The Lowdown

Right, let’s get real about Harlyn for the next couple weeks. The finder’s not giving us much to work with—pretty much a flat spell with a few flickers that just don’t line up.

First up, the overall picture: We’re looking at a pretty grim run. There’s not a single standout session here. The water temps are running about 66°F with a 4°F anomaly, so that’s a touch warmer than normal for this time of year around here, but it’s small comfort when the surf is this lacklustre.

Friday 28 August kicks off with tiny 1 ft swell from the WNW, a 19-22 mph cross-off wind, and the combined energy is weak at 21. It’s rain showers and poor conditions—honestly, not worth paddling out.

Saturday 29 August sees a bump of energy. Morning has 5 ft SW swell with a clean offshore S wind at 22 mph and moderate energy (182). The afternoon jumps to 8 ft WSW swell, period dropping to 7 seconds, and strong to very strong energy (1039), but the wind swings to a messy 28 mph cross-shore—only for experts, and even then the conditions are poor.

Sunday 30 August morning offers the closest to a maybe: 5 ft W swell, 9-second period, SSW offshore at 16 mph, and moderate energy (348). They call it “surfable but very ordinary.” Not great, not terrible, but far from a standout. The afternoon goes downhill with rain and cross-off wind.

Monday 31 August pushes 8 ft in the morning, but it’s cross-on wind, lumpy, and just poor. The energy is very strong (1085), but the quality isn’t there for paddle surfing.

Tuesday 1 September through Sunday 6 September is a long stretch of weak to moderate energy, tiny waves, and mostly poor conditions. The best of a bad bunch is Thursday 3 September morning: 6 ft W swell, 8-second period, cross-off SW wind at 16 mph, moderate energy (358), clean conditions—but it’s still only a 1 out of 10 in the guidance, so no real recommendation.

Monday 7 September has 7 ft W swell in the morning with gentle cross-shore wind (9 mph), moderate energy (402), but it’s marginal. The afternoon improves slightly to 6 ft with light cross-off and clean conditions (350), still just “surfable but ordinary.”

After that, from Tuesday 8 September onwards, the swell drops away hard, with energy values in the double digits and small period windswell from the NW. By Thursday 10 September, we’re down to 2 ft and 5-second periods—barely a ripple.

The bottom line: There’s no session in this 16-day window that I’d genuinely recommend. If you’re desperate, maybe sneak out Thursday 3 September morning or Monday 7 September afternoon for some clean 6 ft waves, but don’t expect anything special. Given Harlyn is a sheltered, inconsistent spot, this kind of blank run isn’t unusual. Forecasts can change, but right now, I’d leave the board at home and maybe look up at the wind—if it strengthens, this setup might be more interesting for kite surfing than paddle surfing.

Stay patient.

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.
