Quick Answer
It is generally safe to use a tarp in windy conditions if properly setup and secured, but high winds can be a threat to the structural integrity of the tarp.
Wind Resistance and Tarp Setup
When setting up a tarp in windy conditions, consider anchoring it to multiple trees or secure points, spaced between 6-12 feet apart. This will help distribute the force of the wind and prevent the tarp from being torn loose. Use cordage like paracord or rope that can withstand the wind and tarp weight, and consider adding additional anchoring points for extra security.
Tarp Shape and Wind Direction
A diamond or hexagonal tarp shape is more wind-resistant than a square or rectangular shape, as it presents less surface area to the wind. If the wind direction is expected to be strong, consider anchoring the tarp with the wind direction in mind, securing the tarp to the ground or trees at a 45-degree angle to the wind direction. This will help reduce the force of the wind on the tarp.
Tarp Material and Wind Load
Choose a tarp made from a durable, water-resistant material like nylon or polyester that can withstand wind loads up to 30-40 mph. Be aware that high winds can still cause the tarp to rip or tear, especially if it is not properly secured. Consider using a tarp with a reinforced stress point or a reinforced edge to increase its wind resistance.
