I was looking for a site that would show which beaches are Red Flagged. They used to do it here http://www.bviddm.com/beach-safety-red-flags-are-flying-at-10-beaches/

Red Flags at The Baths signal no dinghy arrivals, though you can still approach from land via Top of the Baths.

Caution- The link is to a page from Mar 11, 2016, which appears to be the last time it was updated. Anyone know if this information is available elsewhere realtime?
