The Lowdown
Alright folks, Rusty here. Let’s have a look at what Poldhu Cove has in store for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch ahead. The whole 16-day window is pretty much a write-off for decent waves. We’ve got a long gap of poor conditions starting now and running all the way through to the end of the period. There isn’t a single standout session worth paddling out for.
The water at Poldhu Cove is sitting at 66°F, which is much warmer than usual for this time of year, so that’s a little bonus if you do fancy a swim, but for surfing? Not much to get excited about.
Wednesday the 5th kicks things off with a 7ft west swell, but with a short 7-second period and a stiff 19 mph cross-wind, it’s just lumpy, poor quality stuff. That combined energy reading of 436 (moderate) doesn’t mean much when the wind’s ruining it. Through Thursday and Friday the swell drops right off to under 3ft, and while Friday morning goes glassy with 1.0ft, it’s just too small to ride. The weekend sees a bit of cleanish conditions with light ESE winds on Saturday, but we’re still stuck with knee-high dribble.
Things try to pick up again around Wednesday the 12th with a 3ft west-southwest swell and a 9-second period, but the wind is onshore and messy. By Thursday the 13th we’ve got 6ft swell, but it’s accompanied by 19 mph cross-winds and a lumpy chop – not worth the drive. The biggest pulse comes in on Sunday the 16th of August with a 7ft to 8ft west swell, combined energy hitting 561 to 675 (strong), but again the period is short and the wind is cross or cross-on. That’s expert-only territory with the size, and the quality just isn’t there.
Honestly, for this stretch, the setup looks more interesting for kite surfing than paddle surfing, especially when the wind gets up. There’s no real window of clean, rideable waves for us surfers. Hang in there, forecasts can change, but for now, keep the board in the car and don’t hold your breath.
Rusty.
