The Lowdown
Right then, let’s be straight with you. Harlyn’s a sheltered little cove, and it’s a beginner’s spot, but it’s inconsistent. Water temp’s sittin’ at 65°, which is a touch warmer than normal for this time of year – feels nice on the skin. The problem is, for the entire 16-day window, there’s not a single session I’d call a good one. The combined swell energy maxes out at a weak 99 (just 99) on the Monday morning of the 3rd, and every other block of the forecast is a write-off.
We kick off Monday morning, August 3rd, with a tiny 3ft swell from the WSW, period at 9 seconds and a light SSE breeze. It’s clean, but the energy is weak (99) and the surf is just very ordinary. That afternoon goes glassy but the swell drops to 2ft. Tuesday the 4th sees a bit more size, 3ft, but the period drops to short 7 seconds and the wind is howlin’ from the SW at 15 mph, then 18 mph – it’s messy. Wednesday the 5th brings a bigger pulse of 7ft from the W (combined energy 453), but it’s cross-shore wind at 18 mph, creating lumpy, cross-choppy slop. That’s too big for beginners and too ugly for anyone else.
Thursday the 6th is cross-onshore and choppy, with 5ft and a short 6-second period. Friday the 7th and Saturday the 8th are flat, with swell barely hitting 1.0ft. Sunday the 9th has a brief moment of glassy conditions with a 2ft swell, but the period is a short 7 seconds and it’s tiny. From there, it’s a long stretch of tiny, wind-affected, or onshore slop all the way through to the end of the 16 days. The combined energy values are almost all in the two-digit weak range.
There’s a tiny spike on Sunday the 16th of August, with a 5ft swell from the N, but the wind is cross-onshore at 12 mph, so it’s just choppy again. There’s no standout session here. For a sheltered spot like Harlyn, it’s a real bummer. The setup with that significant swell and cross-shore wind on the 5th looks more interesting for kite surfing than paddle surfing. It tends not to stay poor for long, but this run is a blank one.

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.
