The Lowdown
Alright folks, Rusty here. Let's get into it.
Looks like we're in for a tough stretch at Harlyn. The whole 16-day window is a bit of a write-off, honestly. There's a solid run of poor surf conditions, mostly thanks to strong winds being all over the place and the swell being a messy mix. From the 14th right through to the 29th, there’s no day where it all clicks for a proper session.
We kick off on Monday the 14th with a weak 4ft swell from the west, but a moderate cross-offshore breeze is keeping things clean, even if the energy is low (200). The water temp is 64°, which is a touch warmer than normal for the time of year. By Tuesday the 15th, the swell jumps to 6ft from the WNW, but a fresh breeze (35 km/h) turns it into a lumpy, cross-onshore mess. Not the kind of day you paddle out for.
Wednesday the 16th brings the biggest combined energy we see (946), with a 7ft west swell but it’s again cross-onshore and lumpy. The period is up to 10 seconds, but the wind just kills it. Thursday and Friday aren't much better, though Friday afternoon sees a nice clean cross-offshore breeze and a 5ft swell with a long 12-second period (588 energy). It’s surfable, but still just ordinary.
After that, it fades. From Saturday the 21st onward, we’re looking at tiny waves, mostly under 3ft, with very weak energy readings often below 200. There’s some glassy mornings on the 22nd and 23rd, but the swell is barely a ripple. The 29th of September has an interesting looking 3ft swell from the WNW with a very long 14-second period and clean offshore winds, but that kind of long-period groundswell needs a reef or point to work, and Harlyn's a sheltered beach. The energy is moderate at 266, but in reality, it’s a tease. It’s going to be small and inconsistent.
Basically, for the first week, the wind is our enemy, and the second week just doesn't have the size. If you’re desperate, the cleanest conditions are on Friday the 18th afternoon and some of the glassy mornings in the second week, but you’ll be fighting for scraps. When the wind is strong and the quality is poor on a beach setup like this, it honestly looks more suited to a kite session than a paddle. There's nothing here to get excited about.

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.
