The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the Harlyn area over the next couple of weeks.
Straight up, it's a bit of a rough stretch for surfers. The forecast is pretty grim for the first two weeks, with a whole lot of "poor surf conditions" flagged. We're looking at a long dry spell from the 8th of August right through until the early hours of the 21st of August. That's nearly two weeks of tiny, weak waves with lousy winds. The swell energy is mostly in the double digits (19 to 125), just a weak mush. The water temp is about average for the time of year, which is the only thing that's normal.
The first real glimmer of hope doesn't come until Friday the 21st of August. The morning starts off with a clean 3ft swell from the west, with a light southerly offshore wind. The energy is still weak (92) and the period is a short 5 seconds, so it's not a classic, but it's surfable. The afternoon picks up a bit, with the swell building to 5ft from the west, and the wind still offshore from the SSE. The energy jumps to 191 (moderate), and it'll be clean. This is the best of a bad bunch, but it's really only for the beginners, as it's on the smaller side and a bit short-period.
The 22nd of August looks a bit bigger with 6ft from the WNW, but the wind is junk, switching to a cross and cross-onshore, making it choppy and messy. Not worth getting excited about.
So, the standout in this entire 16-day window is the afternoon of Friday the 21st of August at Harlyn. It's the only time the wind is clean and offshore, and the swell is big enough to ride. The break is south-facing, so it's a bit sheltered for the west swell, which is fine, but it's also listed as inconsistent, so you'll be waiting for the sets. Expect crowds there, as it's often busy. For the rest of the run, the beach setup with the onshore winds and choppy conditions looks more interesting for the kite surfers than for us paddle folk.
Rusty, signing off.

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.
