The Lowdown

Alright, let’s get into it. We’re looking at Harlyn for the next 16 days, and I’ve gotta be straight with you – it’s a bit of a mixed bag with a lot of waiting. The water temp is sitting around 65°, which feels a touch warmer than normal for the start of September, so at least the water’s pleasant.

The first few days are a write-off. We’ve got poor conditions through Tuesday, Wednesday, and into Thursday morning. Winds are cross-off or offshore, but the swell is weak and messy. The real kicker is the wind strength – it’s blowing 19 mph from the SSW on Wednesday morning, which is offshore but just too strong for it to be fun. There’s a little bump on Thursday afternoon with 6 ft of swell from the W, but the wind is cross, and the combined energy is only 447, so it’s weak. I wouldn’t paddle out for that.

The first real standout is the Saturday morning, the 5th of September. We’ve got glassy conditions with a light easterly breeze, almost no wind. The swell is a modest 4 ft from the W with a 10-second period, and the combined energy is 238. It’s not big, but it’ll be clean. Perfect for a beginner session, which is good because Harlyn is a beginner-friendly spot. Keep in mind, it’s inconsistent here, so don’t expect a pumping lineup.

The next good window is Monday the 7th. The morning shows 6 ft of W swell with a 12-second period, which is a nice long-period groundswell. The combined energy jumps to 1013, which is moderate to strong. The wind is a clean cross-off from the SW at 12 mph. This is the best on offer in the first week. The only downside is that Harlyn is a sheltered spot, so this swell might not wrap in perfectly, but it’s worth a look. The swell is over 5 ft, so it’s maybe a bit much for absolute beginners, but fine for most.

After that, things get messy again. Tuesday the 8th has a big 10 ft swell from the W, but the wind is fresh and cross, and the wave comment is poor. That’s a no-go. The whole second week is a washout until we get to the 14th of September.

Monday the 14th afternoon shows some promise. The swell is 6 ft from the W, with an 8-second period, so it’s windswell, not groundswell. The combined energy is 435, which is moderate. The wind is light and cross-off from the E at 6 mph, and the wave comment says expected good surf conditions. This is the standout of the second week, but it’s a week and a half away, so take it with a grain of salt.

The next day, Tuesday the 15th morning, has 6 ft of W swell with a 10-second period and a moderate offshore wind from the SSW at 12 mph. The energy is 693, which is solid. Could be a good session, but again, it’s long-range.

Overall, the best bet is the Monday morning and Saturday morning of the first week. The second week is a waiting game. The crowds are often at Harlyn, so expect some company on the good days.

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.
