Quick Answer
Choose a location with natural shade from trees, rocks, or hills, avoiding direct sunlight between 10am and 4pm when possible. Consider the orientation of the sun and the time of year for maximum shade effectiveness. Position your shelter to block out harsh sunlight.
Choosing the Right Orientation
When selecting a location for maximum shade effectiveness, consider the direction the sun rises and sets. In the Northern Hemisphere, the sun typically rises in the east and sets in the west. Position your shelter to block out direct sunlight from the east in the morning and west in the afternoon. For a desert shelter, a north-south orientation is ideal, as it allows for shade from the south-facing sun during the hottest part of the day.
Analyzing the Topography
Study the surrounding topography to identify natural features that can provide shade. Look for trees, rocks, and hills that can block out direct sunlight. Consider the height and angle of these features, as they can significantly impact the amount of shade provided. For example, a tall tree with a dense canopy can provide more shade than a shorter tree with sparse foliage. Aim for a location with a combination of natural features that can provide year-round shade.
Measuring the Shade Index
To quantify the effectiveness of your chosen location, calculate the shade index by measuring the percentage of direct sunlight blocked by the surrounding features. Use a tool such as a solar compass or a sun shadow stick to measure the angle and length of shadows. Compare your results to a standard shade index chart to determine the effectiveness of your location. Aim for a shade index of 80% or higher to ensure maximum shade effectiveness.
