The Lowdown

Alright, Rusty here. Let’s talk about what’s ahead for Harlyn.

Honestly, the next couple of weeks are looking pretty grim for any kind of decent surf. This is a tough stretch for a sheltered spot like Harlyn – we need the wind and swell to line up, and they just aren’t doing it. There’s a long, drawn-out period of poor conditions, with only one morning that might offer a glimmer of hope, and even that’s a bit of a question mark. If you’re desperate for a paddle, that’s your best shot, but I wouldn’t get my hopes up.

Let’s break it down. We start this Sunday, the 13th of September, with some waist-high-ish swell around 5 feet out of the west, but a strong southwesterly cross-offshore wind is messing with the shape. The water temp is 64°, which is a touch warmer than normal for this time of year (anomaly of 3°). The combined wave energy is moderate (448), but the forecast calls it marginal, and I’d agree – it’s not worth the effort.

From Sunday afternoon right through to Saturday the 19th, it’s all poor. The wind stays cross or onshore, the swell is messy, and the period is short and weak. On Tuesday the 15th, a fresh WNW wind kicks up 7 feet of windswell, but it’s a lumpy, cross-onshore mess. The wave energy jumps to 522 (still moderate), but the quality is junk. Wednesday the 16th sees the biggest energy of the whole run (821), but again, it’s cross-onshore and ugly.

The only real standout is the morning of Sunday, the 20th of September. We’ve got a 5 feet swell from the WNW with a period of 10 seconds – a decent groundswell that should have some shape. The wind is light southerly and offshore, which is a major positive. The combined energy is moderate at 531, and the forecast actually says “expect good surf conditions” for that morning. This is the one to circle on your calendar. Keep in mind Harlyn is inconsistent, so a decent window is a rare treat. The crowds here are often, so expect some company if you go.

After that morning, it goes back to poor. Monday the 21st has a smaller, cleaner looking swell (3 feet, 13 sec period, 283 energy), but the wind is messy. From Tuesday the 22nd onward, the swell drops off hard. By Thursday the 24th, we’re looking at knee-high dribble (1 foot) with almost no energy (30). The week of the 27th is flat and windy. Even a glassy morning on the 27th with 2 feet isn’t going to do anything.

So, to sum it up: a long, dry spell with one possible bright spot on the morning of the 20th. It’s not a classic Harlyn run, but that offshore window could surprise you. Keep an eye on the wind that morning, and if it holds, get in the water.

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.
