Awnings & Umbrellas that can withstand strong winds
A common question we ask when discussing shading solutions, like awnings and umbrellas, with customers is how windy is the location of the shade. This is an important factor when determining the right shade. An incorrect shading solution might get damaged easily. So how do you decide? What is the right Solution? Let us explain.
A question of wind
An easy way to measure how much wind is at a location is by using anemometer. This measures the windspeed. It’s very useful in determining what is suitable for the location. Windspeed is generally greater by the sea and on higher floors. Also buildings sometimes funnel the air flow creating very windy locations inland. These points should always be considered when deciding on the shading choice.
This video shows the forces applied on centre pole Glatz umbrellas when installed in a wind tunnel. As you can see the models can withstand very high windspeeds. These umbrellas are not installed with bases but are bolted to the surface of the windtunnel.
What is the right shading solution for windy locations?
This depends on the type of shade required and its purpose. If a customer wants a pool umbrella then a centre pole umbrella either bolted down or with a heavy base should be considered. Avoid cantilever umbrellas unless they are strong models like the Sirius umbrella with heavy bases.
For shading a larger terrace then consider large giant umbrellas. Think 400×400 up to 600×600 or 700cm dia. Alternatively one should consider pergolas that are bolted down or shade Sails. These can withstand strong winds without problems.
For the beach, one needs to consider that the shade might go unmonitored for large parts of the day meaning that the shade cannot be closed in time. Centre pole umbrellas with a heavy base should be consider or a fixed non closing umbrella like a thatch umbrella. This umbrella is set in to the sand in concrete and can withstand the strong gusts without getting blown over.
The wind table
| Type of umbrella | Size | Approximate wind speed |
|---|---|---|
| Fortino Centre Pole umbrella | 300cm dia | 60km/h |
| Palazzo Style Giant Umbrella | 400×400 | 80km/h |
| Art Monoblock Awning | 400×300 | 38 Km/H |
| Sirius Cantilever Umbrella | 300×300 | 60 Km/H |
| Soliday S Shade Sail | 500×400 | 30-40 Km/H |
The above wind table are the approximate guides for for the maximum windspeed a shade can withstand. Note for umbrellas, this is when they are fixed to the floor with a ground anchorage. For the awning and shade sail, additional wind sensors can be installed which will close the system when the windspeed is reached.

What are the type of umbrellas and the wind speed it can take?
Fortino Centre Pole umbrella – 60km/h
Palazzo Style Giant Umbrella – 80km/h
Art Monoblock Awning – 38 Km/H
Sirius Cantilever Umbrella – 60 Km/H
Soliday S Shade Sail – 30-40 Km/H
Which is the best shading for beach areas?
For beaches, Centre pole umbrellas with a heavy base should be considered or a fixed non closing umbrella like a thatch umbrella. This umbrella is set in to the sand in concrete and can withstand the strong gusts without getting blown over.
What if the windspeed is higher than the shade can withstand?
For the awning and shade sail, wind sensors can be installed which will close the system when the windspeed is reached.
