The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks, but brace yourselves – it’s a pretty grim start.
Right now, and for the best part of the next week, we’re looking at a real drought. The first week and a half is basically a write-off. There’s wave energy, sure, but it’s all wrapped up in dodgy winds and messy conditions. We’re talking about a long stretch of poor surf with nothing worth paddling out for until at least the 15th. That’s a solid 8 days of rubbish.
The first proper glimmer of light comes on Tuesday morning, the 15th of September at Harlyn. This is the one to circle. We’ve got a clean 6ft swell rolling in from the WNW, with a decent 12-second period. The wind is almost non-existent, a slight offshore breeze from the WSW, which should leave the surface super clean. The combined wave energy is moderate (872), and for a spot that’s usually sheltered and inconsistent, this is a real treat. The wave direction is a good match for the break’s favoured WNW direction. It’s a beginner-friendly break, but with this quality and clean conditions, any surfer on a log or a mid-length will be grinning. Downside? It’s a quiet spot, but with a window like this, expect a few locals to show up – crowds are possible.
After that, the window closes again pretty quick. The following days bring a mix of big, messy energy and strong winds. That Thursday morning, the 17th, sees a massive 13ft swell from the WNW with a solid 11-second period and very strong energy (4046), but it’s accompanied by a fresh breeze and lumpy cross-shore chop. That’s purely for the experts, and even then, it’s going to be a battle. Honestly, for a sheltered spot like Harlyn, that’s more of a spectacle than a session.
So, to sum it up: the first 8 days are a total loss. The standout is undeniably Tuesday morning, the 15th at Harlyn. After that, things get big and messy. Keep your eyes on the sky, but for now, the 15th is your only real shot at a classic, clean wave.
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.
