Historical weather data, all-time temperature records, and monthly climate averages for La Verne, CA. Explore typical weather conditions by week for trip planning, and see how today compares to the historical record.
Today's date has a story worth knowing in La Verne — a foothill city where the San Gabriel Mountains shape everything from afternoon breezes to record-breaking heat events. Forty years of data show this spot can swing from 19° freezes to 109° scorchers depending on what the atmosphere decides to do.
La Verne's all-time high of 109° hit on July 22, 2006, a reminder of how brutal inland Southern California can get when offshore flow takes over. On the cold end, a stunning 19° reading on March 12, 1986 shows even this sun-drenched suburb isn't immune to a late-season Arctic plunge.
La Verne peaks in late July through early August, when average highs reach 89-90° — warm enough that the foothills can feel genuinely punishing. Winters are mild, with December and January averaging around 61-62°, making this one of the more comfortable places in the country to spend the cold months. Precipitation is concentrated in the winter months, so if you're chasing dry weather, summer delivers.
