshirt is probably enough to get you through. To Floridians, winter brings low humidity.  It’s still enough to make an Arizonan wilt, but for us it’s dry – morning average relative humidity of about 58% in December - May.
