April 4th in McComb lands right in the sweet spot of spring, with an average high of 75° and low of 51° across 77 years of records. There's a 36% chance of rain today — not a lock, but worth keeping an umbrella handy. The date has seen wilder swings, though: a toasty 89° back in 1967 and a hard freeze down to 28° in 1987.
McComb plays in the extremes — this is a place that has baked at 106° in the August heat of 2000 and plunged to a brutal 2° in January 1985. A single day in October 1964 dumped nearly 11 inches of rain, and even a rare 4.7-inch snowstorm showed up in February 1968. The range from 2° to 106° tells you everything about the climate here: it goes hard in both directions.
McComb summers are serious business, with average highs in the low 90s from June through August and a peak around 92° in early August. If you're looking for relief, January is the coolest month at 60° — which, frankly, still isn't bad. Late August into early September is the wettest stretch of the year, so plan outdoor events accordingly.
