April 4th in Selma typically lands squarely in spring sweet-spot territory — 78 years of data puts the average high at 73° with a low around 47°. It's rarely dramatic: there's only a 15% chance of rain and essentially no shot at snow, though temperatures have swung from a chilly 33° (1999) to a warm 88° (1952) on this date.
Selma earns its place in California's Central Valley reputation — the all-time high of 114° on July 11, 2021 is no joke, and even the coldest recorded day hit just 18° back in January 1949. Rainfall is rare enough that a single day in March 1995 that dropped 2.38 inches still holds the all-time record.
Summer in Selma is relentlessly hot, with late July averaging a high of 100° and the mercury routinely touching 99° throughout the month. If you're heat-averse, aim for January through March, when highs stay in the 50s and 60s — though that's also when the bulk of the rain falls, peaking around early February at about a half-inch per week. Spring and fall offer the most comfortable windows, with April and October both averaging highs in the mid-to-upper 70s.
