The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer down at Poldhu Cove over the next couple of weeks.
It’s a pretty quiet start, I’m not gonna lie. For the first week, we’ve got barely a ripple. The water is a balmy 66° – that’s about 4.5° warmer than usual for this time of year, so it’s a proper warm bath, but there’s no push to it. The combined energy is stuck in the doldrums, peaking at a measly 33 (33) on the Wednesday morning. It’s just not enough to get excited about. You’d be bobbing around on a longboard if you’re desperate, but it’s a paddling holiday, not a surf one.
The wait is a long one. We finally see a real pulse of swell arriving on Saturday, July 26th. The morning brings a 6.2ft west swell with a short 8-second period, and the combined energy jumps to 426 (426). That’s got some grunt, but listen – the wind is a strong cross-onshore from the west at 18 mph. It’s going to be lumpy, choppy, and messy. That size is already pushing into expert-only territory, and with that wind, it’s a washout for the paddle. Honestly, if you’ve got a kite, this Saturday and Sunday look more interesting than a surfboard.
The pattern doesn’t clean up much after that. There’s a glimmer on Wednesday, July 30th, with a 6.2ft swell from the WNW, but the wind is onshore at 18 mph – that’s a no-go.
Finally, there’s a flicker of hope on Friday, August 1st. The morning sees a 4.6ft WNW swell with a 7-second period, but the wind swings offshore from the northeast at 18 mph. The combined energy is still 284 (284) – moderate to strong – and the offshore breeze should clean it up. It’s a week and a half away, so don’t bank on it, but that’s the only window where Poldhu Cove might offer a few short, punchy waves for the more experienced crew. The afternoon drops off a bit, and the crowds are likely to be there if it turns on.
Best Bet: The only real standout in this whole 16-day window is Friday, August 1st, morning. It’s not perfect, but it’s the closest we get to clean, offshore conditions with a bit of size. Keep your fingers crossed.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Poldhu Cove may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
