Weather in Los Angeles in March

United States · 20-year averages, March

Prime time. If you get to pick your dates, March is the one. Highs average 21.9 °C, lows 10.9 °C, and rain falls on 5 days — nothing in the month is working against you.

March ranks 4 of 12 in Los Angeles: past the worst of the year but short of May, which is the month to book if the dates are open.

Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest March day reached 32.5 °C and the coldest night fell to 3.8 °C, and the wettest single day dropped 60 mm — roughly 143% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 2 mm to 134 mm across the twenty years measured — a 132 mm spread around an average of 42 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 7.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 64%.

How March sits in the year

Temperatures hold steady either side: 20.1 °C in February, 21.9 here, 23.4 in April. Nothing about the timing within the month matters much.

Daylight in March

11.9 hours of daylight, gaining 1.1 hours across the month. That is between Los Angeles's extremes of 14.4 and 9.9 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 23 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

March in Los Angeles versus nearby

If Los Angeles is one option among several, the nearby comparison is worth making. Irvine is the weaker option in March — 4.5 °C cooler, the same number of rain days. Riverside is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: March is effectively as good as it gets here — 6 points behind May, which is inside the margin where the weather stops being the deciding factor and price starts being it.
