The Lowdown
Alright folks, Rusty here. Let’s get real about what’s on offer for the next couple of weeks. Gotta be honest, it’s a pretty grim outlook for a while. We’ve got a long stretch of nothing really happening.
The water temp at Harlyn is sitting at 66°, which is a touch warmer than normal for this time of year, so at least that’s a small comfort.
The first few days are a write-off. The swell is tiny and messy, with cross-shore or onshore winds hurting any chance of a wave. It’s not until the afternoon of Wednesday the 12th that we see a glimmer of hope. The swell picks up to 3ft from the west, but the key thing here is the wind goes glassy. The combined energy is moderate (142), but the waves are just surfable, not exciting. It’s the best we’ve got so far, but it’s ordinary.
Thursday the 13th brings a bit more size, with 4ft from the west, but the wind is onshore or cross-shore, and the energy jumps up (277), but the conditions are poor. It’s a no-go.
The second week doesn’t offer much to get excited about, but keep an eye on the morning of Monday the 24th. We’ve got a 5ft swell from the west with a light cross-onshore breeze. The combined energy is strong (432), and the period is 8 seconds. It’s a bit of a lumpy prospect, but it’s the biggest swell of the whole period. If you’re an expert and don’t mind a bit of chop, it might be your only real chance for a wave.
Honestly, for most of the 16 days, the surf is too small, too windy, or just plain poor. The setup looks more interesting for kite surfing than paddle surfing on many of those days.
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.
