monthly climate summary

The early taste of fall that delighted many Oklahomans at the end of August lingered through the first week of September before summer grabbed the remote control again. Gone were the autumn-like highs in the 60s and 70s, replaced by the more customary 80s and 90s. Despite that return to normalcy, Mother Nature couldn’t resist one more twist: for the first time since 2008, the Oklahoma Mesonet failed to record a single 100-degree temperature during September. The last triple-digit highs—likely the year’s final—came back on Aug. 28 at several sites in southwest Oklahoma.

August 2025 pulled a fast one on Oklahoma. Instead of the typical late-summer swelter, the month ended with a taste of fall as two powerful cold fronts shoved aside the heat. The final week brought gray skies, steady rain and highs stuck in the 60s and 70s — more like October than August. The chill was strong enough to break multiple records, including several record-low maximums and even a few outright record lows.

After months dominated by rain and severe weather, summer finally reclaimed the spotlight in Oklahoma during July. The state’s wet streak ended, replaced by rising heat and drying conditions. A lone tornado touchdown near Vance AFB extended the tornado streak to five consecutive months, bringing the 2025 total through July to 88. Sweltering July heat held off for much of the month but surged during the final two weeks—only to be abruptly cut short by an unusually strong cold front on July 31.

Oklahoma’s big weather stories this spring overwhelmingly involved tornadoes and heavy rains — and June was no exception. The month finished as the sixth-wettest June on record, at 7.22 inches, nearly 3 inches above normal. The preliminary tornado count swelled to 25, the second-highest for the month on record. But there was at least one silver lining to all that active weather: June saw drought completely eliminated from Oklahoma for the first time in nearly six years.

After April’s stormy chaos, the first half of May brought a rare lull in Oklahoma’s spring severe weather season. Aside from an active kickoff on May 1 — featuring large hail, damaging winds, tornadoes, and flash flooding — the state experienced a quiet 16-day stretch, interrupted only by a single report of half-dollar-size hail in far southeastern Oklahoma on May 16. But the break didn’t last: severe storms returned on May 17 and dominated the remainder of the month.

Just four months after Oklahoma shattered its all-time November rainfall record, the state did it again—this time in April. The statewide average rainfall totaled 8.74 inches, surpassing the previous April record of 8.32 inches set in 1942, with data dating back to 1895. Numerous locations posted similar records, including Oklahoma City, where 12.55 inches of rain fell, topping April 1947’s 11.91 inches and ranking as the city’s sixth-wettest calendar month since records began in November 1890.

Most months, nearly breaking an all-time tornado record would dominate Oklahoma’s weather headlines. However, March 2025 will be remembered for a different kind of disaster—one of the worst wildfire outbreaks in state history, overshadowing all else.

Like the villain in a ‘90s action movie, winter struck back with a vengeance in January following the unusual warmth that closed out 2024. Several strong cold fronts delivered blustery winds, snow, ice, and some of the coldest air the state had seen since the generational freeze of February 2021.

It seems every year is a momentous one for weather in Oklahoma, and 2024 was no exception, with two all-time records either tied or broken during the year. The National Weather Service (NWS) confirmed at least 152 tornadoes touched down in Oklahoma, surpassing the previous record of 149 set in 2019. This year’s total was bolstered by record-breaking monthly totals of 56 in April and 33 in November. Most of the tornadoes were of the weaker EF0 and EF1 variety, accounting for 34 and 71 events, respectively.

November 2024 will enter Oklahoma’s vast and storied weather lore as one of the most extreme months in state history, shattering records for both the highest statewide average rainfall and the most tornadoes ever recorded in November. This unprecedented combination of rain and storms has left an indelible mark on the state’s already dynamic weather narrative. The month also saw another extreme, drought—which had been rapidly intensifying since mid-summer—nearly eradicated by the historic rainfall.
