With just over five weeks of summer remaining, many in Oklahoma are already counting down the days until the September breeze brings some relief from the persistent heat. But don’t put away your fans just yet—this fall could feel more like a summer encore.
According to the latest long-range outlook from the Old Farmer’s Almanac, fall 2025 in Oklahoma is shaping up to be warmer than usual. In particular, September is projected to kick off with above-average warmth, pushing temperatures to around 69°F (20.5°C), just a notch higher than the historical norm—but enough to extend that summer feeling.
After a season marked by severe storms, heavy rains, and even localized flooding, the fall months are expected to bring a notable shift. Rainfall is forecast to be below normal, meaning drier conditions for much of the state. Despite that, sunny skies will dominate, interrupted occasionally by brief cooldowns or light storms that won’t linger.
Come October, temperatures should balance out, returning to seasonal averages. However, forecasters warn of an unusual setup: a warm start and finish, with a brief but sharp cold snap likely to hit mid-month. That variability could keep residents across Oklahoma on their toes.
Expect average rainfall in October, though conditions may vary between the northern plains and the southern counties, as cooler air begins to settle across the central United States.
