The Lowdown
Right, folks. Rusty here. Let's have a look at what's on offer for Harlyn over the next couple of weeks.
First up, Wednesday morning the 12th. It’s small, with clean 3ft swell from the west, and the water is a good 67°. The combined wave energy is only weak at 125, and it’s an inconsistent spot as it is, so don't expect much. The water temperature anomaly is 4°, which is much warmer than normal for this time of year, making a paddle a bit more pleasant. The wind is a light cross-off from the ESE, so it's tidy, but the swell's just too weak to get excited about. The afternoon holds a similar story, with a small 3ft west swell and a clean offshore breeze, but it’s all a bit ordinary.
The bad news is everything after that goes straight downhill. From Thursday the 13th right through to Tuesday the 27th, every single session is rated as poor surf conditions. There are no standouts, no hidden gems. The swell does try to pick up at times, like on Tuesday the 18th with 5ft from the west, but it’s accompanied by a fresh, lumpy crosswind, so it's messy. A couple of days later, on Thursday the 27th afternoon, there’s a pulse of 3ft west-northwest swell with a period of 11 seconds and a combined energy of 380, which is a moderate to strong reading. But again, the wind is a fresh cross-shore, ruining the shape.
Because Harlyn is small, inconsistent and exposed, it’s just not firing within this window. This is a real dry spell for the area. To be honest, with the wind all over the place and very ordinary wave quality, you’d probably find more fun on a kite than a surfboard round here. This blank run is pretty normal for Harlyn when the conditions don't line up. Forecasts can change, but for now, keep your gear in the van.
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.
