Awning Wind Rating Checker

A retractable awning is a sail, not a roof. Most are rated to handle gusts of only about 17-30 mph (28-49 km/h) depending on their EN 13561 wind class, and none should stay out in a storm. Enter the forecast gust and your awning's details to get a clear answer.

What the wind classes mean

EN 13561, the European standard for external blinds and awnings, classifies awnings by the wind load they withstand in a test without damage or permanent deformation. The classes are commonly expressed as equivalent wind speeds on the Beaufort scale.

How the checker decides

  • It compares the gust, not the average wind, with your class speed. Damage happens in gusts.
  • Above 75% of the limit it returns "borderline": stay nearby, because gusts are irregular.
  • Projections over 10 ft are derated 5% per foot (up to 30%), a conservative allowance for the extra lever arm and fabric area compared with typical test sizes.
  • Heavy rain always means retract. Water pooling on fabric can load an awning far beyond its wind rating.
Retract Wise analysis: wind load scales with the square of wind speed. Going from 20 mph to 30 mph more than doubles the force on the fabric (1.5² = 2.25). That is why awnings that cope easily with a breezy afternoon fail suddenly in the first strong gust of a storm front.
Do not rely on manual checks alone: if the awning is ever left extended while nobody is home, fit a wind sensor. It is the cheapest insurance an awning owner can buy.

Frequently asked questions

What wind speed should I retract my awning at?

For a class 2 awning, retract at gusts approaching about 24 mph (38 km/h); for unknown ratings, about 12-15 mph. Retract earlier for long projections or exposed sites.

Can a retractable awning stay out in rain?

In light rain, only if pitched at about 14° or steeper so water runs off. Retract in heavy rain or storms.

Do wind sensors work in gusty conditions?

Vibration (motion) sensors on the front bar react to the awning's own movement, which tracks gusts well. Anemometer sensors measure wind at one spot and may miss gusts at the awning. Both need a sensible threshold.

Are cassette awnings more wind resistant?

Not necessarily while extended. The cassette protects the rolled fabric when closed. Extended wind resistance depends on arms, brackets and frame, which is what the wind class reflects.
