Circuit breaker trips during windy weather

Agree with this

what tripswitch is tripping (is it the rcd)

have you an outside socket or cabling. Along with stormy windy weather comes driving rain which may be allowing moisture ingress somewhere.

I’d definitely be checking the outside sockets first

the cover may be secure but the seal may be allowing moisture in (they’re fiddly to install correctly)

have a good look at the black seal around the middle in daylight

Outside sockets would be better setup through double pole switches inside. Eliminates a lot of this messing in these situations.

I had something similar recently. It was a loose connection on the rcd in the end. After consulting a spark I took the cover of the fuse board to inspect the area only ( normally 4 plastic screws) look to see if any singing, burning or black. If there is any call a spark. I had my head light checking sockets, dishwasher as there were intermittent faults on certain sockets and randomly tripping.

Well you speculated that it might be a loose connection. Seems an unlikely cause of a tripping RCD, although Its hard to rule anything out but there would be a list from most to least likely.
