Las Vegas is starting Sunday under clear skies and comfortable low 70s, but the cooldown will not last long. This afternoon is expected to spike to a hot 95°F, and that is just the warmup act for the week ahead. Temperatures climb into the triple digits early next week, with highs near 100°F on Monday and topping out around 102 to 103°F on Tuesday and Wednesday. Skies stay dry, overnight lows hang in the low to mid 70s, humidity stays low, and afternoons turn breezy at times. If you have outdoor plans, try to tackle the heavy lifting in the morning or evening and check in on anyone who may not have solid access to air conditioning.
Forecast Details
Sunny weather is locked in through midweek, with daily highs rising from the mid 90s on Sunday to the low 100s by Tuesday and Wednesday. Rain chances are essentially zero, and forecasters say there are currently no heat watches or warnings in effect. These forecast details are reported by the National Weather Service.
Heat Safety And Local Resources
Even without official heat alerts, this stretch brings a minor to moderate heat risk for people who work outdoors or sleep without air conditioning. Clark County maintains a Stay Cool page and a rotating list of cooling stations, so use it to find an air conditioned place to ride out the hottest part of the day if you need it. Basic precautions still matter: drink plenty of water, avoid strenuous activity in the mid afternoon, never leave children or pets in parked cars, and check on older neighbors. For local resources, see Clark County.
Looking Ahead
By late next week a broad trough approaching the western United States may nudge stronger south to southwest winds into the region, with forecasters putting the chances for impactful winds at roughly 30 to 60 percent across much of southern Nevada. That system should trim a few degrees off afternoon highs after midweek, although rain chances remain below 10 percent. If you are planning outdoor projects or travel, it is worth keeping an eye on updated forecasts later in the week. The guidance and discussion are summarized by the National Weather Service.
