Your March weather guide
WarmWeather in Las Vegas in March
Las Vegas in March suits a trip built around warm afternoons, not guaranteed heat. Average daytime highs are 21°C, compared with 10.5°C in London, but nights fall to around 9°C.

Warm afternoons, chilly evenings
Light clothing can work during the warmer part of the day, but a jumper and jacket deserve space in your luggage. The coldest 10% of nights reach 3.5°C or lower, so the average night temperature does not tell the whole story. At the warmer end, 20% of days reach 25°C, making some afternoons feel more like summer than spring. Plan outdoor time around the mild daytime hours rather than assuming evenings will stay warm. March suits travellers who prefer warmth without persistent heat, though anyone expecting to wear summer clothing throughout the day and night is likely to find it too cool.
Plenty of sunshine, but keep plans flexible
With about 7.3 hours of sunshine a day, March gives you a useful amount of bright weather for spending time outdoors. Rain is possible, but about 3 rainy days makes it a relatively small part of the month rather than the main reason to hesitate. Keep an indoor option available instead of planning the whole trip around avoiding showers. Humidity averages 35%, so take water with you and consider lip balm or moisturiser if dry air bothers you. Sunglasses and sun protection still belong in your bag: mild air temperatures are not a reason to overlook the sun, particularly during the middle of the day.
