The Lowdown

Alright, let's get into it. I'm not gonna sugarcoat it – this is a grim stretch for Harlyn. The whole 16-day window is a write-off for any kind of worthwhile surf. You're looking at a solid gap of over two weeks with nothing that gets the heart pumping.

We kick off on Wednesday the 5th of August. There's some swell around, but the wind is a mess. It's a fresh cross-shore all morning, making for a lumpy, choppy surface. The afternoon is a little better with a moderate breeze, but it's still cross-onshore and choppy. The water is a touch warmer than average for this time of year, sitting at 65°F, but that's the only small mercy. The swell energy is moderate (388) but it's coming from the west with a short 7-second period, creating messy, weak waves. Not worth paddling out.

Thursday the 6th doesn't get any better. The swell drops right off, and the wind stays cross-onshore. Thursday morning is a write-off, and the afternoon is tiny with a gentle breeze still putting chop on the surface. The combined energy is weak, under 100.

Friday the 7th and Saturday the 8th are the same story. The swell is flat, barely a ripple. We get a few moments of glassy conditions on Friday morning and Saturday afternoon, but with waves only 1.0ft, it's flat as a pancake. The energy is just 21 (Friday morning) and 42 (Saturday afternoon). There's absolutely nothing to ride.

The whole first week is a total bust. The swell is almost non-existent, and when there is a tiny pulse, the wind is either wrong or blows it out. The only break in the whole file is Harlyn, and it's either inconsistent or not breaking at all.

The second week offers a little more swell, but it's still a no-go. On Wednesday the 12th, we get a clean session in the morning with a light cross-offshore breeze and 3ft swell from the west. The combined energy is a moderate 142, and the 9-second period gives it a bit of shape. Technically, it's surfable, but the conditions are described as "very ordinary." For a beginner spot, it's just not exciting.

Thursday the 13th sees a jump in swell to 5ft in the morning and 6ft in the afternoon, with the combined energy getting up to 430. But the wind is moderate and cross-off or cross-shore, keeping the surface messy. The period is short too, at 8 seconds, so it's not going to have any punch.

The weekend of the 16th and 17th brings the biggest swell of the forecast, with waves hitting 7ft on Sunday the 16th. The combined energy is a strong 516. But the wind is a fresh cross-onshore, making it choppy and lumpy. For a beginner break like Harlyn, that's not a good look. Even the clean wind days on the 17th and 18th are ruined by the fresh breeze, and the swell is dropping.

The final days, the 19th and 20th, are a complete dud with strong winds and a messy sea state. The swell is small and the wind is either cross or onshore, creating a proper mess.

Honestly, if you're looking for a paddle, you're out of luck. The wind and swell never align for clean, quality waves. The setup looks more interesting for a kite session than a surf. I'd be checking back in a few days – forecasts can always change, but right now, this is a blank run.

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.
