The Lowdown
Alright folks, Rusty here. Let’s have a look at what we’ve got coming up for Harlyn. I’ll level with you straight up: we’re in for a tough run. The next 16 days are mostly a write-off for any kind of decent surf, but there might be one little window if you’re desperate to get wet.
The whole stretch starts off quiet and pretty much stays that way. There’s a massive gap with no real surf to speak of. The first few days are just poor with small, weak, and messy conditions. The swell energy is low, and the winds keep messing things up.
It looks like we finally get a pulse of swell arriving around Wednesday the 19th of August, but the wind is going to be howling from the west at 19 mph. That’s fresh wind, and it’s going to chop everything right up. The swell comes up to 5 ft out of the WNW, but with that cross-off wind making it a bit lumpy, it’s not really a paddle-friendly setup. That’s more of a kitesurfing kind of day for Harlyn.
If you’re really holding out, the best chance comes on Friday the 21st of August. The morning window is the one to look at. We’ve got a 4 ft swell from the W, with a 8 second period, and the combined energy is moderate. The wind turns light and easterly – a cross-off breeze that should leave the surface clean. That’s about as good as it’s going to get for a paddle. Still a bit small and ordinary, but at least you might catch a few clean ones in the morning. Keep an eye on the crowds at Harlyn; they can be common there.
The water temperature is sitting at 67°F, which is about 4°F warmer than usual. That’s notably warm for this time of year, so you won’t need a thick wetsuit.
Beyond that, the rest of the run is just small windswell and cross-onshore chop. We drop right back down to under 2 ft from the 22nd onwards, with no real energy or clean conditions to write home about. It’s a bleak second week, with most days showing poor surf.
So in short, it’s not great. There’s a glimmer on Friday the 21st morning for some small, clean waves, but the rest is a rough ride. Keep the board waxed and wait for a better forecast.
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.
