The Lowdown

Alright folks, Rusty here. Let’s have a look at the next stretch. Honestly, it’s a tale of two halves for us. The first week and a bit is a write-off for any decent paddle surfing. But there’s a little window of hope peeking through around the 5th of September that looks like it might just save us.

To start, the water’s sitting at a warm 66°, which is a touch warmer than normal for this time of year. That’s something, at least. The first few days are grim. Through the 27th and into the 28th, we’ve got small, weak swell – nothing over 2ft – with cross-off winds that aren't doing us any favors. It’s just poor, weak surf. Then the 28th afternoon kicks up a bit of size, with a 6ft swell, but the period is a short 7 seconds, and it’s lumpy and poor. The energy is moderate (348) but completely wasted.

The 29th sees the swell build. Saturday morning has 6ft of short-period SW slop, and by the afternoon it jumps to 10ft with a strong breeze and a huge energy reading of 1592. That’s strong energy, but the quality is still poor – it’s a mess. Sunday the 30th keeps the swell around the 6ft to 7ft mark, but it’s still cross-off and, frankly, poor. We roll into the 31st with the wind turning cross-onshore and lumpy, with 8ft on the Monday morning. This is all just churned-up, blown-out conditions. There’s plenty of water moving, but it’s not surfable.

The first of September remains poor, and the 2nd finally gives us a little glimpse. The wind goes offshore, and the water is clean, but there’s only a weak 2ft swell on the morning, with an energy of just 97. It’s surfable but very ordinary. That afternoon, the swell bumps to 3ft but the wind freshens, so it's still not worth getting wet for.

The 3rd and 4th see the swell come back up – 7ft to 8ft – but it’s cross-shore with a lumpy cross-chop. We’re looking at poor conditions all over again, with strong breezes. Nothing good.

But then, here’s the standout. The 5th of September. Saturday morning, the wind drops out to nearly nothing – an ESE light air at 3 mph. There’s a clean 5ft swell from the west with an 11-second period. It still won’t be amazing, but it’s the first time it’s actually looking surfable. The afternoon looks even better. The wind goes light offshore from the SSE, and the swell jumps to a solid 10ft. The energy is strong at 1186. This is the one true standout of the whole window. The conditions are forecast to be very good. Just remember, this is Harlyn, and it’s an inconsistent spot, so you gotta be there when it decides to break.

After that little taste, it fades. The 6th and 7th of September see the swell back down to 4ft – 7ft with the wind picking up again, cross-off but just not clean enough. The rest of the second week, from the 8th through the 11th, is a slow decline into small, onshore, and choppy conditions before fading into nothing. The energy drops off, and the wind turns straight onshore for a couple of days.

So, bottom line: it’s a long, frustrating run of poor conditions, with one clear window on Saturday the 5th of September. It’s over a week out, so treat it as promising, not certain. But if the forecast holds, that Saturday afternoon might just be the one to make it all worthwhile.

Stay stoked.

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.
