The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this next stretch is a tough one for the Harlyn area. We're looking at a long, flat spell to kick things off, with nothing really worth paddling out for until the second week of the window.
From now through the 11th of August, it's basically a write-off. Tiny, weak waves and onshore or cross-onshore winds making a mess of things. Thursday the 6th and Friday the 7th are showing a poor 3ft and 1.0ft of weak, short-period windswell, chopped up by the wind. The weekend is no better, with Sunday the 9th bringing onshore winds straight into the beach. A real bummer for the first week, with almost a full week of nothing to get excited about.
Things start to look a little more interesting around the 12th of August. We finally see a pulse of energy coming through on Wednesday morning. The swell bumps up to 3ft from the W, with a period of 10 seconds, and the wind is light and cross-offshore. The combined energy jumps to (183), which is a step in the right direction. It's still pretty ordinary, but it's surfable. The water temp is about average for the time of year, so no shock to the system.
Then, Thursday the 13th of August is the standout. Early morning, it's glassy calm with a 4ft swell from the W, 10-second period, and a combined energy of (235). That's the best conditions we're going to see. Harlyn is a sheltered beginner spot, so with that swell size and those clean, glassy conditions, it'll be a fun little wave for the beginners and longboarders. The wind is dead calm, so it'll be smooth as silk. Just be aware it's inconsistent, so you might have to wait for the sets.
The days after that are a mixed bag, with some clean windows but the wind often swinging around and messing with the shape. The 16th of August, a Sunday, has a bit of clean surf in the morning with a gentle offshore from the SSW for a 4ft WSW swell, giving it a score of 1 out of 10 for surfable but ordinary. It's worth a look if you're desperate, but it's nothing to write home about.
The swell gets a bit of a spike on the 17th of August, hitting 5ft, but it's a short-period, messy windswell from the N with a fresh cross-onshore wind. That's not going to be pretty. A couple of the later days, like the 19th and 20th, have clean cross-offshore winds but the swell is small and the energy is moderate at best, with the wind also picking up significantly.
So, the call is clear: if you want the best of a poor run, you're looking at the morning of Thursday the 13th of August. It's the only time in the whole 16-day window where the stars align for a clean, glassy session. Don't hold your breath for anything else.
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.
