Hey Robin,
The Greater Dublin area seems a bit thin on the ground with them just lately but I'd say the bigger tides coming will help, however Wexford seems alive with them at the minute, and some turning up on the Wicklow beaches but not with any great consistency.
Give me a bell if you want a bit more help, or maybe even get out for a session over the next week or so - if you can get a pass that is
Regards
Mark
