The Lowdown
Alright folks, Rusty here. Let’s have a look at the local surf outlook for our little corner of the coast. I gotta be straight with you—it’s a pretty sad picture for the next couple of weeks. The good news is we’ve got one break to keep an eye on, but the bad news is it’s mostly going to be a waiting game.
We’re looking at Harlyn as the only option, and it’s a tough one. This is a sheltered, beginner-friendly spot, but it’s also inconsistent, so it takes a proper run of conditions to fire. For the vast majority of the 16-day window, the surf is just poor—weak, choppy, or blown out. You’ve got a long gap of nothing worth paddling for from now until almost the very end.
Things finally start to look a little more interesting around Thursday, August 27th. There’s a pulse of energy coming in. On the Thursday morning, we’re looking at a clean 5ft swell from the west with an offshore wind from the southeast. The combined energy is solid at 372, and with that offshore wind, Harlyn should be clean and peeling. This is the standout of the whole run—the cleanest, most powerful swell we’ll see.
Friday morning, August 28th is also worth a mention as a secondary option. The swell drops back to 2ft, but it’s from the west-northwest with a light offshore breeze from the south-southwest. The wave energy is low at 93, but it’s clean, and that’s more than we can say for most of the forecast. It’s a good time for a longboard or a foamie.
The water temp is about average for this time of year, nothing unusual. Just remember, Harlyn can get crowded when it’s good, especially with that offshore wind, so get in early.
So, to wrap it up: the first two weeks are a write-off. Hold out for Thursday, August 27th for the best chance at a proper session, and maybe a gentle paddle on Friday morning if you’re desperate. The long-range call for the big day is promising but not locked in yet, so keep your fingers crossed.
Stay stoked,
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.
