The Lowdown

Alright mate, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

Right off the bat, I’ll be straight with you – this is a tough stretch. The first week and a half is looking pretty grim, with no real surf on offer until the final few days. From now until late August, Harlyn is barely flickering. The swell is tiny, the wind is messy, and the water is sitting at 66°F, which is much warmer than usual for this time of year – a good 4°F above normal. That’s a pretty notable anomaly, so you’ll be in for a warm paddle if you do go out, but don’t expect much in the way of waves.

The first real glimmer of hope doesn’t show up until Thursday, August 27th, in the afternoon. We’ve got a clean offshore wind from the south at 12 mph, with 5ft swell from the west, a 10-second period, and moderate wave energy (420). It’s still not a standout, but it’s the first time conditions look even close to surfable. That’s a good sign for experienced surfers who don’t mind a bit of a wait.

Then there’s a gap of a few days with nothing much again – wind mostly onshore or cross-shore, lumpy, and poor.

The real standout, if you’ve got the patience and the skill, is shaping up for Thursday, September 3rd. In the afternoon, Harlyn sees a fresh offshore breeze from the SSE at 19 mph, with 8ft swell from the WSW and a 9-second period. The combined energy is strong – 1304. That’s a decent push of power, but for beginners, it’s going to be heavy and too much. This is expert-only territory. The wind is offshore, so it’ll be clean, but the size and power mean it’s not for the faint-hearted.

Overall, it’s a long dry spell with one late spike that’s worth circling on the calendar. Don’t hold your breath for the first week, but if you’re a seasoned local, that September 3rd afternoon might just deliver.

Stay keen, 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.
