The Lowdown
Hey, Rusty here. Look, I’ve pored over the numbers for this spot, and I hate to be the bearer of bad news, but the 16-day outlook is a total dud. Not one session that’s worth getting wet for. Swell comes and goes, but the wind and conditions just wreck it every time.
It all starts on Saturday, September 12th, with a 4-foot west swell rolling into Harlyn. The swell energy is low (214), the period is short at 8 seconds, so it’s gutless. The wind is a cross-off from the southwest at 15 mph, but the surf is just poor. It’s flat and uninspiring. Sunday the 13th looks a bit better – a 6-foot swell with a longer 10-second period giving moderate energy (574). But the cross-off wind is still messy, and the call is “marginal” at best. It’s not enough.
Come Monday the 14th, we’re back to 4-foot waves with short period, and moderate breezes making a mess. Tuesday the wind shifts onshore from the northwest, blowing 15 to 19 mph and stays onshore for days. Swell height bumps up to about 5 feet with moderate energy, but the conditions are “lumpy” and “choppy.” Honestly, with that much wind and bumpy faces, this is a better bet for kite-surfing than paddling. The waves have some push, but it’s a mess.
When the wind finally turns cross-off again on Saturday the 19th, the swell is 4 to 5 feet, but the period drops to 6 and 7 seconds. That’s short-period junk, with low energy – 183 and 302. It’s weak and won’t hold shape.
Then the real fade hits. From Monday, September 22nd, through Saturday the 27th, there’s a big gap of several days where the swell crashes below 2 feet. On Sunday, September 27th, there’s a spike of 6-foot swell from the WNW, but with a very short 6-second period under a fresh 19 mph southwest wind. That’s just a crumbly, messy wall of water – not for beginners, and not for anyone wanting clean waves.
Plain and simple: there’s nothing to chase here across the full 16 days. For this area, a run of bad surf does happen, and this is it. The charts could shift, but right now, leave the board at home.
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.
