The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Poldhu Cove. It’s a bit of a slow start, but there’s a real glimmer of something special if you’re patient.

The immediate picture is pretty grim for the next week or so. We’re looking at a stretch from Monday the 7th right through to the 14th of September where the conditions are just not cooperating. The wind is mostly cross or onshore, and the swell is messy. There’s a window on Tuesday morning the 8th where the waves are a manageable 5 ft from the West, but the wind is a stiff 22 mph from the NNW. It’s clean, but that’s a lot of breeze for a proper paddle. We’re looking at moderate combined energy (539) which is not enough to get excited about. The rest of that week is a write-off, with poor surf conditions and small, choppy swell. There’s a decent-sized 7 ft from the WSW on Monday morning the 7th with a strong 13-second period showing a massive 1574 combined energy, but the 12 mph WNW crosswind makes it a lumpy mess. It’s a no-go.

Now, keep your eyes on the second week. The real story starts to shape up around Tuesday the 15th of September. The morning brings a clean 5 ft swell from the West with a moderate 10-second period, combined energy of 558, and a light 9 mph cross-offshore from the North. That’s the turning point. The water is a touch warmer than normal at 64°F, which is a nice bonus for this time of year.

But the absolute standout, the one you want to circle on the calendar, is Wednesday the 16th of September. The morning is looking fantastic: a clean 5 ft from the West with a pumping 11-second period, light offshore wind from the NNE at 6 mph, and good energy (461). The afternoon is even better. It goes completely glassy – calm wind, 0 mph from the ENE. The waves will be a silky 4 ft from the West with a 11-second period and 321 combined energy. That’s a dream session for Poldhu. It’s got that long-period groundswell energy, which is perfect for this fairly exposed cove. Keep in mind, this spot is inconsistent, so when it comes together like this, you don’t want to miss it. Thursday the 17th and Friday the 18th still have some size, 5 ft to 6 ft from the West, but the wind picks up to a strong 22-25 mph from the East, which will be clean but a battle.

The last big shout is Sunday the 20th of September. The afternoon session is looking very good. We’re talking a solid 6 ft from the West, 11-second period, with a gentle 9 mph cross-offshore breeze from the ESE. Combined energy is a healthy 793. That’s proper waves for a decent paddle, and the wind will have it looking clean. The morning is a touch bigger at 7 ft, but with stronger wind, so the afternoon is the pick.

The gap between the first decent surf and the real magic is about a week. Hang in there, because the 16th and 20th of September are the ones to get out of work for.

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.
