The Lowdown

Alright team, Rusty here. I've been staring at the charts for Harlyn and I've got to be straight with you: it's a pretty grim outlook for the next couple of weeks. We've got a long stretch of small, messy surf and crummy winds, so you'll want to keep your expectations on the floor.

Looking at the whole 16-day window, the first recommendation doesn't even show up until Monday the 12th, and even then it's a marginal call. Most of this period is a write-off for a proper surf. We're looking at a whole lot of nothing for a while.

The First Wave (Monday morning? No, Tuesday afternoon on the 12th)
The first time it even looks like you could get wet is on Wednesday, the 12th, in the afternoon. That's a long three-day gap from now with nothing on offer. The swell is small at 3ft, but what makes it interesting is that the wind goes glassy. It's a quick window of clean conditions before the onshores kick back in. It's surfable, but very ordinary. The energy is moderate at 110. If you're a beginner, this is your only realistic window for a very long time, honestly. It's about as close to a doable session as we get in this whole extended forecast.

A Flicker of Hope Thursday 13th
Thursday the 13th sees the swell push up to 4ft but the wind goes cross-onshore from the NW and it chops it up. It's a clean miss. The energy is up to 267, which is moderate, but it's a messy 4ft and the wind just ruins it. Not worth it.

The Long Haul
From there, it's a pretty bleak picture. We've got a solid week and a half of small, onshore, and generally choppy conditions. The swell stays under 4ft, and all those cross-onshore and onshore winds just keep the surface messy. We get some period in there, like a 13-second one on the 12th, but there's no size behind it.

A Potential Standout (Far Off)
There is one thing that catches my eye, way out on Tuesday the 25th. We see the swell jump to 4ft in the morning and 5ft in the afternoon, coming from the west. The wind is forecast to be cross-offshore from the SW, which would clean it right up. The energy is a solid 307-332, which is the strongest we see all window. This has the potential to actually be decent, but it's a long way off. Treat it as promising but a long shot. It's on the bigger side for Harlyn, so if it does come together, it could be a bit much for beginners.

Bottom Line
For the next 16 days, the pickings are incredibly slim. The best bet for a beginner is that glassy window on the afternoon of Wednesday the 12th. For everyone else, you're waiting for that Tuesday the 25th, and hoping the forecast holds. It's a tough stretch, but that's the nature of it sometimes. Hang tight.

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.
