The Lowdown
Alright, grab a coffee, let’s have a look at what’s cookin’ for Harlyn. This little spot is tucked away, sheltered, so it never really sees the big ocean energy. That means we’ve got a long, quiet stretch ahead. For the first few days, there’s just not enough to get excited about, and that dry spell runs right through until Monday the 7th.
Monday 7th September is when we finally see some life. The swell bumps up to 7.5 ft out of the west-northwest with a period of 13 seconds — that’s a proper groundswell. Combined energy is a solid 1783, so there’s real push behind it. Now, that size is gonna be well overhead here, maybe a touch too much for the beginners, but for the lads who know what they’re doing? Could be a fun one. Wind’s cross-shore though, a moderate breeze, so it’ll be a bit rippled, not glassy. The direction (WNW) is right on the money for Harlyn, so the setup should work. It keeps going into the afternoon with 7.2 ft and a cleaner cross-off wind, which is a nice little window. Still, it’s Harlyn – crowds are often here, so don’t expect it to yourself.
After that surge, it gets messy. Tuesday 8th has 6.9 ft but a strong, fresh cross-shore wind and rain showers, turning it into lumpy chop. Not worth the paddle.
We get another small chance around Thursday 10th September in the afternoon. Swell drops to 6.2 ft from the west, period a short 8 seconds, but the wind goes cross-off with a gentle breeze, so it turns clean. Combined energy is 466 — moderate at best. It’s rideable, but nothing special. Probably a session for the longboard or a fun mid-length.
Beyond that, it’s a real struggle. From the 11th right through to the end of the 16-day window, the swell just fades away and the winds are either onshore, howling offshore (which can be a nightmare to paddle into), or just too light. There’s a moment on Saturday 19th September in the afternoon where it goes dead glassy, but the swell is a tiny 1.3 ft — you’d be floating. That’s not surf, that’s a swim.
So, if you’re keen, Monday 7th September is your best bet. It’s the only time the energy really lights up. After that, it’s a long, slow slide into flatness. Hang in there, mate. Forecasts can change, but right now, it’s a tough one.

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.
