The Lowdown
Alright folks, Rusty here. Gotta be straight with you – things are looking pretty grim for the next couple of weeks around here. We’ve got a long stretch of poor conditions ahead with very little to get excited about.
We’re looking at a solid two-week gap where the surf just isn’t worth paddling out for. From now, right through until September 5th, it’s a write-off. The wind is just too strong and all over the shop, with onshores and cross-shore winds making a mess of things. We see some moderate to strong combined wave energy coming through at times, but it's paired with poor winds and lumpy conditions. It’s a real shame because there’s some size there, with waves hitting 8 ft on August 31st, but it’s just messy and blown out.
Then, finally, we get a tiny glimmer. On Saturday, September 5th, the conditions look like they might line up. The morning is still a bit iffy with light cross-shore winds and 6 ft swell from the west at 9 seconds, but it's just marginal. The real standout is Saturday afternoon. The wind drops right out to a light breeze from the southeast, swinging cross-offshore, and the surf cleans right up. We’ve got a decent 6 ft west swell rolling in with a 10-second period. It’s not the biggest, but it’ll be the cleanest we’ve seen in two weeks. This is your window.
After that, it’s back to the grind. Sunday the 6th might have some surfable 5 ft waves in the morning with some offshore wind, but it’s nothing special. From there, we’re back into a mess of onshores and cross-shore winds for the rest of the outlook. The swell drops away into the second week, with only small, weak energy and strong offshore winds that make it hard to paddle into and keep the waves tiny.
So, keep the board in the car for September 5th afternoon at Harlyn. It’s a beginner-friendly spot, but it’s inconsistent and often crowded, so expect company. With that west swell and those light, clean winds, it’ll be the only real chance for a fun, clean session. The rest of it? Honestly, looks better for a kite than a paddle on most days. Keep an eye on the charts, hope for a change.
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.
