Porth Neigwl is a beach break in Lleyn Peninsula, North Wales, UK, with peaks that run both left and right.
Porth Neigwl picks up swell from the S round to the WSW, and it's best when it's coming straight out of the SSW. It starts working at around 1m and handles up to about 2.5m, with the sweet spot around 1.7 to 2.1m. Period matters too: aim for 12s or longer, as anything under 8s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
A NNE wind is dead offshore at Porth Neigwl, and anything from the N round to the ENE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
Porth Neigwl is at its best around low tide.
The most reliable run of swell at Porth Neigwl comes Sep to Feb. There's a second window in Mar to May too.
The water at Porth Neigwl averages around 11°C, so you'll want a 5/4mm with boots. It shifts a few degrees through the year, so check the season before you pack.
It's more of an intermediate wave, rated 5/10 for difficulty, so newer surfers are best off sticking to the smaller days. Expect a moderate crowd (6/10) when it's on. Wedgy left at south end over rocky bottom. Strong rips possible.
