The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks. To be straight with you, it’s a tough stretch for Harlyn. This is a sheltered spot, and it shows. We’ve got a long, long gap of poor conditions before anything worth getting wet for shows up.
The best of the whole outlook is looking like Monday the 7th of September. It’s not perfect, but it’s our standout. The morning session is the one to aim for. We’ll have a 6ft swell rolling in from the west, and with a light offshore wind, it should be clean. The swell energy is moderate at 509, and it’s a proper groundswell with a 9-second period, so it’ll have a bit of push. Expect some decent, shapely waves. Harlyn can get crowded, so be prepared to share it.
Before that, we’ve got a whole heap of nothing. From now right through until the 7th, it’s mostly strong, messy winds and poor conditions. Winds are strong cross-off or cross-shore, and the swell is junky and short-period. There’s a bit of a pulse around the 8th of September, a Tuesday morning, with an 8ft west swell and a clean offshore wind, but it’s right on the edge of being too big for this spot and the energy is very strong (1264), so it’s more for the experienced crew.
The weekend of the 12th of September has a flicker of hope. Saturday morning, the 12th, we get a 8ft groundswell from the west-northwest with light, clean cross-offshore winds. The combined energy is strong at 1001, and it could be good. It’s a long way out though, so keep an eye on the charts.
Overall, it’s a lean run. If you’re desperate, Monday the 7th is your best bet. After that, the 8th for experts, and maybe keep an eye on that Saturday the 12th.

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.
