Hey MaMoTTaT your area's the wettest and my town is the windiest lol.
On the school run I have to walk past a park that sits virtually right at the bottom of those downs(westerly side), when you reach the park if its a gusty day,and a westerly wind it can almost knock you off your feet.
Its not a good idea to use a brolly here if there's even a small breeze.
