The Lowdown
Alright, Rusty here again, this time in the old numbers. Let’s break down Harlyn over the next couple of weeks, and I’ll level with you – it’s a tough watch.
Starting from Thursday the 10th, we’ve got a real dry run. Poor surf conditions stretch all the way until the morning of Wednesday the 24th of September. That’s about two weeks where the waves just aren’t playing ball. There’s some size here and there, but the wind is usually ruining it, or the quality is just flat-out bad.
The one bright spot you need to know about is the morning of Thursday the 25th of September. For the first time in a long time, Harlyn looks clean. A gentle offshore breeze from the south will smooth things out. Swell is coming from the west at about 6 ft with an 8-second period, and the combined energy is moderate at 337. It’s not gonna be a classic day, but after weeks of rubbish, it’s actually surfable. The water’s sitting around 65°, which feels a touch warmer than average for this time of year.
That Thursday morning is the only real highlight. Everything else before that is a write-off. Don’t waste your time waxing up until then. Forecasts can always shift, but right now, that’s your one chance.
Stay patient.
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.
