The National Weather Service has extended its Extreme Heat Warning for the Las Vegas Valley through 8 p.m. Saturday, marking the second extension of a warning that was originally set to expire days ago. Afternoon highs are expected to stay at or above 110 degrees through the weekend, keeping outdoor conditions dangerous for dogs and their owners.

If the streak holds through Sunday, Las Vegas will have logged 11 straight days at or above 110 degrees, tying a record set in July 2024. Sunday’s high of 113 was already the fourth day in a row in that range.

Forecast highs include 113 on Tuesday, 112 on Wednesday and Thursday, and another climb to 113 on Friday and Saturday before a slight dip to around 111 on Sunday. Overnight lows are only falling into the mid-80s to low 90s, leaving little relief after dark.

Some of the coming days are within a few degrees of daily heat records for early August, including a 116-degree mark for August 3 and a 114-degree record for August 4. Harry Reid International Airport already hit 115 degrees on August 1, the hottest day of the year so far.

Heat remains the deadliest weather-related killer in the country, causing more deaths nationally than hurricanes, tornadoes, and floods combined, reports 8 News Now. Dogs are especially vulnerable during stretches like this one, since they cool themselves mainly through panting and can overheat within minutes on hot pavement or in parked cars.

Dog Friendly Las Vegas has been tracking this heat wave since it began in late July, including safety tips for keeping dogs cool during the earlier round of the Extreme Heat Warning that started July 30. The seven-second pavement test still applies.

Press the back of your hand to the asphalt, and if you cannot hold it there, it is too hot for paws.

Walking dogs before 7 a.m. or after 8 p.m., carrying water on every outing, and never leaving a dog in a parked vehicle remain the most important precautions. Clark County continues to operate cooling stations at community centers and libraries across the valley for residents who need a break from the heat.
