April 4 in Tijuana is a reliably mild late-winter day, with an average high of 69° and very little drama — just a 14% chance of rain and zero chance of snow. That said, the date has seen its share of swings: a balmy 82° in 2021 and a chilly 40° low back in 1999.
Tijuana's weather is mostly tame by global standards, but the extremes tell a spicier story. The city has touched 110° (July 2006) and dipped to a surprising 27° (January 2007), and a single February day in 2004 dropped 2.36 inches of rain — a month's worth of drama in 24 hours.
Tijuana runs warm and dry nearly year-round, with highs ranging from a mild 67° in winter to a peak of 83° in late August and early September. If you're chasing the best beach weather, aim for July through September; if you want to avoid rain, skip February, which is both the coolest and wettest stretch of the year.
