How much wind can a Shade Sail withstand? 0416 285 656 Our residential shade sails are typically designed to withstand winds of 50 knots (92.6 kph or 57.54 mph) provided they are properly installed and tensioned. We recommend taking your shade sail down if winds in your area are going to exceed this rating (ie, cyclone, hurricane or typhoon). Fax: 02 9820 5565 |
