September is the month where we have the most passionate hatred for the summer heat. It's also the month we keep a weary eye on the Gulf of Mexico and the Atlantic Ocean. Football season is kicking, and we're anticipating that first cold front.
The beginning of September is just like August. Normal high temperatures are around 92 degrees. But by the end of the month that average drops to 85! Even better, the night time low on average drops from the low 70s early in the month to 65 by September 30th. Officially fall doesn't begin until 3:44pm on September 22. You've probably already noticed the morning light starting later, and the evening sunshine leaves a little earlier. Your eyes aren't tricking you. We will lose 15 minutes of daylight in the morning and 35 minutes in the evening over the course of the month.
Hurricane season peaks during September, but this year has been pretty mundane so far. Six named storms, but no hurricanes. No hurricanes through August has only happened a handful of times over the past 50 years. Most of those years still ended up with an average count, but 2001 brought 9 hurricanes by season's end. September normally brings about 3-4 named storms with two becoming hurricanes. It's also the most likely month for "Major Hurricanes" meaning Category 3 or higher.
Looking for that first cold front with temperatures in the 50s? The average date the first 59 degree temperature in fall occurred over the past 10 years is September 29th. The earliest was September 6, 2011 and the latest was October 13, 2004. (There was a rare cold front that dropped the temp to 59 degrees on August 15, 2004. But this wasn't included in the calculation)
