The Lowdown
Alright folks, Rusty here. Let's break down the 16-day picture for Harlyn. It’s a tough stretch, so don’t get your hopes up too high.
We start on Wednesday, the 2nd. The water is a touch warmer than average for this time of year, about 65°. The swell is there, but it’s junk. The wind is a cross-off, keeping things clean, but the wave quality is poor. The combined energy sits at 174 (moderate), but the 5ft to 6ft swell from the west-southwest is short-period, not holding any shape. Thursday and Friday are more of the same—wind is moderate to fresh, and the swell is still junky. Friday sees a bigger pulse of 7ft with cross-on wind, which is just a choppy mess.
Now, Saturday the 5th is the one bright spot in the near term. The swell drops to 4ft, but the wind goes glassy—we’re talking a slight air from the southeast. For a sheltered spot like Harlyn, that’s gold. The swell is from the west with a longer 11-second period and a combined energy of 388 (moderate). It’s a point break setup, so that long period will wrap in nicely. The waves are just surfable, nothing epic, but with the glassy conditions, it’ll be clean. Keep in mind the crowds are often here, so don’t expect a secret session.
From Sunday the 6th, the swell collapses. We’re down to 2ft for the morning and 2ft in the afternoon, with the combined energy dropping to 64 and 43 (weak). It’s flat and small for a few days. The wind shifts offshore on Sunday afternoon, which is a tease, but there’s nothing to ride.
Monday the 7th brings a big spike: 7ft to 8ft swell from the west, with a 12-second period. The combined energy is massive—1321 and 1423 (strong to very strong). This is a solid winter groundswell. But the wind is a fresh to strong cross-off, which keeps it clean, but the wave comment says marginal or poor. That’s a lot of juice for a sheltered spot, and it might be breaking too straight for the beach. It’s also in the 8ft range, so this is for experts only. The rest of that week and into the next is a mix of onshore wind, messy chop, and small swell. The energy drops back to weak numbers (53, 30) by the 10th.
The second week is a dead zone. From the 12th to the 17th, the swell is tiny—2ft to 4ft—with weak combined energy often under 100. The wind is a mix of cross-off and cross-shore, keeping it clean but offering nothing to ride. The 14th of September sees a 5ft, 11-second swell with moderate energy (526), but the wind is off, so it’s clean. The wave comment is still marginal, which means it’s probably not worth the paddle.
Overall, the only standout is Saturday the 5th: glassy, clean, and a little pulse from the west. The rest is a write-off. For a spot like Harlyn, this is a pretty normal blank run. Forecasts can change, but right now, set your alarm for Saturday morning.
Rusty.

Information about the Harlyn Surf forecast
The above surf forecast table for Harlyn provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Harlyn can be found by selecting the local surf guide option on the grey menu. Our Harlyn 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 (Harlyn) 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 Harlyn 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.
Harlyn is 6 km (4 miles) from Padstow. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Padstow. Padstow has rooms for a wide range of budgets as well as car hire and transport links.
