Awaiting live data

Mullaghmore Head is rated from the NOAA GFS-Wave model sampled at the break itself; no NOAA wave buoy sits within 200 km, so the model is the only live source on this coast. It works on swell from WSW through NNW, best at 15–20 s. The first 5 days, the tide chart and every buoy's live readings and history are free to everyone; a free account adds the full 16-day wave and wind charts and custom swell alerts.
