Conditions Through the Year

Sunshine is abundant most of the year. Spring is typically warm and pleasant and is the parks busiest season. Try to avoid mid-March (Spring Break) unless you have reservations for accommodations.

Summers are hot; temperatures vary greatly between the desert floor, which is often above 100 degrees Fahrenheit, and the Chisos Mountains, which are ten to twenty degrees cooler. June-August are the hottest months. Visitors should be familiar with heat safety. The rainy season runs from May through September, with locally heavy thunderstorms and some flash flooding. The rainy season can be a delightful time to visit since afternoon and evening rains often cool the desert.

Fall quickly melds into winter which is pleasantly mild and usually sunny, although periods of cloudy weather and freezing cold do occur. Snow is rare and generally light. Winter visitors must prepare for a variety of conditions. The holidays (Thanksgiving and Christmas breaks) are typically busy, so reservations for accommodations are highly recommended.

Elevation is Everything

Most weather forecasts highlight the temperature at Park Headquarters which lies at 3750 feet. Temperatures along the Rio Grande and low desert areas will be approximately 10 degrees hotter. Temps in the higher elevation Chisos Mountains average approximately 10 degrees cooler. Be prepared for this kind of variation during your trip.

Dress for the Weather

No matter the time of year, a wide-brimmed hat, comfortable clothing and sturdy walking shoes or boots are necessary for anyone planning to explore outdoors. Sunscreen is a must and hikers should always carry plenty of water; one gallon per person per day is recommended. Summer visitors should be aware of heat safety, such as wearing clothing that protects from the sun and avoiding activity during midday. Winter visitors should be prepared for any weather; temperatures vary from below freezing to above 80 degrees Fahrenheit .
