Las Vegas started Sunday on the chilly side, with clear skies and temperatures hovering around 39°F at daybreak. That cold snap will not last long. Sunshine is expected to carry the valley into the upper 60s by this afternoon, with only a light north breeze and mostly blue skies. Enjoy the mild feel while you can, because the rest of the week is set to turn noticeably warmer.
Warming Trend Through Next Weekend
A broad ridge of high pressure is building in, ready to nudge temperatures a solid 8 to 12°F above what is typical for late February. Highs are forecast to jump from the upper 60s on Sunday into the upper 70s by Wednesday, then into the low 80s from Thursday, Feb. 26, through Saturday, Feb. 28, 2026. The National Weather Service in Las Vegas classifies this as a "Minor" HeatRisk for those days and recommends that outdoor workers and people who are especially sensitive to heat take it seriously and plan ahead, according to NWS Las Vegas.
What To Expect This Week
Daytime highs should land near 67°F on Sunday, around 72°F Monday, into the mid-70s Tuesday, and roughly 79°F on Wednesday, before topping out around 80 to 83°F by late next week. Overnight lows will mostly hold in the 40s to upper 50s, which should help the valley cool off a bit between those warmer afternoons. Winds stay on the quiet side for most neighborhoods, although the Colorado River corridor can still see stronger northerly gusts from time to time.
How To Plan Outdoors
For outdoor plans later in the week, mornings and evenings will be your best bet for more comfortable conditions. Keep water handy, pace activities, and watch for signs of overheating in older adults and children as temperatures climb. Clark County opens daytime cooling stations when excessive heat is officially declared - residents can call 2-1-1 or check local information for specific locations, according to Clark County.
