The Lowdown

Alright, grab a coffee, let me talk you through the Harlyn forecast. It’s been a bit of a sleepy start, I won’t lie. First few days are all small, weak energy.

Tuesday the 25th is a total dud. You’re looking at a 1ft to 2ft swell from the west-northwest, with combined energy in the double digits (60 to 88 – that's weak). The wind is light and cross-offshore, but there's just no juice. Don't bother.

Wednesday the 26th and Thursday the 27th are the same story – ankle-biters. Swell stays around 1ft to 2ft, period is a short 8 seconds, and the energy is pathetic (36 to 92). It’s clean in the mornings with a light offshore, but you’d be paddling for nothing.

Friday the 28th gives us a tiny pulse. The swell gets up to 3ft from the southwest in the morning, period is a terrible 7 seconds and energy is still low (98). That afternoon the wind swings and picks up, making it choppy. Still nothing.

Then things get ugly. Saturday the 29th throws a 7ft swell at us in the morning (combined energy 374 – moderate wave energy), but the wind is blowing hard out of the southwest at 19 mph. It’s clean-ish offshore, but that size with that wind is just a mess. By the afternoon, the swell jumps to 10ft and the energy spikes to 1204 (strong to very strong), but the wind is still a fresh breeze. It’s a proper beast, but too raw and unruly.

Sunday the 30th is the same – stormy and windy. Swell is 5ft to 7ft with a strong 25 mph wind. You’d be crazy to go out.

The first week is dead. There’s a big gap of poor conditions.

The one and only real standout is Wednesday morning, September 9th. That’s more than a week out, so pin a little salt on it, but right now it’s our best shot. The swell is a solid 8ft from the west-northwest (combined energy 915 – moderate to strong). The period is a short 8 seconds, so it’s windswell, not a clean groundswell. But the wind is light offshore from the south-southwest. That 8ft is big – experts only, beginners stay on the sand. The wind will keep it fairly clean, but the short period means it might be a bit lumpy and challenging. It’s the only time we see anything close to good surf.

The rest of the second week is lots of swell but poor conditions. Thursday the 3rd and Friday the 4th show 6ft to 8ft swells with strong cross-onshore winds making it a choppy, dangerous mess.

Look, Harlyn is a sheltered, inconsistent beginner spot. A run like this is just normal here. The water temp is about what you’d expect for this time of year. The whole sixteen days has very few windows. I’m only looking at the 9th, and even then, it’s going to be a battle. Bring a log you don’t mind dinging.

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.
