Las Vegas Temperatures to Climb Into the 90s by This Weekend

A steady warming trend will push valley temperatures from the upper 70s to 90 degrees between Tuesday and Sunday.

Las Vegas is entering a week-long warming trend that will carry temperatures from a mild 78 degrees on Tuesday to a high of 90 degrees by Sunday, according to the latest forecast. Dry conditions will dominate most of the valley through the week, with only a slight chance of isolated showers confined to mountain areas on Thursday, and increasing wind gusts expected as the weekend approaches.

Mild Start Gives Way to Rising Temperatures

Tuesday kicks off the week with clear to mostly sunny skies and a comfortable high of 78 degrees across the Las Vegas Valley. Light winds and dry air are expected to make for pleasant spring conditions as high pressure begins to build over the region.

Temperatures continue their climb on Wednesday, reaching a forecast high of 82 degrees under clear to mostly sunny skies. Clouds are expected to increase overnight as a weather system passes south of the region, but Las Vegas itself is forecast to remain dry throughout the day.

Thursday Brings Breezy Conditions and a Mountain Shower Chance

Thursday's forecast calls for a high of 84 degrees with some clouds moving in and out of the valley. A slight chance of isolated showers develops, though that precipitation risk is primarily limited to mountain areas, with most of the Las Vegas Valley expected to stay dry.

Wind gusts are forecast to increase through Thursday afternoon, reaching 20 to 25 mph. Residents heading into higher elevations should be aware of the possibility of showers during that period.

Weekend Heat Builds With Strengthening Winds

Friday continues the warming trend with sunny skies and a high of 86 degrees. High pressure is forecast to strengthen over the region, allowing temperatures to climb further. A lingering breeze of 25 to 30 mph is expected through the day.

Saturday pushes the forecast high to 89 degrees under mostly sunny skies, with calmer wind conditions compared to the days surrounding it. Warmer air is expected to settle firmly across the region heading into the final day of the weekend.

Sunday rounds out the week with a forecast high of 90 degrees, though mostly cloudy skies are expected. Wind will strengthen during the day, with gusts reaching 30 to 35 mph, creating breezy conditions across the valley. The combination of heat and wind will be notable for residents spending time outdoors.

Why it matters
