Forecast

Monrovia has a Mediterranean climate, with hot, dry summers and mild, wetter winters. Most rain falls from November through March. Summers are usually sunny, with very little rain.

High pressure over the Pacific Ocean often brings clear skies and dry weather, especially in summer. In winter, low-pressure storms can move in from the Pacific and bring rain. Santa Ana winds may also bring very dry, warm, and gusty weather, mainly in fall and winter.

Monrovia sits near the San Gabriel Mountains and is about 15 miles from the Pacific Ocean. The mountains can block or redirect winds and make the northern parts of the city somewhat cooler. Ocean air may bring morning clouds or fog, but the mountains often help keep Monrovia warmer and drier than coastal cities.

Spring brings warmer days and less rain. Summer is the hottest and driest season. Fall stays warm but can have strong dry winds. Winter brings cooler temperatures, cloudy days, and most of the year’s rainfall. Snow almost never falls in the city, though it may appear on the nearby mountain peaks.
