The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Harlyn over the next couple of weeks. I gotta be straight with you – it’s a tough stretch. The finder’s only flagged one day with a score worth a mention, and even that’s a bit of a maybe. Let’s break it down.
We start off with a real quiet spell. From Wednesday the 26th of August right through to Saturday the 29th, it’s pretty much a write-off. Small, weak swell, poor conditions, and the wind is just messing with it. The water is sitting at 66°, which is a touch warmer than normal for this time of year, but that’s about the only nice thing I can say for those first few days.
Sunday the 30th of August morning is the only real standout in the whole 16-day window. We’ve got a moderate offshore wind from the SSW at 16 mph, which should keep things clean. The swell is 6 ft from the West, with a period of 9 seconds. Combined wave energy is moderate at 484. It’s not a classic groundswell, but on a sheltered spot like Harlyn, that clean offshore and a bit of size could make for a fun session. It’s a beginner break, so that 6 ft is getting near the top end for less experienced folks, but for a confident surfer, it’s worth a look. Just be aware that crowds are often here.
After that Sunday morning window, it turns ugly again. Monday the 31st brings a big pulse of 10 ft swell from the West, but the wind is a fresh cross-onshore and the energy is strong (1484). That’s not a paddle set-up; that’s a kite-surfing day if anything. The rest of the first week of September is a mix of lumpy cross-shore winds and small, weak swell. There’s a brief moment on Wednesday the 2nd of September morning with a tiny 3 ft swell and light winds, but it’s just too small to get excited about.
We get into the second week, and it’s still a grind. The swell sticks around the 5 ft to 7 ft mark, but the wind is almost always wrong – cross-shore or cross-onshore. The few moments with offshore wind, like the 6th of September morning, are let down by marginal surf conditions or questionable tide. The combined energy on that Sunday the 6th hits 518, which is solid, but the overall quality isn’t there.
The 7th of September Monday afternoon has a clean offshore wind and 4 ft swell, but it’s ordinary at best. The 10th of September morning has a clean cross-offshore wind but a short-period 5 ft north swell, which just doesn’t work well for Harlyn’s sheltered westerly exposure.
So, if you’re looking for the best of a bad bunch, your one and only real highlight is Sunday the 30th of August morning. The swell is a decent 6 ft from the West, with that clean offshore wind. It’s not huge, but it’s the only time the forecast lines up for a clean paddle. Don’t expect much else in this 16-day window, mate. It’s a flat spell with a couple of wind-swell bumps that just don’t deliver.
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.
