The Lowdown

Right then, let's have a look at what's on the cards for Harlyn. I gotta be straight with you – it's a tough stretch ahead. There's a lot of days where the conditions just aren't coming together, and we're looking at a real lean period before anything decent shows up.

The water's running at 65°F this Monday morning, which is a touch warmer than normal for this time of year, but honestly, you won't be wanting to get in for the surf.

The first bit of any real hope doesn't show up until Saturday, the 12th of September. That morning, you've got a 3ft swell from the west, and the wind is swinging offshore from the southwest, keeping things clean. But don't get too excited – the wave energy is weak (183), and it's only being called surfable but very ordinary. It's not one to rush out for.

From there, it's back to the doldrums. Tuesday the 15th sees a bit more size, up to 5ft from the west, but the wind is onshore or cross-onshore, mucking it all up. That pattern holds until we get to the standout period.

Now, mark your calendar for Sunday the 20th of September. This is where it finally turns. We've got a solid west swell coming in at 6ft on the Sunday morning, with a period holding at 12 seconds – that's proper groundswell, giving you some shape and power. The wind is light offshore from the southeast, a gentle breeze, so it'll be clean. The combined energy is strong (864), and the forecast says expect good surf. Sunday afternoon keeps it going with a 6ft west swell, light offshore breezes from the south-southeast, and clean conditions (720). This is by far the best on offer, but it's over a week away, so it's promising, but not locked in just yet. Harlyn is an inconsistent spot, so when it does line up, you need to be ready to move. Crowds are often a problem here, so expect company if the forecast holds.

After that, Monday the 21st brings a northerly change with onshore wind and a short, weak 6ft swell at 6 seconds – that's junk. The rest of the window into the 22nd is poor, with onshore winds and messy conditions. The setup for most of this period looks more interesting for kite surfing than paddling.

Overall, the first week and a half is mostly a write-off. Hang in there for that Sunday the 20th – that's your best shot.

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.
