The Lowdown
Alright folks, Rusty here. Let's have a proper look at what Harlyn's got cookin' over the next couple of weeks.
Right off the bat, look, the outlook's a bit of a slow burner. There's nothing really happening right now. The next week is mostly full of poor surf conditions, cross-offshore and onshore winds, and messy wave energy. The water temp is about average for this time of year, so no surprises there.
The best chance of a decent wave comes later on the morning of Saturday, September 5th. We've got a tiny window of glassy, clear skies. Swell is a very clean 4ft from the West with a moderate 10-second period, giving us moderate wave energy. For a break that's rated for beginners and can be inconsistent, that's about as good as it gets in this window. The crowd situation isn't mentioned, but since it's a rare clean day, expect some company.
After that, things turn average again. The following Tuesday afternoon, the 8th, a bigger 8ft West swell pushes in with strong energy, but it's cross-offshore wind and the conditions are described as only marginal. Wednesday the 9th brings a strong 25 mph offshore wind, making it clean but a real battle to paddle into that 8ft groundswell. That's expert territory.
Looking into the second week, there are a couple of mornings with small, surfable bump, but nothing special. The 14th and 15th see more long-period (12s) West swells, but they'll be blown out by cross or onshore winds, creating choppy conditions. A long-period groundswell like that would be better on a point or reef, but at a beach break like Harlyn, it's going to just close out in the onshore junk. It's just not our time.
Overall, mark your calendar for the morning of the 5th. That's your one true standout. Everything else is a write-off or a marginal gamble.
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.
