Historical weather data, all-time temperature records, and monthly climate averages for Mexicali, Baja California, Mexico. Explore typical weather conditions by week for trip planning, and see how today compares to the historical record.
April 4th is a reliably warm, dry day in Mexicali, with an average high of 84° and just a 2% chance of any precipitation across 93 years of records. The date has seen wild swings, though — from a scorching 104° in 1961 down to a near-freezing 33° in 1945.
Mexicali plays in an extreme league: its all-time high of 122° on July 11, 1934 ranks among the most intense temperatures ever recorded in North America, and its all-time low of 16° in January 1937 proves even the desert can bite. The wettest single day on record barely cracked 2.56 inches, a reminder that this is one of the driest cities on the continent.
Mexicali runs hot from May through September, with average highs topping 100° for much of that stretch and peaking around 109° in mid-July — not a destination for the heat-averse. If you're looking for comfortable weather, January and December offer the mildest conditions with highs in the low 70s, and while winter brings the most precipitation, 'wet season' here still means barely a drizzle.
