Quick Answer
The time of day significantly affects the effectiveness of shade in a desert environment, with the hottest part of the day typically between 11am and 3pm. During this time, even the most effective shade may not provide sufficient protection from the intense desert sun. It's crucial to plan for shade accordingly.
Choosing the Right Shade Design
When building a desert shelter, the design of the shade is critical to its effectiveness. A simple rule of thumb is to use a ratio of 1:1 for the length of the shade to the height. For example, if your shade is 8 feet long, it should be at least 8 feet tall to keep the sun off your head and shoulders. This design ensures that the sun’s rays are blocked, even when the sun is directly overhead.
Orientation and Positioning
The orientation and positioning of the shade are also crucial factors. In a desert environment, the sun moves from east to west, so it’s essential to position your shade accordingly. For optimal shade, face your shelter north-south, and ensure that your shade is positioned to block the direct sun during the hottest part of the day. This may involve adjusting the angle of the shade or using a canopy to provide additional protection.
Shading Strategies
In a desert environment, it’s not always possible to build a fixed structure for shade. In these situations, use natural shading strategies to your advantage. Look for areas with existing shade, such as under trees or rocky overhangs. You can also use a makeshift canopy or tarp to create shade. When creating shade, remember to leave some space between the shade and your body to allow for airflow and ventilation. This helps prevent heat buildup and reduces the risk of heat-related illnesses.
