The Lowdown
Alright, let’s switch to imperial for the stateside crew, but it’s the same sorry story for Harlyn.
The first chance to even look at the water is on Friday, July 17th, and it’s not pretty. The water temp is 64°F, which is a touch warmer than normal for this time of year, but that’s the only highlight.
From the 17th through the end of the month, it’s a real dry spell. The waves are tiny, mostly under 3ft, with onshore and cross-shore winds ruining any chance of a clean face. The north and north-northwest swells are all wrong for Harlyn’s preferred west-northwest direction, and the periods are short – 5 to 8 seconds – so you get weak, bumpy, and uninviting surf. The combined energy of all swells directed here is mostly in the 60s and 70s (moderate energy at best, mostly weak), and every single time slot is marked as “poor surf conditions.” You get a tiny window on Tuesday morning, July 21st, with glassy conditions and a 3ft swell from the north-northwest, but with a 6-second period, it’s barely a ripple. That first week is a total loss.
The only faint glimmer on the horizon is Tuesday afternoon, July 28th. We’re looking at a 2ft swell from the west-northwest with a 10-second period, giving a combined energy of 132 (strong wave energy). The wind is cross-off, so the surface should be clean. But that’s over a week away, and it’s still a very small wave. For a spot that’s inconsistent and sheltered, it’s a maybe, not a definite. And Harlyn can be “often” crowded, so if that tiny window does line up, you won’t be alone.
The final week of the forecast into early August falls apart completely. More small westerly swells, strong winds, and rain showers. The combined energy drops to the teens and single digits (weak wave energy).
This is a classic quiet period for this area. Most of the time, the setup looks more interesting for kite surfing than paddle surfing. Forecasts can change, but based on what I’m seeing, it’s a good time to clean the wax off your board.

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.
