The Lowdown
Alright, Rusty here. Let's take a look at what we’ve got on the table for Harlyn over the next couple of weeks. I’ll be straight with you – it’s a bit of a tough stretch, but there are a couple of windows if you know when to paddle out.
Right off the bat, the outlook is quiet. For the first few days, through to Monday the 11th, it’s pretty much a write-off. We’re looking at tiny, weak swells, mostly under 1 ft, with periods under 9 seconds. The wind is mostly cross or onshore, and the combined energy is barely registering (15 to 53 in the bracket). There’s nothing worth getting wet for.
On Tuesday morning the 12th, things start to hint at life. The swell picks up to 3 ft from the west with a period of 10 seconds. What’s really interesting is the combined energy jumps to 126 (moderate), and morning glass-off conditions. It’s very ordinary surf, nothing flash, but the glassy surface makes for a clean, if small, session. The afternoon holds similar, with 3 ft and glassy conditions. For a sheltered spot, that’s your best bet early on.
Then we hit a dead patch again. Wednesday the 13th through Monday the 18th is dominated by onshore winds (N, NW, NNE) blowing hard, often 12–22 mph, making a mess of the 3–4 ft west swell. The energy picks up to 234 and 239, but it’s all wind-blown. Kite surfers would have a field day, but for a paddle surfer, it’s a no-go. Tuesday morning the 19th offers a tiny 0.3 ft swell with a very long 17-second period from the SW—pretty much not surfable.
The second week is sparse. From Wednesday the 20th, we see a bump in north swell around 3 ft to 5 ft, but the wind is relentless from the north and northwest, gusting to 19 mph. It’s choppy, messy, and the energy is strong (193 on Friday the 22nd), but the quality is poor.
The one standout is Saturday morning, the 22nd of August. Now, this is a full nine days out, so it’s still a maybe, but here’s the picture: a S wind at 15 mph, offshore, blowing clean. The swell is 4 ft from the north, period 6 seconds. The combined energy is 144 (moderate). It’s described as “surfable waves but very ordinary conditions” really just means it’s surfable, not epic. For Harlyn, that offshore wind is a major positive, cleaning up the face. The crowd profile here says ‘often’ busy, so expect company. It’s a beginner-friendly break, so 4 ft is fine for most.
Other than that, the surf remains underwhelming. The water is sitting at 66°F, which is a touch warmer than usual for this time of year—almost 4°F above normal, so you can ditch the thick wetsuit.
Honestly, it’s a quiet run for Harlyn. If you’re desperate, aim for the glassy morning on the 12th, or the offshore window on Saturday the 22nd. 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.
