The Lowdown
Right then, grab a coffee. Rusty here, with the look ahead for Harlyn.
To be straight up with you, this 16-day window is a tough one. We’ve got a big gap of quiet water to start, and most of the time when there is swell, the wind is just too mean to make it worth your while. There’s one date that stands out, but it’s a way off, so don’t hold your breath just yet.
The first few days aren’t happening. Monday the 31st of August and Tuesday the 1st of September see the swell either way too blown out or too weak to be any fun. You’ll be staring at a messy, choppy ocean with no real option.
Wednesday the 2nd through to Saturday the 6th of September are a write-off as well. The wind is either too strong or from the wrong angle for Harlyn, and the waves are just poor quality. Expect a blank run that stretches nearly a week.
Now, things get a little more interesting on Sunday the 7th of September. The morning has tiny, 2ft swell with a very long period of 14 seconds, and it is clean. The wave energy is weak (292). It’s a groundswell, but it’s so small it’s just a fun-sized novelty for beginners on a longboard.
Tuesday the 8th of September is the one to circle on your calendar. This is the standout. The morning sees a nice 7ft swell from the west, with a gentle breeze making it clean. The combined energy is moderate (718), and it shapes up for the best surf of the whole outlook. It’s a bit on the bigger side for beginners, but for the rest of you, this is the session to aim for.
After that, the wind turns ugly again from Wednesday the 9th right through to Sunday the 14th of September. Fresh onshore and cross-shore winds kill everything, and the swell drops away to nothing. Another long gap of poor conditions.
Finally, on Monday the 15th of September, we see a flicker of hope. The morning brings 3ft swell with an 11-second period from the west, but it’s still very weak (224) and only just surfable. Nothing to get excited about.
So, there you have it. One solid chance on Tuesday the 8th of September morning. Don’t blink, or you’ll miss the whole summer. Forecasts can change, but right now, it’s looking lean.
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.
