The Lowdown
Alright folks, Rusty here with a look at what's on the menu for Poldhu Cove over the next couple of weeks. Gotta be straight with you – it's a bit of a mixed bag, and the first few days are pretty grim. We've got a long stretch of poor surf conditions to sit through before we see anything worth paddling out for.
So, the outlook starts slow. Real slow. For the first week and a half, from Sunday the 6th through to about Thursday the 17th, it's mostly a write-off. The winds are all over the place – mostly cross, cross-on, or straight onshore – and that's just chopping everything up. There are some solid pulses of swell in there, with the combined energy hitting some impressive numbers like 1571 on Monday the 7th and 1201 on Tuesday the 8th, but the wind ruins it. It's a real shame, 'cause there's some proper juice in the water, but it's all messy and lumpy. The water temp is sitting around 64°F, which is a touch warmer than normal for this time of year, so at least you won't freeze while you're getting disappointed.
Now, after that long, bleak stretch, we finally get a glimmer of hope. Saturday the 19th of September is the standout window. The morning shows a clean 5ft swell from the west with a moderate offshore breeze from the northeast, and the combined energy is a solid 541. That's the kind of wind that will put a smile on your face – clean, smooth faces. The afternoon gets even better: a light cross-off breeze from the east-southeast, a 5ft west swell, and a combined energy of 502. The water's still that same warmer-than-average temp. This is the day to circle on your calendar. The waves will have that longer-period (11 seconds) groundswell feel – more energy, better shape, but longer waits between sets. It might be a bit too much for beginners at 5ft, but for the rest of us, it's on.
Sunday the 20th also has potential, with a bigger 7ft to 7ft west swell and a clean cross-off wind, but the combined energy jumps to over 1000, which means it's powerful. The wind is a bit stronger, too, so it could be a bit more challenging. That's more of an expert wave at that size, especially with the long period (11 seconds) – it'll be fast and hollow.
So, to sum it up: there's a big gap of nothing for over a week, but if you can wait, the weekend of the 19th and 20th offers the best chance of some proper, clean waves at Poldhu Cove. Don't expect a lot of consistency, but when it's good, it'll be worth the wait.
Stay patient, keep an eye on the horizon.

Information about the Poldhu Cove Surf forecast
The above surf forecast table for Poldhu Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Poldhu Cove can be found by selecting the local surf guide option on the grey menu. Our Poldhu Cove surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Poldhu Cove) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
