Weather in Mexico City in March

Prime time. March is about as good as Mexico City gets. Highs average 26.2 °C, lows 8.9 °C, and rain falls on 4 days — nothing in the month is working against you.

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

Rain falls on only 4 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: the day swings 17.3 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest March day reached 32.3 °C and the coldest night fell to -0.6 °C.

This is the volatile part. March rainfall has ranged from 1 mm to 67 mm across the twenty years measured — a 66 mm spread around an average of 15 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 4.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 50%.

How March sits in the year

The month is on the way up: 2.2 °C warmer than February, and April adds another 2.2 °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

12 hours of daylight, gaining 0.6 hours across the month. That is between Mexico City's extremes of 13.3 and 11 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 21.8 °C between the year's warmest afternoons and coldest nights. At 2240 m, altitude is doing as much work here as latitude: thinner air means fierce sun by day and heat that leaves the moment it sets. Within March itself the daily swing is 17.3 °C, so mornings and afternoons need different clothes.

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 Mexico City versus nearby

If Mexico City is one option among several, the nearby comparison is worth making. Santiago de Querétaro is close enough to be a coin toss — 2.5 °C warmer, 2 days less rain. Morelia is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: March is effectively as good as it gets here — 4 points behind December, which is inside the margin where the weather stops being the deciding factor and price starts being it.
