In reply to Owen W-G:
I'd probably avoid rough farm sites but otherwise anywhere along the Mendip escarpment should be fine (Cheddar / Priddy / Wells area). The flooding you've seen on the news is further south on the levels.
Brean is a suntrap and should be lovely tomorrow. Split Rock should hopefully be dry enough but you can always nip over to Cheddar instead, it's only fifteen minutes away.
