The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Poldhu Cove over the next couple of weeks.
Right off the bat, there’s a gap. The first few days of September are a write-off, with strong onshore winds and messy, poor surf conditions. You can forget about a paddle until at least Friday the 4th, and even then it’s only marginal.
The real action starts to build towards the second week. The standout window is looking like the morning of Thursday the 10th through to Friday the 11th. That Thursday morning, the wind goes clean, light cross-offshore from the north, and we’ve got a solid 10ft swell from the WSW. That’s a big, powerful swell with moderate wave energy (1026), and it’s going to be clean. This is for experienced surfers only – well over 8ft, so leave the beginner boards at home. Friday morning the 11th looks even better on paper: still a 10ft WSW swell, but with a lighter breeze and a very good surf rating. The energy is strong (1086), and the conditions are clean. That Friday morning is the pick of the entire forecast, no question.
The swell direction from the SW is close to the optimum for Poldhu Cove, but keep in mind that with a period around 8 seconds, it’s a shorter-period windswell, not a long groundswell. So the waves will be a bit steeper and more dumpy than a long-period groundswell. Still, with that offshore flow, it’ll be well-shaped.
After that, the wind gets messy again through the weekend and into the next week. There’s a pulse of bigger swell around the 16th, but the wind is howling from the NW, making it lumpy and poor for paddle surfing. That setup might be more interesting for the kite crowd.
The water temperature is sitting at 64°F with a 2° anomaly, which is about average for the time of year, so no need for a thick steamer just yet.
Overall, if you can get out on the morning of Friday the 11th, that’s your window. It’s a short window, but it’s a good one.
Rusty.

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.
