Weather in Laredo in March

Prime time. If you get to pick your dates, March is the one. Highs average 28.8 °C, lows 14.1 °C, and rain falls on 5 days — nothing in the month is working against you.

March ranks 5 of 12 in Laredo: past the worst of the year but short of February, 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. Pack for 28.8 °C days and 14.1 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 14 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest March day reached 39.9 °C and the coldest night fell to -2.4 °C, and the wettest single day dropped 44 mm — roughly 119% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 3 mm to 116 mm across the twenty years measured — a 113 mm spread around an average of 37 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 12.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 60%.

How March sits in the year

The month is on the way up: 4.6 °C warmer than February, and April adds another 4.3 °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 0.8 hours across the month. That is between Laredo's extremes of 13.9 and 10.4 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 29.9 °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 14.7 °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 Laredo versus nearby

If Laredo is one option among several, the nearby comparison is worth making. Corpus Christi is close enough to be a coin toss — 3.3 °C cooler, 1 day more rain. Monterrey is the weaker option in March — 3.2 °C warmer, the same number of rain days.

So: March works, with February the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
