The Lowdown
Alright folks, it’s Rusty here, and I’ve got to be straight with you – the outlook for Harlyn over the next 16 days is a tough one. We’ve got a real blank stretch ahead, with nothing surfable on the cards until well into the second week. The whole period is plagued by poor conditions, mostly due to wind and swell direction issues for this sheltered spot.
Looking at the guidance, Harlyn is a beginner-friendly, inconsistent break that really only works with a clean WNW swell and offshore winds. That setup just isn't showing up for the vast majority of this run. There’s a long gap with no worthwhile surf at all from now until about September 7th.
The first hint of something rideable shows up on Monday, September 7th. The morning sees a clean 5ft swell from the west with a very long period of 12 seconds. The water is a touch warmer than normal at 66°. This is a proper groundswell with moderate wave energy (692). That long period could make for some nice lines at this kind of sheltered spot, though it might break a bit straight if you're surfing a beach break. The offshore wind from the southwest will have it looking clean. Monday afternoon holds similar potential with 6ft of west swell and an 11-second period, still clean with a cross-off breeze. This is the best we've got, but with Harlyn being inconsistent, don't expect perfection.
Tuesday, September 8th looks like a write-off again as the wind swings onshore, pushing messy 5ft and 5ft swell into the beach. The rest of the forecast after that drops off significantly, with tiny, onshore-affected surf right through to the end of the period on September 14th. There’s a moment on Saturday the 12th with a 3ft, 11-second west swell, but it’s onshore wind again.
Honestly, the only standout window is that Monday, September 7th. It’s not going to be epic, but it’s the cleanest, most substantial swell we’re going to see in this entire run. The rest is a bit of a drought. Keep an eye on the forecasts, but for now, don't get your hopes up too high.
Stay salty,
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.
