May is the time of the year in Las Vegas when you start feeling the temperature rise and you realize that summer is just around the corner. Although it's getting warmer, the May heat in Vegas is comfortable, especially when compared to the city's midsummer temperatures. However, you may need a sweater at nighttime if you can't tolerate the crispness of the desert air. For the most part, May weather is about as perfect as the Las Vegas climate gets.

Las Vegas Weather in May

It's common in the desert for the day temperatures to be drastically different from night temperatures. However in May, daytime temperatures start to rise and the average high temperature is 88 degrees Fahrenheit (31 degrees Celsius). Nighttimes stay cool, however, and the average low temperature is 66 degrees Fahrenheit (19 degrees Celsius).

May and June are the least rainy months of the year. May's average rainfall is 0.12 inches for the month. Likewise, the humidity is really low, hovering at about 18 percent, so this really is a great month to spend a lot of time outdoors. The mid-afternoon sun and high temperatures can be dehydrating, so make sure you're drinking plenty of water, as you might work up a sweat if you're doing a lot of walking outside.

What to Pack

Since temperatures drop quickly at night, make sure to pack layers. The mornings and evenings might be brisk if you are walking along the Strip, so a long-sleeved shirt, sweatshirt, or hoodie will be good to have. You will be fine with T-shirts, shorts, and sandals during the day, but you might want a pair of pants and closed-toe shoes at night.
