I was told I didn’t have to worry about the tide timing at Lower and Upper Rocks in Portmarnock. Not so. When I got there the tide was out. Next high tide for a swim is 10 ish. Too dark. I’m noticing a lot of conflicting information and naivety around the lovely Dublin swim spots. No wonder there is quite a high drowning rate. I could use some sea training myself. I didn’t fancy going down that ladder. When tide is in you just launch off the top. Its quite rocky. When the tide is in and its choppy you easily bang yourself off the rocks.
