The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Honestly, it's a tough one for the reliable spots. The only break that popped up with any sort of recommendation is Harlyn, and even then, it's a spot that's inconsistent and for beginners only. The whole 16-day window is a bit of a struggle, with a lot of poor surf conditions and not much to get excited about. We're looking at a long stretch of nothing to write home about before we get to the end of the forecast.
The first real glimmer of something, and I mean a tiny glimmer, comes on Saturday, 5th September. Harlyn is looking at a 5ft swell from the WNW, with a long period of 11 seconds. That's a groundswell, and the energy is moderate (467). The morning has a light cross-shore with a slight air, so it could be surfable for a beginner on a longboard, but it's a marginal call. Water temp is a touch warmer than normal at 64°.
After that, it's back to the drawing board. Sunday the 6th has some offshore wind in the afternoon, but the swell is tiny – only 2ft – so there's just no power.
Then we get into a big, messy week. Monday the 7th sees a jump in the swell to 8ft from the W, with a very long period of 12 seconds and strong energy (1480), but it's choppy and cross-onshore. Not great. Tuesday the 8th is similar with a 8ft swell, but again, the wind is messy. This is a lot of water moving around, but it's all blown out.
The real standout, if you can call it that, is the very end of the run. On Tuesday, 15th September, we see a 4ft swell from the WNW with a very long period of 16 seconds for the morning. The energy is moderate (725), but the wind is a fresh cross-onshore which is a shame. The afternoon bumps up to 5ft from the WNW with a 15-second period, and energy is strong (1035). But again, the wind is onshore. That long period groundswell would be a dream at a point break or reef, but at a beginner beach break like Harlyn, it's likely to be too straight and hard to manage, especially with that onshore wind.
Then on Wednesday, 16th September, the morning looks a bit more promising. A 4ft swell from the WNW with a 13-second period, moderate energy (504), and a light cross-shore with a light breeze. That's probably the cleanest the water will look in the whole 16 days, but it's a far cry from a classic. It's a marginal call, but it's the best of a bad bunch.
So, if you're desperate for a splash on a big board, the morning of Saturday the 5th or the morning of Wednesday the 16th are your best bets. But don't expect any magic. For the rest of it, you're better off waiting for the next forecast update.
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.
