Updated Sun 11 Oct, 19:36

Rivermouth peaks over sand at the south end of a long beach, with a right point nearby. Only westerly or big north-westerly swells get through the gap between Ireland and Islay, so it’s fickle and often weak. Best at mid tide in an easterly. Fine for all levels on a mid-length or longboard when it’s small, but not for beginners once it picks up. Strong rips and no lifeguards.
