Parasol Wind Test: Failure Speeds for 25 UK Models & Base Weights
A parasol is a sail, and in British gardens it fails at the base rather than in the fabric. This analysis by Furniture in Fashion sets out the physics that decides the outcome: wind load rises with the square of wind speed, canopy area multiplies it, and the height of the canopy above the base turns force into an overturning moment. It explains why cantilever designs load their bases even in still air, how to read wind strength using the Beaufort descriptions the Met Office applies, and why passing a pole through a dining table into a base below is the most effective free stability measure available. The report also covers siting, including the gaps, corners and raised terraces that accelerate airflow in UK gardens. No wind testing was carried out for this report and no model by model failure speeds are reported, because none were measured and no verifiable published test exists. Manufacturer base guidance for a specific parasol always takes precedence over the general principles given here....
