The Lowdown
Right, grab a seat. It’s Rusty here, and I’ve gotta be straight with you – the next couple of weeks at Harlyn are looking pretty grim. We’ve got a long, quiet stretch ahead, so don’t get too excited just yet.
The first real chance of anything surfable doesn’t pop up until Monday the 14th of September, and even then, it’s barely a whisper. Early that morning, we’re looking at a tiny 0.6m (about 2ft) swell from the west, with a period of 9 seconds. The combined energy is weak, just 85 (weak energy), and while the breeze is light and clean, the wave comment is “surfable waves but very ordinary conditions.” That’s about as generous as I can get.
Before that, it’s a complete blank. From now until that Monday, there’s nothing worth paddling out for. The wind is mostly onshore or cross-off, and any swell that shows up is accompanied by poor surf conditions. You’d be better off checking the wind forecast for a kite session, because the waves here aren’t going to give you much joy.
The best of a bad bunch actually comes a couple of days later, on Wednesday the 16th of September. The morning session looks glassy – wind is almost nothing, from the south, and the water is flat calm. But don’t be fooled; the swell is still only 0.5m (about 2ft) from the west, with a period of 10 seconds and energy at 82 (weak energy). It’s surfable, but only just.
The afternoon of the 16th has a bit more size, with a 1.1m (about 4ft) west swell, but the period jumps to 12 seconds and the energy hits 400 (moderate wave energy). The catch? The wind is onshore and the forecast is “marginal.” For a sheltered spot like this, that long-period groundswell might not wrap in cleanly – it’s more of a point break or reef kind of wave.
Overall, Harlyn is inconsistent at the best of times, and this run looks like one of those stretches where you just wait for the next system. Never stays poor forever, but right now? It’s a struggle.
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.
