Quick Answer
Choose a shade angle that minimizes direct sunlight exposure, ideally between 30 and 60 degrees from the horizon, to create a cooler and safer desert shelter. This angle reduces the sun's intensity and minimizes the risk of solar radiation. It also helps to prevent sandstorms and provides a more stable shelter.
Determining the Optimal Shade Angle
To choose the right shade angle for your desert shelter, consider the time of day and the season. During peak summer months, the sun is highest in the sky, usually between 9 am and 3 pm. In this period, aim for a shade angle between 45 and 55 degrees from the horizon to minimize direct sunlight exposure.
Calculating the Shade Angle
Use a stick or a makeshift compass to calculate the shade angle. Insert the stick into the ground at an angle and mark the spot where it touches the ground. Then, measure the angle using a protractor or a makeshift angle-measuring device. Alternatively, use the sun’s shadow to estimate the angle. Measure the length of the shadow and use a rough estimate of 1:15 as the ratio of the object’s height to the shadow’s length.
Creating a Stable Shelter
Once you have determined the optimal shade angle, create a stable shelter using natural materials such as rocks, branches, and sand. Dig a shallow trench and place a layer of rocks at the bottom to provide additional support. Then, arrange branches in a lattice pattern to create a sturdy structure. Cover the shelter with a layer of sand or branches to provide additional protection from the elements.
