The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this run of forecast for our patch is a tough one to call. We’re looking at a solid 16-day window, but for the most part, it’s a waiting game. The swell and the wind just aren't lining up to give us anything rideable for a good long stretch. We’ve got a big gap of quiet, messy conditions ahead before things might finally turn on.
First up, there’s nothing on the cards for the next week. From the 8th right through to the 21st, it’s a complete blank. The swell is tiny—we're talking ankle to knee-high at best, with weak energy readings mostly in the low double digits. The wind is all over the shop, mostly cross or onshore, and even when it does go offshore, there’s just no power in the water to push around. So, mark those days off. It’s gonna be flat and frustrating. A lot of staring at the horizon, I reckon.
Now, the first real chance we get is on Saturday the 22nd. The energy finally kicks in. We've got a moderate swell showing up, with the combined energy climbing to 535 in the morning, jumping to a strong 873 by the afternoon. Swell heads from the west, pushing waves into the 6ft to 7ft range. But here's the catch—the wind is a strong cross-shore, blowing at 25 to 28 mph. It's going to be messy, with a cross-chop and blown-out conditions. It’s gonna be big and powerful, but it sure won't be pretty. This one’s for the experts in the lineup who don’t mind a washing machine.
Then, Sunday the 23rd holds our most significant swell event. The early morning sees the combined energy rocket to a very strong 1038, with a solid 10ft west-northwest swell. That's proper size. The period is short, at 8 seconds, and it's coming in as a cross-on from the north-northwest. Later in the day, it drops to 8ft but shifts more to the northwest, with the energy still strong at 736. The wind eases off a bit, but it's still a cross-onshore at 16 mph. This is the standout, but only for the hardcore, expert crew. It’s way over the 8ft mark, so it’s not for the faint of heart or anyone on a longboard.
So, to sum it up: the first week-plus is a total write-off. The action, if you can call it that, is all in the final two days of the window. That 7ft to 10ft swell is the big draw, but the rippable quality just isn't there with that wind. It might honestly be more exciting for the kite surfers out there than us paddle surfers. It’s a long-range call, so don't book your flights just yet—things can change. But right now, it’s looking like a whole lot of nothing, followed by a raw, powerful close-out. Keep your expectations low and your wetsuits ready.
Rusty out.

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.
