Death Valley Weather: Forecasts, Climate, and Current Conditions

By Jocelyn Pion · Data: National Park Service · ← Complete guide Death Valley

Death Valley is a desert basin 282 feet below sea level, surrounded by rocky walls that trap hot air and prevent it from circulating. Its climate is hyper-arid, with about 2 inches of precipitation a year, roughly what a French city might get in a single rainy month. The short answer: the park is beautiful and manageable from October through April, demanding starting in May, and potentially dangerous from June through September without serious preparation.

Death Valley Climate Month by Month

The figures below are for Furnace Creek, the reference station located in the heart of the basin. Higher-elevation areas, including Dantes View at 5,476 feet and Telescope Peak at 11,044 feet, record considerably lower temperatures.

June, July, and August bring barely 0.4 inches between them. This extreme dryness, combined with the basin's bowl-shaped topography, pushes heat to levels found nowhere else in North America.

The Climate Season by Season

Winter (December to February)

Winter is Death Valley's pleasant surprise. Days reach 63 to 73°F, while nights drop to around 39 to 45°F and can approach 32°F on the basin floor. The surrounding peaks, some rising above 9,843 feet, become snow-covered, creating a striking contrast with the salt flats below. Winter's low, golden light is ideal for photography. You can hike without worrying about the heat, as long as you bring a warm layer for sunset.

Spring (March to May)

This is the park's busiest season, and for good reason. In March and April, temperatures range from 54 to 93°F depending on the day. After a sufficiently wet winter, wildflowers such as desert gold, phacelia, and dune primrose can cover the Badwater Basin plain in a spectacular carpet of color. By mid-May, temperatures climb toward 104°F, signaling that the comfortable window is closing.

Summer (June to September)

Let's be direct: summer in Death Valley is not a typical time to visit. Temperatures on the basin floor regularly exceed 118°F in July. At night, they stay above 86°F. The surface of the Badwater Basin salt flats can reach 194°F. The NPS formally recommends avoiding all outdoor activity between 10 a.m. and 4 p.m. from April through October. From June through September, visitors who aren't acclimated to extreme heat should limit their movements to air-conditioned areas. The North American monsoon, from July to mid-September, sometimes brings short, violent downpours that trigger flash floods in the canyons.

Fall (October to November)

October marks the return of manageable conditions. Highs drop below 95°F in October and hover around 75°F in November. The sky is almost always blue, and visitation is much lighter than in spring. It's an excellent time to explore the Mesquite Flat Sand Dunes or the colorful Artists Palette without the pressure of the busiest hours.

Is Death Valley Hot or Cold? Records and Extremes

Both, with no middle ground. Death Valley holds the official world record for air temperature, 134.1°F recorded at Furnace Creek on July 10, 1913 (World Meteorological Organization). At the other extreme, the thermometer has dropped below 16°F at the same station during exceptionally cold winter nights. The difference between the absolute extremes exceeds 117°F at the same geographic location.

This is more than a trivia fact. Geography explains it all: the basin below sea level traps hot air like a pressure cooker, while the near-total lack of humidity prevents natural cooling at night. The dryness intensifies the heat far beyond what a thermometer alone can suggest.

What to Wear and Pack by Season

November through April. Wear layers you can add or remove: a T-shirt or lightweight shirt during the day, plus a fleece or jacket for evenings and cool mornings. Sturdy, closed-toe hiking shoes are essential because the terrain is rocky and the salt in the basin is hard on thin soles. Wear a hat and sunglasses year-round. Sun reflecting off the salt flats is more intense than it looks, even in January.

May through October. The rules change dramatically. Wear lightweight long sleeves for sun protection, not a tank top, and a wide-brimmed hat. Bring at least 4 liters of water per person for every hour of hiking, and more if temperatures exceed 104°F. Leave your vehicle only before 9 a.m. or after 6 p.m. Check tire pressure before heading out. Heat causes tires to expand and can lead to a blowout on overheated asphalt. Never leave a child or pet in a parked vehicle, even for a few minutes.

Warnings and Conditions to Watch

Extreme heat. When air temperatures exceed 100°F, the NPS issues a Heat Advisory. Above 109°F, it becomes an Excessive Heat Warning. Stay in air-conditioned spaces. The Furnace Creek visitor center and the Stovepipe Wells station are the two main refuges along the park's central corridor.

Flash floods. The park's topography turns even a light shower on the ridges into a torrent on the canyon floor. A flood can arrive under clear skies in the valley, fed by a storm you can't see 19 miles away. Before entering a narrow canyon, make sure the sky is clear across all the surrounding high ground. Check National Weather Service alerts for the area before every outing in a confined canyon.

Road closures. Secondary roads, including Artists Drive, Titus Canyon, and the salt roads toward Badwater Basin, are often closed after rain or extreme heat. Check road conditions in real time on the park's official website or in our complete Death Valley guide before planning an unpaved excursion.
