The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for Harlyn is a tough one to write. We’ve got a full 16-day window ahead, but honestly, looking at what’s on the cards, it’s a real struggle to find a proper session. The forecast is pretty much a desert of poor surf conditions, and the only real glimmer of hope comes right at the very end.
The first solid recommendation doesn’t roll in until the morning of Sunday, 30 August. And even then, it’s not a classic. The water temperature is about average for the time of year, so no surprises there. The swell is coming in at 6 ft from the W, with a combined energy of 473 (moderate). The wind is a moderate offshore from the SSW at 12 mph, which will keep things clean. The period is 9 seconds, so it’s a decent groundswell. But here’s the kicker – Harlyn is a sheltered spot, inconsistent, and it’s rarely breaking. The crowds are often there, so you’ll likely have company. The morning of the 30th is your only real chance, and it’s a 2/10 on the quality scale, so keep expectations low.
After that, it’s a long, bleak run. We’ve got a gap from Sunday afternoon all the way through to Sunday, 6 September before we see another mention of surfable waves. That’s a full week of marginal or poor conditions. On the morning of Sunday, 6 September, the swell is 5 ft from the W with a combined energy of 371 (moderate) and a 9-second period. The wind is a gentle cross-offshore from the WSW at 9 mph, which keeps it clean. But the guidance says “surfable waves but very ordinary conditions,” and it scores a 1/10. It’s not something to get excited about.
Then we have a couple of marginal calls on Monday, 7 September – the morning sees 8 ft from the WNW with a 8-second period and combined energy of 695 (moderate), but the wind is a light cross-onshore from the NW at 3 mph, creating ripples. The afternoon is similar. After that, the rest of the outlook is a mix of onshore winds and tiny or messy swell, with nothing worth paddling out for.
So, to sum it up: the best of a bad bunch is the Sunday, 30 August morning with that 6 ft W swell and clean offshore wind. Everything else is a washout. If you’re desperate, you could check the 6 September morning, but don’t expect much. For a place that’s this inconsistent, a blank run like this is more normal than you’d hope.
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.
