I've detected those beaches in the past and I've had no problems.My advice is to go for it. There's also Rest bay , Ogmore by sea , Southerndown, all available to detect on. Just be sensible fill in your holes and follow the code of conduct and all should be OK .Have fun and enjoy
Ogh yes we follow rules ect, we always fill in our holes and even take away the rubbish we come across, but I must admit the beaches at Porthcawl were very clean and it was a pleasure to detect them
Once again thank you for your advice, kind regards to you
Glad you had a lovely day detecting. Tides do come in fast especcially on spring tides which happen twice a month on full moon and new moon.If you are into beach detecting then get some tide tables or look online.
We are lucky in south Wales the spring tides when fully out occure at around the midday mark so its very convenient.I try to get on the beach about 2 hours before low water to follow the tide out that gives plenty of time for detecting before and after low water.Some tide tables only give time for high water so just add 6 hours 10 mins to get the approximate time for low water. Hope this helps, enjoy the beaches and the fresh air
