The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer at Harlyn over the next couple of weeks.

Straight up, I gotta be honest with you – this is a tough run. The forecast is a long, quiet stretch with hardly anything to get excited about. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, but that’s about the only good news.

We’re looking at a gap of several days with no real recommendations. The first few days, from Thursday the 3rd right through to Monday the 7th, are all blown out or messy. You’ll see waves around, but the wind is just ruining it. Thursday morning has 5ft of west swell at 8 seconds, but that 16 mph cross-off wind is making it a chore, not a joy. The combined energy is weak (287). Friday the 4th bumps up to 7ft, but with a cross wind and a lumpy cross-chop, it’s not worth paddling out. That 707 combined energy shows there’s power, but it’s all over the place.

Saturday the 5th is a bit of a tease. The swell drops to 5ft, but the period stretches to 11 seconds, which is a nice long period groundswell. The problem is the wind is cross-on, making it bumpy. The combined energy is moderate (476). Still, it’s not clean enough to call it a goer. Sunday the 6th is tiny, with only 2ft and a weak 85 combined energy. Not happening.

Now, Monday the 7th morning is where things get interesting, but only for the brave. We’ve got a solid 8ft swell from the west with a long 13-second period. That’s a lot of water moving, and the combined energy is very strong (1796). That’s too big for beginners, and even for most, that 19 mph cross-on wind will make it lumpy and hard to handle. Only for experts.

The rest of the first week and into the second week is a mix of cross-off and cross winds with waist-high slop. Tuesday the 8th has 7ft, but again, fresh cross-onshore winds ruin it. The combined energy is moderate to strong (766) but it’s just not clean. Wednesday the 9th drops to 5ft and the wind goes cross, but it’s still a messy cross-chop.

We finally get a tiny window on Saturday the 12th. The morning shows 6ft from the WNW with a cross-off wind and a clean surface. The period is short at 7 seconds, so it’s a bit weak, but the combined energy is moderate (361). It’s surfable, but very ordinary. The afternoon is better with 5ft and a 10-second period, giving it a bit more grunt (455 combined energy), and still clean. This is the best of the bunch, but it’s still just marginal.

After that, Sunday the 13th is tiny and ordinary, and then Monday the 14th and Tuesday the 15th have waist-high swell with onshore winds, so it’s a no-go. Wednesday the 16th is the only other standout, but it’s small. The morning has 3ft west swell at 10 seconds, but the wind is glassy – that’s a major positive. The combined energy is weak (205), but it’ll be clean. The afternoon is even smaller at 3ft, but still glassy. Not a wave you’d drive for, but if you’re local and desperate, it’s the cleanest of the whole run.

The last few days of the forecast, from the 17th into the 18th, are back to small and windy. Nothing to save the run.

So, to sum it up: the best on offer is the Saturday the 12th, with a slight edge to the afternoon. It’s clean, waist to chest high, and has a bit of a longer period. The other small chance is Wednesday the 16th morning for a glassy but tiny session. Honestly, keep your expectations low and maybe save the wax for another time.

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.
