Las Vegas starts Monday clear and in the low 70s, but the afternoon will feel more like lingering summer than early October. The city is headed for a high near 96 degrees, with sunshine, very dry air and almost no chance of rain.

Sunny, Dry Heat Builds Through Friday

Temperatures remain stuck in the mid-to-upper 90s all week, with highs near 96 on Tuesday, 98 on Wednesday and Thursday, and 97 on Friday. Afternoon humidity is expected to fall into the teens, making shade, water and regular breaks especially important during the hottest part of the day.

The National Weather Service says above-normal temperatures will continue across the region through Friday. Las Vegas is expected to see minor to moderate heat risk, while Death Valley faces much more dangerous conditions and an Extreme Heat Warning through Friday evening.

Weekend Winds Bring The First Real Cooldown

Saturday should be mostly sunny with a high near 93, but winds will begin increasing from the south. By Sunday, the high drops to around 89 degrees and southwest winds are expected to reach 12 to 25 mph, giving the valley a noticeably breezier finish to the week.

Rain is still unlikely in Las Vegas, with only a small chance in the weekend forecast. The cooler, windier pattern is a substantive shift from the near-100-degree stretch outlined in Sunday's Hoodline forecast.

Best Windows For Outdoor Plans

Early mornings and evenings will be the more comfortable times for walks, workouts and outdoor errands this week. Midday plans will call for sunscreen, water and shade, especially Wednesday and Thursday when temperatures are forecast to come closest to 100 degrees.
