I find weather forecasts to be generally good except for wind speed and direction,these things seem to change and the weather people can't forecast these changes.T any one time there is always wind somewhere in the UKWe always take ours down in winds forecast to be over 30mph, a figure
given to us on a site in Anglesy whose owner had this rule. We learnt the hard way in North Berwick when the wind got up over night and we took the awning down At 3am before it self destructed. We then stayed at Eye Kettleby in gales and a group of us took 8 awnings down of owners out for the day. Two were shredded the others survived our quick take down, the shower block became an awning superstore! Lots of grateful owners and two sad ones. The site owners were great, even phoning one vanner.
