The Lowdown

Right, folks, Rusty here. Let’s have a look at what’s on the cards for the Harlyn stretch.

Honestly, it’s a pretty bleak start. We’re looking at a long stretch of flat, messy conditions that aren’t worth paddling out for. The first week is basically a write-off. From Sunday the 23rd right through to the end of the month, the swell is tiny, the wind is a nightmare, or both. The combined wave energy is barely a whisper, sitting at just 43 (weak) on the Sunday morning, and it doesn't get much better. There’s a brief moment on the 27th where the swell bumps up to 3ft from the SSW, with a bit of offshore wind, but it’s stormy and the energy is still weak at 144. Not one to get excited about.

The real gap here is a long one. We’re looking at a solid week of nothing until we finally get a glimmer of hope towards the end of the forecast.

The only window that’s got my heart beating a little faster is the morning of Friday the 4th of September. The swell is a consistent 5ft out of the west, with a period of 9 seconds. That’s a solid, workable groundswell. The wind is light offshore from the south, which should keep the surface glassy and clean. The combined energy reads a healthy 423 (moderate), and the forecast says “expect good surf conditions”. This is the one to keep an eye on.

Now, the morning of Sunday the 6th of September is a different beast. The swell is a beefy 8ft from the west, with a 9-second period, and the combined energy is a massive 1027 (strong). The wind is offshore from the SSW. This is going to be a powerful, draining wave. For experienced surfers only – that’s getting into the big stuff, and it’ll be a serious paddle. Beginners, stay well clear.

The water temperature is about average for this time of year, so nothing unusual to report there.

Alright, that’s the read. The waiting game is on for that Friday morning session. Keep your eyes on the forecast.

Rusty.

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.
