The Lowdown
Alright, Rusty here. Let's have a look at what’s cookin’ for the Harlyn stretch.
Honestly, this forecast is a tough one to read. The next 16 days are looking bleak for us. We've got a real dry spell on our hands, so don’t get your hopes up for much more than a few grovel sessions.
Things start off with a pulse of energy on Monday, September 7th. We’re talkin’ a solid 7ft swell from the west, with a decent 13-second period—that’s got some proper weight behind it. In fact, the combined energy is massive at 1632. Sounds good, right? Well, the wind is howling out of the WNW at 16 mph, a messy cross-shore, so it’s gonna be a choppy, blown-out mess at this sheltered spot. It’s really just a marginal situation.
By Monday afternoon the wind switches to a cleaner cross-off, but you’re still looking at a drop in size and that same ugly lump from the morning. It's a write-off for a decent wave.
Tuesday the 8th is worse. Stronger onshore winds and a drop in period make for poor, lumpy conditions. We then hit a real flat spot from Wednesday the 9th right through to the second weekend of September. The swell drops away to nothing—we’re talkin’ knee-high dribble with negligible energy (down to 44). There’s a little bump on the 11th with 5ft, but the quality is “very ordinary,” which is code for frustrating.
The water temp is sitting at 65°F, which is a touch warmer than normal for this time of year (anomaly of 3°F). So at least the grovel won't be cold.
After the 11th, it’s just a long, sad procession of small, weak, or wind-affected junk. You get days where the wind lays off, like the 12th and 14th with clean conditions, but the swell is barely a ripple. The 15th shows a spike to 6ft with a longer 11-second period, but that’s matched with a fresh 22 mph cross-shore wind, making it a lumpy, blown-out mess—more of a kite-surfing kind of day than a paddle session.
The final week is a ghost town. Swell heights barely crack 3ft, and the energy figures are stuck in the double digits. It's a flat, windblown end to the outlook. There is simply no standout session in this window. Nothing to get excited about.
Keep your stick waxed, mate. This blank run is pretty normal for this area, and forecasts can always change. But as it stands, stay home.
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.
