If you're planning a trip to Death Valley this week, here's something that should shape your plans. According to api.weather.gov and pressenterprise.com, an Extreme Heat Warning covers the area. It runs from October 4, 2026 at 11 a.m. until October 9, 2026 at 8 p.m. Pacific time. The alert was issued by the National Weather Service in Las Vegas (NWS Las Vegas NV), per api.weather.gov.
The affected zone is specific. The warning applies to Death Valley below 2,000 feet, meaning the valley floors, according to api.weather.gov. Those happen to be the park's most photographed spots, the ones where people most like to stop.
The numbers tell the story. According to api.weather.gov and pressenterprise.com, expect highs of up to 110°F during the day, and the night brings little relief, with a forecast low of 85°F. At that level, your body doesn't recover even after sunset, and the risk of heat-related illness climbs fast.
Here's what this means for you. Any outing in the low-lying areas between October 4 and 9 happens under extreme heat. We recommend timing your drives for the very first hours of the morning, never leaving your vehicle without a water supply, and saving the long walks for another time. The viewpoints you can reach by car are your best bet as long as the warning is active.
To locate these areas and plan a route suited to the season, lean on the Death Valley park guide, where we lay out the stops and the precautions. If the valley is part of a bigger trip, our road trip itinerary that passes through this park will help you shift the stop to a cooler time of day.
