The Lowdown
Right then, let’s have a look at what’s coming down the line for Portreath Harbour Wall.
To be honest, it’s a pretty grim stretch ahead. We’ve got a full 16-day window here, but there’s barely a whisper of a decent wave. The first few days are a write-off with poor surf conditions and negligible energy, so you’re looking at a long gap until we get a sniff of something half-rideable. The only flicker of hope comes around Wednesday the 12th and into the first few days of the second week, but it’s not exactly going to have you racing down the cliff path.
For the stand-out, if you can call it that, it’s the Wednesday afternoon session on the 12th of August. The wind swings offshore from the ESE at 12 mph, which will clean things right up for Portreath Harbour Wall (United Kingdom). We’ll see a weak 3 ft swell from the west, with a mediocre 9-second period. The combined energy is a modest 136 (moderate wave energy), so it’s small and a bit gutless. Still, with that offshore wind, it’ll be the cleanest you’ll see all week. It’s only surfable waves in very ordinary conditions, but it’s the best on offer.
The Thursday morning on the 13th sees a bump in size to 4 ft from the west, and the period stretches to 11 seconds, giving it a bit more grunt. The energy jumps to 328 (moderate to strong), but the wind is a cross-onshore from the NNW at 12 mph, which will chop it up and make it pretty messy. It’s a shame, as there’s some potential there, but the wind ruins it.
After that, it’s back to small, weak, and mostly wind-affected slop. The Friday the 21st sees a clean session with a cross-offshore ENE breeze at 16 mph and a 3 ft west swell, but the energy is low (111) and the period is a short 9 seconds. It’ll be clean but tiny.
Overall, don’t bother waxing up for a while. The 16-day forecast is a long, flat trudge with only a couple of brief, lacklustre windows. Keep an eye on the charts, but for now, it’s a waiting game.
