Las Vegas eases into Sunday, March 15 with plenty of sunshine, bone-dry air, and temperatures in the low 70s at Harry Reid International Airport, headed for a high near 80°F this afternoon. North-northeast breezes are already stirring across the valley, and with dew points stuck in the 20s°F, it will feel crisp and very dry even as the mercury climbs.
Afternoon Winds and Lake Conditions
Those north-northeast winds will pick up through the afternoon, generally around 7 to 12 mph with gusts as high as 18 mph across the valley. Along the Colorado River Valley, the wind will hit harder, 15 to 25 mph with peak gusts near 40 mph. That setup will kick up choppy 1 to 3 foot waves on Lake Mohave and Lake Havasu, so small craft should use caution and anything not nailed down outdoors should be secured.
Record-Threatening Heat Later This Week
An Extreme Heat Watch is in effect for the Las Vegas Valley and southern Clark County from Thursday morning through Friday evening, with highs expected to surge into the upper 90s and around 100°F later in the week. Those numbers put long-standing March records on the hot seat and raise the risk of heat-related illnesses. The National Weather Service Las Vegas advises limiting outdoor exertion during the middle of the day and checking in on neighbors who might be especially vulnerable.
Where To Find Cooling Help
Clark County operates daytime cooling locations and other heat-relief resources during extreme heat events. If you need a cool place or assistance, you can find the county’s list of centers and hours online. Residents are urged to stay hydrated, never leave children or pets in vehicles, and plan outdoor activities for the cooler morning or evening hours. More local resources are available from Clark County.
