The Lowdown
Alright, let's gather round the water and look at what the charts are telling us for the coming days here. Honestly, it's looking like a waiting game. The next couple of weeks are mostly on the small and bumpy side, but there are a couple of windows that could offer a proper reward if you're patient.
The pick of the bunch, no doubt, is Poldhu Cove. Everything's pointing towards the morning of the 13th of August as the best slot in the short range. We've got a clean, 4-foot swell rolling in from the WSW, a proper 11-second period, so there's some push behind it. The wind is a light cross-off from the NW, 9 mph, which should leave it looking tidy. The water's a touch warmer than normal at 67°, so that’s a bonus. The combined energy is solid (343), meaning there’s a good amount of juice in the water. It’s a standout morning.
But keep in mind, Poldhu Cove can be inconsistent, so you might have to sit and wait for the sets. And because it's a good option, don't be surprised if there are a few others out there with the same idea, as crowds do show up sometimes.
After that Thursday morning high, it goes pretty quiet. We’ve got a long, boring stretch from the 14th right through to the morning of the 27th of August. A lot of small, weak swells and onshore to cross-shore winds. The 18th of August sees a slight bump in size with 5-foot swell, but it's sloppy, short-period stuff at 6 seconds and blown out by strong cross-onshore wind. Not worth paddling out for. The 23rd of August actually throws up some bigger numbers, like a 8-foot swell, but it's a messy south wind and a short period, so it's just a lumpy, choppy mess.
The 27th of August is where it starts to get interesting again. The afternoon session looks promising with 6 feet of WSW swell, moderate offshore wind from the NE at 12 mph, and the energy jumping up to 344. That's a clean-looking window after a long dry spell. The 28th of August morning looks even bigger, at 6 feet with a fresh offshore, but with that size and an 8-second period at a beach break, it might be a bit fast and dumpy for the average punter. That one's for the experienced crew only.
So, to sum it up: the best bet is Thursday morning the 13th of August for a classic, clean session. After that, you’re twiddling your thumbs until the 27th and 28th, where the potential is there but the quality is still a question mark this far out. Good things come to those who wait, I suppose.
