Conditions at Lahinch in August
August: Summer Swell With a Subtle Pulse
August is very similar to July, with the average swell at around 4ft (1.2m) and a low period of 8.9s. The deep summer pattern still holds, yet there are hints of autumn: occasional tropical or early extratropical systems in the Atlantic can send welcome pulses of slightly longer-period swell. W swells dominate at 43.5%, and WSW at 18.7%, so there is always something at Lahinch - but size is small, with most waves in the 1-4ft range. Ideal winds drop to 18%, and the prevailing WSW-W flow creates onshore conditions much of the time. That said, the water is at its warmest, 16.7°C, and the combination of decent sandbars and forgiving waves can make it a fun time for beginners. Keep expectations low and the quiver flexible; early morning again offers the best chance for glass.
