The Lowdown

Alright, Rusty here again. Let’s break it down in feet and miles.

First thing, the first week is a bust. We’ve got a lot of strong cross-onshore winds and messy conditions, so don’t bother suiting up until later. The water is about 65°F, which is a touch warmer than usual for this time of year.

The best chance you’ve got is on Sunday the 13th in the morning at Harlyn. There’s a 5ft west swell with a 10-second period, and the wind is light and cross-offshore. The combined energy of all swells is moderate at 422. It’s not going to be a classic, but it’ll be clean and rideable. That’s your best window.

After that, the surf fades out. We get a tiny glassy morning on Thursday the 17th with 2ft waves, but it’s weak and not much push. Then on Wednesday the 23rd, there’s a 3ft WNW groundswell with a very long 15-second period – energy at 456 – but the wind is onshore, so it’ll look better than it surfs.

All in all, no big swells, no epic conditions. Just a quiet stretch with one half-decent morning on the 13th. Keep your expectations low.

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.
