Climate, Weather & Temperatures
Best time to travel / Season
Big Bend is relatively uncrowded much of the year. Visitation is highest in March and April. The park is extremely crowded during spring break, which is usually the second and third week in March. Easter weekend, Thanksgiving weekend, and the week between Christmas and New Year's Day are also very busy. All lodging and campsites are usually full during these periods. Visitation is lowest in August and September.
In all seasons, whether walking, backpacking, or day hiking, follow these tips to conserve your internal water reserves:
Reduce your activity
During the warmest days, generally from May through August, avoid hiking in the lower elevations during the heat of the day — generally from 10:00 am to 6:00 pm.
Shade in the desert means the difference between excessive heat gain from the radiant sun and sheer comfort. In an emergency, a person resting in the shade will survive longer than someone exposed to the sun.
Don’t try to conserve the drinking water you have. Whether strolling in the Basin, or hiking the South Rim Trail, you must DRINK your available water. Carry plenty of drinking water — at least 1 gallon per person per day. Balance your food and water intake. Eat a salty snack every time you take a drink of water.
Reduce Alcohol and Caffeine Consume
Water is the best remedy for dehydration and listlessness. The diuretic effects of caffeine and alcohol can result in an accelerated loss of body water.
Protect Your Body
Our sensitive skin burns easily; it needs shade, sunscreen, sunglasses, a widebrimmed hat, and proper footwear. Dehydration is accelerated by exposed skin, so keep your clothing on. Wear long-sleeved, loose-fitting, light-colored clothes.
