St Annes (Great between 2 hrs before and 2hrs after high tide, works best on 8.5m and above)
Ainsdale (Similar to St Annes although you need a permit)
New Brighton (Best on dropping tide, about 1.5hr after high tide)
Rhyl (Can't ride about 2hrs either side of high tide)
Llandudno West Shore (I think this is best between 2hrs before high tide and 2 hrs after)
Newborough (bit of a drive but mostly works at any tide state)
Rhosneigr (not sure best tides etc, only been there once)
