Guadalupe Mountains Weather: Forecasts, Climate, and Current Conditions

By David Sanchez · Data: National Park Service · ← Complete guide Guadalupe Mountains

Guadalupe Mountains National Park has a high-elevation desert climate with two defining features: strong winds year-round and wide temperature swings between day and night. In short, fall is the best time to hike, summer is hot with afternoon thunderstorms starting in July, spring is windy, and winter is cool but sunny.

Guadalupe Mountains Climate Month by Month

The table below reflects climate averages at the Pine Springs Visitor Center, at about 5,700 feet above sea level. On trails above 7,900 feet, expect temperatures about 11°F lower, along with generally stronger winds.

Climate Season by Season

Winter (December to February)

Winter days are mild and very sunny, with highs between 50 and 57°F at Pine Springs. Nights, however, regularly drop below freezing in the valley and much lower at higher elevations. Snow falls on the ridges every winter, but at lower elevations it usually lasts no more than 24 hours. The ever-present wind can make it feel 11°F or more colder. At a real temperature of 41°F with a strong gust, conditions can feel severely wintry. This is the park's quietest season, which is ideal if you enjoy uncrowded trails.

Spring (March to May)

March and April are the windiest months. Regular gusts top 56 mph, and documented peak gusts exceed 60 mph. It's spectacular from the valley floor, but less inviting at the summit of Guadalupe Peak. Heat builds gradually, with May days commonly reaching 82 to 86°F, and desert flowers begin appearing in April. If you're visiting in spring, bring a sturdy windbreaker and check conditions before heading onto exposed ridges.

Summer (June to September)

June is the driest and hottest month, with midday temperatures of 93 to 97°F, often cloudless skies, and almost no humidity. Things change in July when the Southwest monsoon arrives. Every afternoon brings brief but violent thunderstorms, with lightning and intense localized rainfall. Temperatures ease slightly and vegetation turns green again. In summer, start early and get off the summits before 1:30 p.m.

Fall (October to November)

In our view, October is the month to choose. Temperatures range from 48 to 79°F, skies are clear, and the park puts on its best display of color. When we visited, the bigtooth maples in McKittrick Canyon were glowing orange and red, a sight rarely seen in Texas. Crowds remain moderate, well below March and April levels. November turns colder quickly after midmonth, so bring your fleece and hat starting in the first half of the month.

Is Guadalupe Mountains Cold or Hot? Records and Extremes

Both, depending on the season and elevation. At Pine Springs, June days approach or exceed 97°F. Winter nights drop below 23°F at high elevations on the ridges. Wind is the variable you can't underestimate. With gusts of 60 mph or more, it can make it feel 10 to 15°F colder, in any season. Above 7,900 feet, especially on the Guadalupe Peak Trail, temperatures remain about 11°F lower than at the bottom of the park. Always bring an extra layer.

What to Wear at Guadalupe Mountains by Season

Summer (June to September): lightweight, breathable clothing, a wide-brimmed hat, SPF 50+ sunscreen, and sunglasses. Always pack a light rain jacket for afternoon monsoon storms. Get off the summits before 2 p.m.

Spring and fall: layers are essential. A breathable base layer, fleece, and waterproof windbreaker cover nearly every situation. For high-elevation camping, a sleeping bag rated for 32°F comfort or lower is necessary.

Winter: a durable windbreaker, hat, gloves, and waterproof hiking shoes. Snow is rare at low elevations, but nights in a tent are cold. Expect 23°F or lower on the ridges.

All seasons: at least 2 liters of water per person. The air is dry, elevation speeds up dehydration, and water resupply points are very rare outside Pine Springs.

Alerts and Conditions to Watch

Strong winds. The park may close ridge trails without notice during extreme gusts. Check conditions at the Pine Springs Visitor Center before setting out on exposed trails. The Guadalupe Mountains guide reports current closures.

Monsoon thunderstorms (July to September). Lightning is the main danger at high elevations. Don't stay on the summit of Guadalupe Peak after 1 p.m. during monsoon season. Storms form quickly, and there's nowhere to hide.

Salt Basin Dunes Road. The access road to these white sand dunes west of the park is clay-based. After even a small amount of rain, it becomes dangerous, even for four-wheel-drive vehicles. Check conditions before heading out.

Vehicles in the sun. In summer, the inside of a car parked in direct sun can top 140°F within minutes. Never leave a child or pet alone inside, even for “five minutes.”
