About

March is when Las Vegas leaves winter behind. The 1991-2020 normals for Harry Reid International Airport give an average high of 71.1°F and an average low of 50.5°F, roughly eight degrees warmer than February by day. Warm spells are common: a normal March has 5.4 days of 80°F or warmer. March 2026 was exceptional, setting the month's record high of 98°F on March 25 and, according to the National Weather Service, the most March days of 90°F or above on record, 12.

Cold snaps still happen. The coldest March reading on record is 19°F, from 1939, though a normal March has almost no freezing nights at the airport. Rain is light, with a normal of 0.42 inches for the month.

The National Weather Service singles out spring and fall as the months usually considered most ideal in Las Vegas, with one caveat: wind. Strong winds tied to passing storms are most common in the spring months, and while winds over 50 mph are infrequent, they bring blowing dust and sand when they arrive. Sharp temperature swings from one day to the next are also typical of the season.

What to expect

College basketball comes first. The 2027 Mountain West basketball championships are at the Thomas & Mack Center from March 7 to 13, with the women's tournament on March 7-10 and the men's on March 10-13, according to the conference's bracket announcement as published by member school UC Davis.

NASCAR follows. Las Vegas Motor Speedway lists the Pennzoil 400 NASCAR Cup Series race for March 21, 2027, with a NASCAR O'Reilly Auto Parts Series race the day before, March 20.

Clocks change too: daylight saving time begins at 2 a.m. on the second Sunday in March, which NIST lists as March 8 in 2026. Evenings stay light later from then on.

Windy days are part of spring. The NWS says strong winds are most common in the spring months and can bring blowing dust.
Start sun protection now. Days are longer and warmer; SNHD advises sunscreen with a high SPF and a hat outdoors in warm weather.
Remember the clock change: daylight saving time starts at 2 a.m. on the second Sunday in March.
