Las Vegas woke up clear, dry and already warming fast, with Harry Reid International Airport sitting near 73°F and humidity in the mid-teens. From there, the thermostat only goes one way. A strengthening ridge over the Desert Southwest is set to push afternoon highs to around 103°F today, and the heat is not leaving after the fireworks. Temperatures will stay hot through the Fourth of July weekend and intensify into next week, with overnight lows stuck in the upper 70s to mid-80s. If you have outdoor plans, treat the coming stretch like a full-on heat wave: carry water, find shade when you can, and have an air-conditioned backup plan.
Today's Forecast
The official outlook calls for a high near 103°F today under mostly sunny skies, then a warm night with a low around 78°F. Saturday, Independence Day, is expected to top out near 104°F. After that, highs climb into the upper 100s to low 110s by midweek, while nighttime lows barely dip, generally holding in the upper 70s to mid-80s. All of these numbers come from the National Weather Service.
Heat Risk And Fire Weather
Forecasters describe a steady warming trend that will push heat risk levels up across the region, with Moderate risk expected by Monday–Tuesday and pockets of Major risk by midweek. Each afternoon, breezes around 15–25 mph with occasional stronger gusts will kick up, which may feel nice for a moment but will also keep fire danger elevated and make long stretches outside more draining. The combination of very hot days and warm nights is especially hazardous for people without air conditioning and for anyone working outdoors. If you are grilling or using fireworks over the holiday, use extra caution around dry grass and brush.
Where To Cool Off
Clark County has activated daytime cooling stations across the valley for Monday–Wednesday, with recreation centers, libraries and community centers serving as escape valves from the heat. You can find the full list of locations and hours at Clark County. Many public libraries and community centers will be open with air conditioning during daytime hours, and transit providers have already posted schedules showing their summer service changes. If you are planning to be outside on Saturday, try to schedule the toughest activities for early morning or move them indoors.
Plan Ahead
Drink water often, even if you do not feel especially thirsty, and avoid heavy physical work during the peak afternoon heat. Check in on older neighbors and anyone who does not have air conditioning. Keep pets indoors as much as possible, and never leave a child, adult or animal in a parked vehicle, even for a short stop. For any backyard parties or park meetups, make a simple heat safety plan that includes shade, cooling breaks and plenty of fluids. This forecast will be updated as conditions change heading into the holiday weekend.
