🌡 The weather here, in general

Port St. Lucie is even-tempered by US standards. The warmest month (July, 89°F) and the coldest nights (January, 57°F) are only 32 degrees apart.

The thermometer rarely spikes — only about 37 days a year top 90°F — but it hardly needs to. Summer sits in the mid-eighties for months at a stretch, and with humidity on top of it the heat index runs well above what the air temperature suggests.

It is a wet place: about 56 inches of precipitation a year, peaking in September. Drainage and flash flooding deserve more attention here than in most of the country.
