Weather in Mexicali in March

Prime time. If you get to pick your dates, March is the one. Highs average 27.9 °C, lows 12.1 °C, and rain falls on 3 days — nothing in the month is working against you.

March ranks 5 of 12 in Mexicali: past the worst of the year but short of November, which is the month to book if the dates are open.

Rain falls on only 3 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

Averages flatten a month, and this one hides a few things: 11 days top 30 °C — hot spells arrive, but they break; the day swings 15.8 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest March day reached 38.3 °C and the coldest night fell to 3.2 °C.

This is the volatile part. March rainfall has ranged from 0 mm to 53 mm across the twenty years measured — a 53 mm spread around an average of 13 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 8.6 km/h, so the temperature on the page is close to the temperature on your skin, and the air is dry at 39% humidity, which makes the heat far more bearable than the same figure somewhere humid — and dehydrates you faster than you expect.

How March sits in the year

The month is on the way up: 4 °C warmer than February, and April adds another 3.8 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

11.9 hours of daylight, gaining 1 hours across the month. That is between Mexicali's extremes of 14.3 and 10 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 36 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within March itself the daily swing is 15.8 °C, so mornings and afternoons need different clothes.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

March in Mexicali versus nearby

If Mexicali is one option among several, the nearby comparison is worth making. San Diego is close enough to be a coin toss — 5.8 °C cooler, 2 days more rain. Riverside is close enough to be a coin toss — 4.4 °C cooler, 2 days more rain.

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