The Lowdown
Alright, let's talk Poldhu Cove. The next couple of weeks are a real mixed bag, with a lot of flat spells and only a few windows that might get you stoked.
The first real chance of a wave is on Thursday morning, 13th August. The swell picks up to a clean 4ft from the west with a solid 11-second period. The combined energy is moderate at 332, and with a light offshore breeze from the NNW, it'll be glassy. This is your best bet for a proper session, but the wind turns to a fresh cross-shore in the afternoon, so the morning is the time to be in the water.
After that, it drops back into the doldrums. The swell fades and the wind gets messy. The 19th of August sees a slight return of some 4ft WNW swell, but it's average. Not worth rushing for.
The standout window is actually Thursday, 20th August. The swell is consistent at 4ft from the west, with a 10-second period and a combined energy of 266. The wind goes offshore from the NE and NNE, getting light in the afternoon. It's clean, surfable, and the best quality on offer. It's not a big swell, but it's the most reliable we've seen.
The following days, 22nd and 23rd, have some half-decent surfable conditions, with the 23rd morning seeing a glassy, 3ft west swell. It's a nice, small-wave option for a quiet Sunday session.
The long-range stuff into the 24th looks like it'll fade again, nothing to get excited about.
Overall, this is a classic late-summer slow period. The Thursday the 20th is the one to circle. It's not a beast, but it's the best we've got and it'll be clean. The rest is mostly a write-off, but the forecasts can change.
