The Lowdown
Alright folks, Rusty here. Let’s get straight into it. This forecast window for Harlyn is a long, hard wait for very little reward. We’re looking at over a week of pretty ordinary conditions before anything even remotely surfable shows up. The first solid recommendation doesn’t appear until the 14th of September, so get ready for a long stretch of checking the cams and finding nothing but wind.
The first real chance of a wave doesn’t come until Monday the 14th. We’ve got a 4ft swell rolling in from the west with a solid 12-second period, giving it a nice long groundswell feel. The combined energy will be moderate (411). The game-changer is the wind. Monday morning sees a light SSE offshore breeze, and by the afternoon it goes glassy. That’s a major positive – clean, peeling faces. The water temperature is 65°, which is a touch warmer than normal for this time of year, so the thick wetsuit might not be needed.
Tuesday the 15th still has some life in it. The swell drops slightly to 3ft but the period is still a good 11 seconds. The morning is clean with a light cross-offshore breeze from the SSE. The energy is moderate (231) and it should be surfable, but it’s a definite step down from the Monday session.
If you’re an expert, the Monday the 8th might have caught your eye. There’s a 8ft swell from the west, but it’s a short period at 9 seconds, and while the wind is cross-offshore, the conditions are flagged as marginal. The energy is high (893), but that short period means it’ll be a lumpy, chunky mess at this beach-and-reef setup. Honestly, with that much wind, it looks more interesting for the kite surfers than for paddle surfing.
The 14th of September is the standout. Glassy conditions, a solid 4ft west swell, and a long period. That’s your window. It’s a rare moment of quality in this forecast, so don’t sleep on it. As for crowds, Harlyn is often busy, so get there early for that Monday morning glass-off.
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.
