Historical weather data, all-time temperature records, and monthly climate averages for Lake Elsinore, CA. Explore typical weather conditions by week for trip planning, and see how today compares to the historical record.
April 5th in Lake Elsinore is a genuinely pleasant day on average — expect a high near 75° and a low of 44°, with only an 11% chance of rain. But the date has range: it hit 103° back in 1989 and once dropped to a freezing 24° in 1955, so 125 years of history shows this spring date can surprise.
Lake Elsinore plays for keeps on the extremes — the all-time high of 118° in August 1933 puts it firmly in serious Inland Southern California heat territory, while a bone-chilling 15° in January 1963 proves winter isn't always mild. The wettest single day on record dumped 5.28 inches in February 1927, and a rare 12-inch snowfall in December 1915 remains the snowiest day ever logged here.
Summer is the dominant season here — late July averages a scorching 99° high, and highs stay in the 90s from June through September. The mildest time to visit is January through March, when highs hover in the mid-to-upper 60s and the area sees its only meaningful rainfall, peaking in the last week of February. By May the heat is building fast, and by July, Lake Elsinore is firmly in triple-digit territory.
