This summer has a 50% chance of being hotter than average in most of Florida, according to the National Weather Service Climate Prediction Center.
Zoom in: Historically, a normal summer day in Miami has a high of about 89° and a low of 76°, per NWS.
The intrigue: While summer technically begins June 20 in the northern hemisphere, in South Florida, forecasters have had a hard time pinpointing when the sweaty season begins.
A government study of climatological records between 1956 and 1997 found that the median date for the start of summer in South Florida— based on factors like daily minimum temperatures and precipitation amounts — was May 21 and the median end date was Oct. 17.
What to expect: "The hottest period is typically in July and August when the maximum daily heat index can frequently reach or exceed 100F," the NWS says.
The NWS is also predicting above-normal rainfall for South Florida this summer.
The wet season, which began May 15 and ends Oct. 15, is typically when South Florida sees about 60-70% of its average yearly rainfall.
