The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks. Right now, it’s a real quiet start, so don’t be in a rush to grab your board. We’ve got a long stretch of nothing much on the cards.

Poldhu Cove is a fairly exposed spot that picks up a SW swell best, but it’s been inconsistent lately. The water is sitting at 66°F, which is a touch warmer than what you’d expect for this time of year—nothing wild, but a pleasant little anomaly if you’re paddling out.

The first few days are a write-off. From Friday the 21st right through until the end of the month, it’s one poor surf condition after another. The swell is tiny, with heights barely scraping 2 ft on the better days, and the wind is often a cross-off or cross-on breeze that just doesn’t allow the waves to clean up. There’s a brief flicker of energy on the 26th with a 5 ft to 6 ft SSW swell, but the wind is cross-on and messy, making it a total washout. Honestly, the whole first week is a dud for surfing.

We hit a bit of a gap here, but around the 1st of September, things start to wake up. The morning of the 1st sees a solid 7 ft swell from the west, with a combined energy value of 1132, which is a proper chunk of power. But the wind is a light cross-on, so it’s going to be a bit lumpy. It’s only a marginal call, and the afternoon drops off. Not a standout.

The real window you want to watch is the Thursday morning of the 3rd of September. The swell is 5 ft from the west, with a period of 6 seconds, so it’s a short-period wind swell. The wind is light—just 3 mph from the WNW, making it a cross-shore with only small ripples. That’s close to glassy, and it’ll be clean. The combined energy is a moderate 339, so there’s enough push to get a few fun ones. This is the best on offer in the whole outlook. It’s not a monster, but for a clean, surfable wave with no crowds to worry about (it’s only “sometimes” busy), this is your moment.

After that, the 5th of September also looks promising. The Saturday afternoon has a 3 ft west swell with glassy conditions—wind is dead calm. It’s small, but if you’re after a longboard session in clean water, that’s a beautiful call. The energy is low at 122, so it’s weak, but the glassy surface makes it worth a paddle.

Overall, don’t get excited for the first week. The best surf comes on the 3rd and 5th of September. Keep your eyes on the horizon for those cleaner days.

Rusty.

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.
