The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next sixteen days at Harlyn.
Honestly, it’s a bit of a slow burner. The first week and a half is mostly a write-off. From Monday the 31st of August right through to the end of the week, we’ve got a fair bit of swell rolling in, but the wind just has other ideas. That Monday morning kicks off with a solid 8ft swell from the W, carrying a big 10-second period, and the combined energy is pumping at 1352 – that’s proper strong energy. But it’s cross-on at 22 mph, and the report says it’s lumpy. That’s a no-go for a clean surf. A couple of mornings in early September, like Tuesday the 1st, the wind swings cross-off and it cleans up for small 4ft waves, but the energy is low (196) and it’s just ordinary. Wednesday the 2nd even has offshore wind on the morning with a 2ft swell, but it’s too weak and short-period to get excited about. The dead zone runs basically from now until the second weekend.
We finally see a glimmer of hope on Tuesday the 8th of September. The morning shows a clean 5ft swell with only a 3 mph breeze. The energy is moderate (362) and it’s surfable, but it is still just ‘very ordinary conditions’. That afternoon picks up to 6ft with moderate wind, but the energy jumps to 709 – a sign things might be shifting.
The real standout, the one worth marking on the calendar, is Monday the 14th and Tuesday the 15th of September. Monday morning lights up with a 8ft swell from the W, 9-second period, and the combined energy is a massive 1121. It’s clean with a moderate cross-off breeze. That afternoon bumps to 10ft (1396 energy) – that’s getting big, and the report calls the tide questionable, so you’ll want to be on your game. But the true gem is Tuesday the 15th. Offshore wind, 7ft of W swell with a lovely 11-second period, and combined energy of 1122. The report says “expect very good surf conditions.” That’s the call.
The water temp is sitting at 65°F, which is 4°F warmer than normal for this time of year – a touch warmer than average, so you might get away with a slightly thinner spring suit.
For the long-range, Tuesday the 15th is the best on offer. As it’s more than two weeks out, take it with a pinch of salt, but if it holds, that’s your day. For the rest of it, especially the first week, you’d be better off doing something else. This is a classic case of waiting for the clean window.
Rusty out.

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.
