The Lowdown
Alright, let’s break this down. It’s been a bit of a mixed bag, lots of cross-shore junk, but there are a couple of windows where it’ll be worth the paddle.
That Sunday the 20th is the day to get wet. We’re looking at a glassy morning, almost no wind at 5 km/h from the ENE, and some clean head-high swell rolling in at 1.4m from the W on a 10-second period. The energy reading is moderate at 440. It’s not just surfable; it’s going to be fun, clean, and with the water temperature pretty much right where it should be for this time of year (around 60-61°F), you’ll be comfortable without a ton of rubber. If you can only pick one day, this is it.
Now, if you want a bit more power, circle Tuesday the 23rd. The swell is up, a solid 1.6m from the WNW with a longer 14-second period, and the energy is pushing 874. The wind is cross-off from the SE at 30 km/h, which is going to hold the faces up but will make it a bit more of a chore. It's got some grunt to it, a more challenging wave for the better surfer in the water. It's not as clean or as easy as Sunday, but it's got more of a pulse.
For the rest, it’s a waiting game. The 21st and 22nd have tiny, weak waves that are mostly a waste of time. It goes pretty much flat from the 25th through the 27th, so you can leave the board at home. There was a junky, onshore mess on the 28th with 1.7m of swell but blown-out conditions—that one’s for the masochists. And the 30th brings a bigger 2.3m, but it’s cross and messy, so you’ll be fighting it more than surfing it. That far out, the forecast will change, so don't bank on it.
So, the short of it: Sunday the 20th is your clean, glassy, fun-wave day. Tuesday the 23rd is for when you want something with more size and power. The rest is just noise.

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.
