Las Vegas is kicking off the weekend under clear skies and a fast warm-up this Saturday, March 14, with temperatures already near 61°F and humidity down in the low 20s. Mostly sunny conditions will help the mercury race into the upper 80s this afternoon, with forecasters pegging the high near 89°F. That puts today among the warmest March afternoons in recent weeks. With the dry air, the sun will feel a bit like a spotlight, so if you are outside for more than a few minutes, bring water and plan for extra time in the shade.
Heat Builds Through The Week
The heat does not back off after today. Temperatures climb through next week, with forecast highs reaching the low 90s by Tuesday, March 17, and pushing into the mid-90s by Wednesday, March 18. According to the National Weather Service, a strengthening high-pressure ridge could send readings to around 20 degrees above normal by midweek, with some lower-elevation spots flirting with 100°F by Friday, March 20. An earlier warm spell was covered on March 1; this update zeroes in on the sustained warming and lake-wind concerns that could reshape weekend outdoor plans.
Lake Wind Advisory For The Colorado River Valley
Forecasters are also flagging a Lake Wind Advisory for the Colorado River Valley from 8 a.m. Sunday, March 15 through 8 p.m. Monday, March 16, as north winds funnel down the river corridor. Expect choppy 1 to 3 foot waves on Lake Mead, Lake Mohave and Lake Havasu, creating hazardous conditions for small boats, with periods of blowing dust possible along the river valley. If you are heading to the lakes this weekend, secure loose gear, wear a life jacket and think hard about postponing small-craft outings until the winds back off.
Plan Ahead
To ride out the heat, try to shift strenuous outdoor chores to the morning or evening through next week and keep extra water, sun protection and shade close at hand. The combination of high temperatures and low humidity can make the heat feel more intense than the thermometer suggests. Older adults, very young children and anyone not used to desert heat should skip the midday exertion and firm up plans for cooling and hydration. This briefing will be updated if advisories change, and travelers or event-goers should check the latest official forecast before heading out.
