How hot will August be for Alabama? Here’s what one weather forecast predicts
August is typically one of the hottest months of the year in Alabama. But will August 2025 be hotter than average?
Forecasters are leaning that way.
A temperature outlook for the month of August from NOAA’s Climate Prediction Center suggests most of Alabama will have a 33-40 percent probability of above-average temperatures over the course of this month.
Parts of north and west Alabama are the exception. According to the CPC those areas will have equal chances of above-average or below-average temperatures this month. (See the full U.S. forecast at the top of this post.)
But there could be increased chances for rain to help mitigate that.
The precipitation outlook for August, also by the CPC, shows increased probabilities for above-average rainfall for the entire state over the next month:
Northwest Alabama is forecast to have a 33-40 percent probability of above-average rainfall. Parts of north, central and west Alabama will have a 40-50 percent chance.
The highest odds for rain will be for parts of south and east Alabama. Those sports will have a 50-60 percent probability for above-average rainfall.
What is average, though?
Here is a look at average August high and low temperatures and rainfall for a few Alabama cities:
- Birmingham: Average high 90.6 degrees; average low 71.3 degrees; average rainfall 4.35 inches
- Cullman: Average high 87.4 degrees; average low 65.8 degrees; average rain 4.13 inches

The first weekend of August will bring some cooler temperatures to much of the state, and highs on Sunday have the potential to stay in the 70s for parts of eastern Alabama.
Here’s the forecast for Sunday:

However, those cooler temperatures won’t last long.
The Climate Prediction Center’s six- to 10-day temperature outlook is forecasting a decent probability of above-average temperatures for Alabama from Aug. 6-10:

The exception is parts of north and east Alabama, which could have near-average temperatures.
The precipitation outlook for the same time period includes 33-40 percent chances for above-average rainfall for the entire state:

One other thing to keep in mind is that the Atlantic hurricane season typically becomes more active in August, which could bring more rain to Alabama.
There’s nothing brewing in the Atlantic, Gulf or Caribbean as of Friday, but look for activity to increase through the end of the month.
The CPC’s tropical outlook shows increased odds of activity near the U.S. from Aug. 6-12 but no activity from Aug. 13-19:
