The Lowdown

Alright, let me have a look at what we’ve got for the next 16 days. It’s not a classic start, I’ll tell you that much. The first few days are a real write-off, with a stormy setup and strong winds that just won’t let up. The water temperature here is sitting at 66°, which is a touch warmer than you’d expect for late August, so that’s something.

We’ve got a long gap of poor conditions until we finally see something worthwhile. The standout window is towards the end of the second week.

From the 29th of August right through until the 6th of September, it’s a mess. Strong winds, lumpy cross-shore chop, and the swell energy is all over the place, with combined energy readings mostly in the hundreds (248 to 1263), but the quality is just not there. The wind is either cross or cross-off, and it’s too strong to enjoy. The 1st of September Tuesday morning has a cleaner look with a 4 ft WSW swell, but the energy is weak (196) and it’s pretty small. Not worth paddling out for.

The 7th of September Monday morning is the first real glimmer. We’ve got a 6 ft swell from the west with a period of 11 seconds, and the wind is light from the ESE, almost glassy. The combined energy is strong (889) but the wind is offshore, so it’ll be clean. That’s a very good window for a wave. But the afternoon turns nasty with a strong onshore, so you’ll want to be out early.

The real standout, and the one I’d circle on the calendar, is the 11th of September Friday. That morning we’ve got a 7 ft west swell with a very long period of 14 seconds, and the wind is light from the south, offshore. The combined energy is massive (1744), and it’s clean. That’s a proper groundswell, and with that long period, it’s going to be a better fit for a point or reef setup, but even at Harlyn, if the sandbanks are behaving, it’ll be a ripper. The afternoon holds up with a 7 ft swell and 12-second period, still offshore and clean. That’s the best on offer, no question.

The 10th of September Thursday afternoon is also worth a mention – an 8 ft west swell with offshore wind, good energy (1207), but it’s a bit bigger, so more for the experienced crew.

The 12th and 13th of September are still solid, with 5 ft to 6 ft west swells, clean conditions, and moderate energy, but they won’t match the punch of the 11th.

So, to sum it up: you’ve got a long, frustrating wait, but the 11th of September is the day to be in the water. Early morning, glassy, and a solid groundswell from the west. That’s the one.

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.
