Thanks Marineboy
You've reminded me that it's time to buy a 2010 tide tables booklet.
I try to make every low spring tide, and yesterday braved winds gusting to force 8 and horizontal stinging rain to follow the tide down to a modest but rewarding 1.3 m
I live on Guernsey. We have a brilliant tidal range of about 10m and a great variety of marine organisms. Quite a lot of unusual warm water creatures arriving in the summer too.
The oddest thing I ever found was a wild boar. I was going to post it here but my daughter said it was too gross

I'm not squeamish myself so I took her word for it. I'd love to know how it got washed up on one of our northwest beaches though, because they aren't native here
Most parts of the islands are great for rock pooling, and I've been doing it since I was a kid, but Herm island is the best place i know. I'm still convalescing so could only make it out to the Lihou island this time. In practice a bit too rocky for a good root around. The east coast of Guernsey from St Peter Port up to Richmond Corner is superb at the low springs. I generally end up taking hundreds of photos each time. Always something new to try and ID.
I'm never happier than when out alone beach-combing or rock pooling on some deserted shoreline. Nice to find others who share that pleasure
Cheers,
