Excessive wind and rain are the leading causes of damage to awnings, and there is no definite rating for how much wind an awning can handle.
Light winds of less than 5 mph (8 kph) should not harm most awnings. However, wind gusts can rapidly reach very high speeds, and in extremely windy locations, an awning may not be suited for your application.
For a retractable awning, it is best to retract the awning before wind speeds reach the point of causing the awning to sway side to side or up and down. It is best to retract the awning when not in use regardless of the weather conditions.
