Las Vegas woke up clear and close to 70°F on Saturday, May 23, 2026, but the calm start is the warm-up act for a hot and thirsty holiday weekend. Forecasters are calling for an afternoon high near 97°F with very dry air and breezy southeast winds that could gust into the mid-20s, a combo that can make a few hours outside feel like a marathon without water.
Afternoon Heat And Winds
The valley’s forecast for Saturday, May 23, 2026, features a high near 97°F with southeast winds of 3 to 17 mph and gusts up to 25 mph, especially in the mid- to late afternoon, according to the National Weather Service. Afternoon relative humidity is expected to drop into the single digits to low teens, which means the air will be very dry and dehydration can set in quickly. If you are planning time on the Strip or at neighborhood events, try to schedule outdoor activities for the morning or evening and bring plenty of water and sun protection.
Memorial Day Weekend Outlook
Sunny, dry weather holds steady on Sunday, May 24, and Memorial Day Monday, May 25, with daytime highs in the mid-90s to upper-90s and overnight lows near 70°F. A Pacific low is expected to move into the Great Basin on Tuesday, May 26, which will bring stronger southerly to southwesterly winds and slightly cooler temperatures by midweek, with any precipitation mainly limited to higher terrain.
On The Water And Recreation
Southerly afternoon breezes will kick up choppy waves on Lake Mohave and other open water areas, so boaters should be ready with life jackets and cautious handling in gusty conditions, according to guidance from the Lake Mead National Recreation Area. Wind-driven waves can push pool toys and small craft into deeper water quickly, so it is smart to check marina updates and safety rules before heading out.
Weekend Tips
Plan outdoor time for the early morning or evening, drink plenty of water, and keep a close watch on kids and pets in the heat. Nights will stay warm, with low temperatures near 70°F, so indoor plans or shaded patios in the evening will likely feel more comfortable for most people.
