Las Vegas woke up to clear skies and classic Memorial Day heat on Monday, May 25, 2026, with early readings in the upper 60s and the valley headed for another hot afternoon. The holiday high is expected to land near 97°F, with only modest overnight relief as temperatures dip into the low 70s. That means the Strip and nearby neighborhoods stay plenty warm well after sunset, so if you are joining the holiday crowds, plan on regular water and shade breaks and push the heavy lifting to the cooler morning or evening hours.
Afternoon Heat and Memorial Day Plans
Sunshine will rule the sky today, driving highs to around 97°F before slowly easing back into the mid 90s later in the afternoon as light south to southeast breezes pick up. The low humidity will keep the heat feeling dry instead of swampy, but it is still a tough setup for seniors, those with health issues, and anyone working or playing outside too long. Check on vulnerable neighbors, keep kids and pets out of parked cars, and treat the strong afternoon sun like the main event it is.
Gusty Winds Return Tuesday
On Tuesday, a Pacific trough is expected to push inland and kick up gusty southwesterly winds across the Mojave Desert and southern Great Basin. A Wind Advisory is in effect for parts of the western Mojave Desert, and forecasters say exposed corridors could see gusts into the 30s, with even higher readings possible in outlying areas. It is a good day to secure patio furniture, tie down canopies, and prepare for choppy conditions on Lake Mohave, according to the National Weather Service Las Vegas.
Cooler, Breezier Midweek
Temperatures should drop by roughly 6 to 12 degrees from Tuesday into Wednesday as the low pressure system hangs around the region, trimming the edge off the heat. Light showers are possible mainly over higher terrain, and a rumble of thunder cannot be ruled out. Breezy conditions are expected to linger into Thursday before the pattern settles down and highs trend back up into the weekend.
How To Plan
For holiday plans, front-load outdoor time into the morning and shift the rest to the evening when the sun is lower. Lock down any outdoor gear before Tuesday’s gusts arrive, and boaters on the Colorado River corridor should expect rougher water and plan accordingly.
