Weather in September

September in Oklahoma heralds the onset of fall, bringing with it a refreshing respite from the summer's intense heat. Temperatures during this month transition, ranging from a comfortable 60°F (15.6°C) to a more temperate 88°F (31.1°C). By the latter half of the month, the decline in mercury becomes more pronounced, ushering in the much-anticipated fall season.

The west, including the panhandle, begins to see a more marked decrease in temperatures compared to the humid southeastern regions. However, even in the southeast, the humidity starts to recede, making the warmth of the day more bearable and nights pleasantly cooler.

September's rainfall is moderate, particularly in the eastern portion of the state, which often sees the second-highest precipitation of the year after May. These rains, typically in the form of mild showers, provide a fresh outlook, revitalizing the landscapes and preparing them for the seasonal shift.

The threat of tornadoes continues its downward trend in September. While it's always wise to remain vigilant due to Oklahoma's positioning in "Tornado Alley", the frequency of these twisters is much diminished during this month.

The state begins to don a tapestry of colors, with shades of gold, orange, and red painting the landscapes.
