What started out as one of the coolest Septembers on record at Jacksonville International Airport (JAX), ended as one of the driest. Plus, 90-degree days continue climbing toward a record year.

Summer came to a crisp end

Remember when the beginning of September felt, dare I say, cool? The numbers speak for themselves as it was the 5th coolest start to the month of September, through Sept. 17, with an average temp of 76.8 degrees (-3.1°F below normal) in JAX (records for Jacksonville date back to 1871). The coolest low in September was 60 degrees on the 15th.

Fall started out hot!

The ninth month of 2025 helped inch JAX closer to the all-time annual record of 114 days at or above 90-degree highs. Currently, JAX is at 113 days, just shy of tying the record with only 92 days to go!
