The Lowdown
Alright mate, let’s have a look at what’s coming down the pipe.
It’s a pretty quiet start, to be honest. Not much happening at all for the first week and a half. A few days with some bumpy lines, but nothing you’d want to waste a session on.
We’ve got a dry patch that runs right up until nearly the end of the month. The only thing that really gets a mention before then is a Friday the 18th of September afternoon at Harlyn (Cornwall) where the combined energy is moderate (1014), but it’s still a “marginal” call.
The big one, and the one you should circle on your calendar, is Sunday the 27th of September at Harlyn. That afternoon is the real deal. You’ve got a 10ft swell coming from the West with about an 11-second gap, and the wind is going to be light and cross-off, so it’ll be clean. The energy reading is a huge 2360, so that's some serious power. That’s a big wave, over 8ft, so it’s a real expert-only affair. It’s a sheltered spot that doesn’t fire often, so when it does, it’s a proper treat.
The morning after, Monday the 28th, will be a nice comedown – 4ft with an 8-second period and glassy conditions. A good option for someone looking for something a little less heavy.

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.
