Quick Answer
The hottest time of day to avoid while hiking is typically between 11am and 3pm when the sun is at its peak.
Understanding Heat Stress
When hiking in extreme heat, it’s essential to be aware of the risks of heat stress and heat stroke. These conditions can occur when the body is unable to cool itself effectively, leading to a rapid increase in body temperature. In hot desert environments, the sun’s intense radiation can cause the temperature to soar, making it crucial to take precautions during the hottest part of the day.
Timing Your Hike
To minimize the risk of heat-related illnesses, plan your hike to avoid the hottest part of the day. This typically occurs between 11am and 3pm when the sun is directly overhead. Consider starting your hike early in the morning or late in the afternoon when the temperature is slightly cooler. If you must hike during this period, take regular breaks in shaded areas to cool down and rehydrate.
Staying Safe
When hiking in extreme heat, it’s crucial to stay hydrated by drinking plenty of water throughout the day. Aim to drink at least 1 liter of water per hour of hiking, and consider using a hydration pack or water filter to ensure access to clean drinking water. Additionally, wear light-colored, loose-fitting clothing to reflect the sun’s radiation and allow for good airflow to help keep you cool.
