The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks at Harlyn. It’s been a bit of a mixed bag, but I’ll walk you through the whole stretch.

The pattern starts off with a bit of a wait. The first sniff of something rideable comes on Saturday, the 5th of September, but honestly, it’s a bit of a struggle. We’ve got a 5ft swell from the west, with a long 11-second period, but the wind is a cross-on breeze from the northwest, putting a bit of a chop on it. The water is a touch warmer than normal for this time of year, sitting at 64°F. The energy is moderate (552), but it’s just messy. The morning is the best of a bad lot, but the afternoon drops off even more. The following Sunday, the 6th, is a write-off for surfing – the swell is tiny and the wind is howling.

Monday, the 7th of September, looks like the standout, but there’s a big caveat. The swell jumps up to 7ft from the west, with a very long 13-second period. That’s proper groundswell energy (1632), and it’ll be powerful. However, the wind is a moderate cross-shore from the WNW, which will put a chop on it. For the experienced crew, this is the one to circle. The 7ft in the afternoon cleans up a bit with a cross-off breeze, but it’s still a hefty size. This is expert territory; the power and the period will make for some heavy, walling waves, but it might be too much for beginners. The long period and that size will be a handful, especially if it’s breaking too straight.

After that, the rest of the first week and into the second is a long, frustrating stretch. From Tuesday the 8th through to the 13th, the wind is in a terrible direction, mostly cross-onshore, and the swell is either too small or too messy. The energy drops right off (down to 97 on Thursday the 10th). There’s a brief moment on Thursday the 10th and Friday the 18th where the wind goes offshore, but the swell is tiny (3ft to 3ft) and the period is short. We’re looking at long gaps of nothing much happening.

The real standout, if you’re a strong surfer, is that Monday the 7th. The 7ft at 13 seconds from the west has the potential for some serious, powerful walls, but the chop will be a factor. The morning is the biggest, but the afternoon is cleaner. The other option is the very end of the run, on Saturday the 19th and Sunday the 20th. The swell is small (2ft to 2ft) but the wind is light and clean, coming from the south. That’s a glassy, small-wave day for the longboard or a fun little fish. The energy is weak (87 to 105), so it’s not going to be pumping, but it will be clean.

So, to sum it up: the big one is Monday 7th for experts only, and the very end of the run (19th-20th) offers a small, clean window for the logs. The rest is a long stretch of wind-blown nothing. Harlyn (Cornwall) is a sheltered spot, so it takes a specific angle to get it right, and this forecast doesn’t give us many of those. It’s a bit of a tough outlook, but that’s the way it goes sometimes.

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.
