The Lowdown
Right then, let’s have a look at Harlyn. It’s a sheltered little beginner spot, but the next couple of weeks are looking more like a write-off than a write-up. Honestly, the first real chance of anything half-decent is a good way off. For the most part, the wind’s going to be a problem, and the swell that does make it in here is mostly messy.
We’re in for a long, frustrating stretch. From now through the 20th, there’s practically nothing worth paddling out for. The consistent theme is fresh to strong cross-shore and cross-onshore winds ruining what little swell is on offer. There’s a pulse of energy building toward the 19th, with swell hitting 8ft, but that’s from the WNW and it’s getting shredded by a 21 mph crosswind – it’s going to be a lumpy old mess, not surfable. That same weekend, the 20th sees strong breezes and messy conditions. It’s a write-off.
The one and only standout window is the morning of Monday the 21st. We’re looking at a solid, long-period groundswell from the WNW, 10ft at 13 seconds. That’s proper energy, with a ridiculous amount of power behind it. It’s big, though; over 8ft, so this is strictly for the experts. The wind is a cross-offshore, keeping it clean, and the period is long, which will help the waves shape up nicely at a sheltered spot like this. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, so you won't freeze. The afternoon drops back to 8ft and the wind goes cross-shore, making it lumpier, so get on it first thing.
After that, it drops off again. The 22nd has some knee-high leftovers with light winds, but it’s marginal. There’s a flicker on Wednesday the 23rd afternoon, with 7ft from the west and a light southeast breeze, so it could be clean, but the period is short at 8 seconds, so it’ll be a bit weaker and less organised. The 24th and beyond look poor – strong winds and dropping swell, with the final days of the outlook fading into onshore slop.
So, to be straight with you, if you’re a beginner, you’re best off staying dry for a while. If you’re an expert and hungry, set your alarm for Monday the 21st morning. That’s your one shot. The rest of the run is a long, empty gap.

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.
