The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Harlyn.
To be straight with you, the next couple of weeks are looking pretty grim. There’s a big gap of nothing useful at the start. The first proper session that’s even worth a mention is a bit of a stretch, and honestly, for the most part, this is a quiet run for the area. It’s the kind of blank spell that happens here, but it never stays poor for long—forecasts can shift.
The only real standout in the whole 16-day window falls on Monday, 7th September. The morning session at Harlyn sees a solid 7ft swell from the W, with a long 13-second period groundswell. That’s proper energy moving through (1632). The wind is a cross-shore from the W at 16 mph, which is okay, but it’s a moderate breeze that’ll bring a bit of cross-chop. It’s not perfect, but it’s the most size you’ll see. The afternoon is slightly cleaner with a cross-offshore breeze and a 7ft swell, still from the W, with a 12-second period (1266). That’s your best bet for a wave, but it’s a touch on the bigger side—more suited to surfers with some experience. The water temperature is sitting at 64°, which is a touch warmer than normal for this time of year.
After that, it’s a slow decline. The middle of the week (Tuesday 8th to Thursday 10th) shows some waist-to-chest high swell, but the winds are messy. By Friday 11th, it’s a fresh cross-onshore with 22 mph winds, lumpy and choppy. From Saturday 13th onwards, the swell drops right off. You’re looking at leftovers under 3ft, and by the second week, it’s mostly flat, knee-high dribble with onshore winds or full-on offshore winds that kill any shape. The end of the run (17th to 20th September) is a total write-off.
So, if you’re hanging for a wave, your best shot is Monday 7th September. Go for the afternoon. It’s not epic, but it’s the most you’re gonna get.
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.
