Quick Answer
To signal for help on a beach, use bright colors, shiny objects, and smoke signals during the day, and mirror signals, flares, or a fire at night. Create visible patterns with rocks, seaweed, or shellfish to draw attention. Stay near the water's edge where rescuers are more likely to spot you.
Creating Visible Patterns
When stranded on a beach, it’s essential to create visible patterns that can be seen from a distance. Use rocks, shells, or other beach materials to create large, contrasting patterns. For example, create a series of large “X” marks, a large circle, or a long line of rocks or shells that stretch along the beach. This will help rescuers spot you from the air or from a distance.
Using Fire and Smoke Signals
During the day, use fire and smoke signals to draw attention to your location. Build a fire on the beach and add green leaves or wet wood to create a thick smoke. This will make your signal visible for miles. At night, use a fire as a beacon, and create a smoke signal by burning wet wood or other flammable materials.
Signaling with Shiny Objects and Mirrors
Use shiny objects, such as aluminum foil, a mirror, or a piece of glass, to create a reflective signal during the day. Hold the object at an angle to reflect sunlight towards any aircraft or boats in the area. At night, use a mirror to reflect the light from a fire or a flash light towards any rescuers. This will help them see your location and respond accordingly.
