The Lowdown

Alright mate, Rusty here. Let’s break it down for Harlyn.

I won’t sugarcoat it—this stretch is a lean one. The first week is basically a no-go: onshore winds, lumpy cross-chop, and messy conditions. The only time you might get wet is the morning of Thursday 10 September. It’s small, around 4ft from the west, short period, and just ordinary. The wind is offshore, so the surface will be clean, but the energy is weak (134) and it’s barely surfable. The next few days stay small, mostly under 4ft, with short period and hardly any punch. There’s no real standout.

Into the second week, it doesn’t get much better. Monday 14 September afternoon shows a jump in period to 12 seconds with 4ft swell, but it’s marginal. Wednesday 16 September is a washout with strong onshore wind and messy conditions. The one session that stands out is the afternoon of Thursday 17 September—around 8ft from the west, 11-second period, clean with cross-off wind, and moderate energy (1304). That’s the biggest, cleanest swell of the whole outlook. For Harlyn, with that size and cross-off wind, it might still be tricky with the tide, but if you’re keen, that’s your best chance.

The water temperature is about 65°, which is a touch warmer than usual for this time of year—about a degree and a half above average. Nothing wild.

So, first week is mostly a gap of poor surf with only a couple of ordinary, small windows. The second week gives you one possible session on the 17th, but it’s not a sure thing. If you’re waiting for clean waves, you’re in for a long wait. But forecasts can change.

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.
