The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Poldhu Cove. Honestly, the first week is a bit of a struggle. The swell is tiny and the wind is all over the shop, so we’re not looking at much action until we get deeper into the forecast.
The real standout in this whole 16-day window is Thursday, 20 August. The morning is a write-off, but by the afternoon, things start to click. The swell jumps to a solid 8ft from the WNW, and that’s packing some serious grunt with a combined energy of 1917 – that’s very strong wave energy. The kicker is the wind turning cross-offshore from the NNW at 12 mph, keeping the surface clean. At that size, this is strictly for experienced surfers only; it’s well over the 8ft mark in the morning, but the afternoon is still big. Keep an eye on the tide, though, as the report flags it as a bit marginal.
Following that, Friday, 21 August morning is a solid secondary option. The swell drops to a more manageable 5ft from the WNW, with a period of 10 seconds, and a clean cross-offshore breeze from the ENE at 6 mph. The combined energy is still a healthy 420, so there’s plenty of push. The water temp is sitting at 66°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.
The rest of the first week is a write-off. From Saturday 9th right through to Wednesday 13th, the swell is mostly 1ft to 3ft, and the wind is often cross or onshore, making for poor conditions. You’ll be scratching your head. There’s a slight bump on Thursday 14th and Friday 15th with 4ft to 5ft swell, but the wind is still messy, so it’s nothing to get excited about.
Heading into the second week, the swell tries to build again around Tuesday 19th, but it’s a lumpy 7ft with cross-winds, so it’s not really clean. The focus is definitely on the 20th and 21st. After that, the swell fades back down to 2ft to 2ft through the weekend of the 22nd and 23rd, with clean offshore winds, but it’s just knee-high.
So, to sum it up: the best of the best is Thursday afternoon, 20 August and Friday morning, 21 August at Poldhu Cove. It’s a long wait, but it could be worth it. Keep your fingers crossed the forecasts hold.
Rusty.
