Parasol Wind Guidance
As you may expect, our large garden parasols with the largest canopies have the strongest masts and arms – whereas smaller sizes do not need quite the same specification in order to achieve comparative robustness.
Our larger sizes (4m square and 4.5m x 3.5m) of premium model ‘Piazza’ have the most robust components. The main strength derives from:
Our smaller side-arm model the ‘Enzo’, with typical canopy sizes of 3m square or 3.5m x 2.5m rectangular, does not require all of these features in order to achieve comparative strength.
The ‘common sense guidance’ is to suggest that when the weather is so gusty and uncomfortable that you would not generally wish to be outside in those conditions – it may be wise to close and secure your umbrella.
& The Beaufort Scale
The Beaufort Scale can be helpful as a guide – but a Scale number can seldom give a definitive assurance of performance for any single parasol in any particular location.
For instance, performance in wind will surely vary;
Scale 1 - 5
Winds up to 38 kph / 24 mph
You should expect your Poggesi umbrella to cope well and without concern. Please remember though – do not leave it open while away from home overnight (and of course on longer trips). If in doubt, just close the umbrella. It only takes a minute, and conditions can significantly change in our increasingly volatile climate.
Winds up to 49 kph / 30 mph
“Large branches in motion; whistling heard in telegraph wires; (handheld) umbrellas used with difficulty”.
In such winds you would most likely be only keeping the umbrella open for ‘convenience’ such as keeping cushions dry. When the main canopy starts to sway you would be wise to close the umbrella. However, if your umbrella is in an enclosed / protected position you should use your experience to determine your action.
Winds up to 61 kph / 40 mph
“High wind / near gale. Whole trees in motion; inconvenience felt when walking against the wind”.
In these winds Poggesi UK has a simple message for our clients – while most likely your umbrella will be safe and remain un-damaged, these conditions will almost certainly be putting pressure on components, and clients whose umbrellas are in areas known for gusty / exposed / elevated conditions should certainly close them to prevent damage or injury.
Scale 8 - 9
Gales strong / severe gales
“winds generally impeding process” and references “possible structural damage / chimney pots falling” surely your umbrella should be closed and protected by putting on the supplied storage bag.
"Seldom experienced inland; trees uprooted; considerable structural damage".
Now referred to as ‘named storms’, such as Desmond. Your umbrella should certainly be closed as early as possible.
Scale 11 - 12
Violent storm / hurricane
"Very rarely experienced; accompanied by widespread damage".
At these levels you would certainly have your umbrella closed and possibly even removed from the base. Failure to do so could certainly lead to your umbrella being damaged.
Positioning the umbrella in exposed locations.
At Poggesi UK we take pride in offering a complimentary site survey, during which we can discuss all aspects of your parasol including where to position the base. When considering the base position, we look at;
If we deem the space to be elevated and / or exposed, we may well recommend that the parasol be positioned facing towards the building. The umbrella is at its strongest when facing away from the prevailing wind – as in the image above.
