In Florida, our summers are marked by two weather related things: it is already at least 75 degF at sunrise, and we get a sea breeze driven rainstorm most afternoons between 3 and 8 pm.
The change to fall is marked by a shift in rain patterns. Instead of afternoon driven downpours, fall sees slower, constant rain that can last for days. This usually begins around mid September, and last until the end of November, although the rains usually are done by the end of October. I remember one year that it rained all of Thanksgiving week- that Monday all the way until Sunday.
Anyhow, we have our first fall rain storm today:
The best news is that our morning temperatures are dropping into the low 70s. Last week, the low at my house was 78 degF, and the high was 97. Today, the low was 72.
Fall is about two weeks early in Central Florida this year.
