April 4 in Tulsa typically lands right in that pleasant spring window — a 67° high, 45° low, with only a 20% shot at rain. But the date has swung hard in both directions: 90° back in 1943 and a bitter 27° low in 1972 show just how wide open Oklahoma spring can be.
Tulsa's weather has real teeth on both ends — 113° in August 2011 and -13° just five years ago in February 2021, a 126-degree spread between its extremes. The wettest single day on record dumped 7.54 inches in July 1963, and a single February storm in 2011 buried the city under 13.2 inches of snow.
Summer runs hot and long in Tulsa, with highs averaging 93-94° from mid-July through August — plan accordingly if you're heat-sensitive.
