Las Vegas wakes up dry and clear on Tuesday, May 19, 2026, with morning temperatures hovering near 61°F and relative humidity around 20 percent. Skies stay sunny through the day, with a high near 82°F and a north wind of 7 to 15 mph that could gust around 20 to 25 mph in exposed areas. A dry warming pattern is already in motion, pushing highs into the upper 80s by midweek and into the 90s by the holiday weekend, so anyone with outdoor plans will want to factor in both the gusty breeze today and steadily rising heat through Memorial Day.
Afternoon Winds And Warming Trend
Northerly to northeast winds will ramp up through the morning and into the afternoon, with gusts likely in the 20 to 25 knot range (about 23 to 29 mph) at Harry Reid International Airport and up to 30 to 35 knots (about 34 to 40 mph) in some outlying fields and canyon gaps. The high should land near 82°F today, Tuesday, May 19, 2026, then warm to around 88°F on Wednesday, May 20, 2026, and into the mid 90s by Thursday, May 21, 2026. Upper 90s are expected to return on Friday, May 22, 2026, and continue through Memorial Day, Monday, May 25, 2026, with conditions staying dry throughout the stretch, according to NWS Las Vegas.
Heat Safety And Cooling Centers
As high temperatures push into the upper 90s later in the week, residents without reliable air conditioning are urged to limit strenuous outdoor activity during the hottest afternoon hours and to check in on vulnerable neighbors and pets. Whenever possible, schedule outdoor work or events for the cooler morning or evening hours and carry water for longer outings. Local cooling center locations and detailed heat safety tips are available from the Southern Nevada Health District.
Airport travelers and outdoor event planners should expect some bumps from gusty winds this morning, so it is a good idea to allow extra time and check with your airline if you are flying later in the day. Otherwise, the week stays dry with a steady warm up, so plan on sunglasses, plenty of water, and a quick escape route to air conditioning if you will be outside during the afternoons.
