April 4th in Los Banos lands right in that sweet spot of spring, with a typical high of 73° and low of 45°. The date has seen its wild swings over 107 years of records — from a scorching 91° in 2000 to a freezing 32° back in 1945. There's a modest 17% chance of rain today, but snow is off the table entirely.
Los Banos doesn't mess around when it comes to heat — the all-time record of 116° set on July 25, 1931 puts it firmly in Central Valley extreme territory. On the other end, a brutal 14° in January 1949 proves winter can bite. Rainfall is rare enough that a single day in 1914 dropping 2.4 inches still holds the all-time record over a century later.
Los Banos runs hot and dry for most of the year, peaking in mid-July with average highs of 97° and barely cooling until October drops things back to 80°. If you're looking for the most comfortable stretch, spring (March–April, 68°–75°) and fall offer relief on either side of the brutal summer. Rain is almost exclusively a winter affair, with late December the wettest week of the year at just under half an inch.
