The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for our little corner of the coast.

Truth be told, the next week and a half is a bit of a grind. We’ve got plenty of swell on the charts, especially towards the end of August and into early September, but the wind just isn’t playing ball for most of it. It’s one of those stretches where the ocean’s got energy, but it’s messy, blown-out, and hard to love. The only real standout that’s got me excited is a little window on the 4th of September, and then a big, raw swell later on the 7th that’s only for the brave.

We’re looking at Harlyn for this whole run. It’s a beginner-friendly, sheltered spot, so it doesn’t take much to make it work, but even here, the conditions are a struggle.

The first real surfable day that’s worth paddling out for is Thursday, 4th September. The morning is the one to circle. We’ve got a clean 2 ft swell rolling in from the west with a 10-second period, moderate energy (463). The wind is glassy - dead calm - which is a huge positive for this break. The water temperature is about average for the time of year. It’s small, but clean, and for a spot that’s often inconsistent, this is your best bet for a fun, easy session. Expect crowds to be possible.

Before that, from the 26th of August right through to the 3rd of September, it’s pretty much a write-off. The swell is either too small, or the wind is howling cross-off or cross-shore, making it all poor. Saturday the 29th sees a jump in size to 8 ft, but with a near gale blowing, that’s just a washing machine. Not for a paddle board.

Then we jump to Monday, 7th September. This is a big one, but it’s not for everyone. The morning shows a solid 12 ft west swell, with a very high energy reading (2310) and a good 10-second period. It’s blowing cross-off, so it’ll be clean. But listen, at that size, with the period and the direction, Harlyn is going to be a heavy, powerful wave. This is strictly for experts only. Beginners and intermediates should give this a wide berth. The afternoon drops to 10 ft, but the wind picks up, so the morning is the only window.

After that, the 8th and 9th of September see the swell drop back down, but the wind is cross-shore or light, so it’s back to the small, ordinary stuff.

So, to wrap it up: the standout is the glassy morning of the 4th of September for a clean, small wave. The 7th of September is a big, expert-only session for those who can handle it. The rest of the 16 days is a waiting game.

Stay salty.
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.
