Las Vegas gets a brief breather on Sunday, June 28, 2026, under clear skies and dry air. It is the coolest day in the current forecast stretch, but “coolest” is relative: highs still land near 94°F, with afternoon valley winds around 5–15 mph and gusts into the low 20s. Overnight lows hover near 72–75°F, so the heat lingers after dark. Those breezy, bone-dry conditions keep fire danger elevated across the region today.
Why It Is Cooler Today
A weak front slid through early Sunday, turning winds north-northwesterly and knocking a few degrees off recent highs. Forecasters expect breezy afternoons through the week, with valley winds of 5–15 mph and gusts near 21 mph this afternoon, increasing into the mid 20s and higher overnight in exposed spots. A Red Flag Warning remains in effect for Mohave County today, with the highest fire risk over higher terrain and the western Mojave. Temperatures are set to climb again later in the week, reaching the upper 90s to low triple digits by next weekend, according to NWS Las Vegas.
Fire Weather And Safety
Winds pick up this evening and overnight, with valley gusts commonly in the 20–25 mph range and gusts of 30–35 mph possible across Mohave County and higher elevations. Air remains extremely dry, with relative humidity dropping into the single digits in some areas and only weak recoveries overnight. It is a good day to skip open flames, hold off on grilling if possible, and keep a water bucket or fire extinguisher handy when using any spark-producing equipment.
Heat Returns After Brief Relief
The cooldown does not last. Highs rebound to near 95°F on Monday, June 29, then push into the upper 90s and low 100s by midweek. Forecasts call for highs near 101°F on Thursday, July 2, around 102°F on Friday, July 3, and a peak near 104°F on Saturday, July 4, making the holiday weekend the hottest stretch in this run. Outdoor work is best saved for the morning, and residents are urged to keep an eye on pets and older neighbors for any signs of heat stress.
Where To Cool Off
Clark County has daytime cooling stations open through June 28 at libraries, recreation centers and other community locations for anyone needing air-conditioned relief. For specific sites and hours, see Clark County, or call 2-1-1 for help finding a spot. If you or a neighbor are vulnerable to the heat, check in, drink plenty of water and avoid heavy outdoor activity in the hottest part of the day.
Residents should keep tabs on local forecasts and advisories, since winds and fire weather outlooks can change quickly. Weather spotters and community members are encouraged to report significant weather or impacts through normal channels and to follow public safety guidance throughout the week.
