The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Harlyn over the next couple of weeks.
Right, I’ll be straight with you – the outlook for Harlyn is a bit of a mixed bag and there’s a fair bit of waiting involved. The next week or so is pretty grim for proper surfing, with a lot of windy, lumpy conditions muscling in. The water temp is sitting at 64°, which feels a touch warmer than normal for the time of year.
There’s a real gap in quality action here. The first real glimmer of something decent doesn’t show up until Monday the 7th of September. That morning, we see a jump in swell to 7ft from the West, with a long period of 13 seconds – proper groundswell energy. The combined swell energy is moderate (1465). The wind is cross-shore and a bit messy in the morning, but the afternoon cleans right up with a classic cross-offshore breeze. That Monday afternoon session, with a 7ft West swell and 12-second period, is easily the standout of the whole forecast. The waves will have some real push and shape, and with clean conditions, it’s the pick of the bunch for sure. Keep in mind though, that 7ft plus is more for the experienced crew.
After that, the wind turns nasty again, with strong onshore flows making a mess of things mid-week. There is another pulse of bigger swell on Tuesday the 15th of September, with 8ft to 8ft from the West, but it’s accompanied by a fresh cross-shore wind that’s going to leave the surface lumpy and cross-chop. Not worth getting excited about.
Beyond that, the second week sees the swell drop right off, and we’re left with smaller, weaker energy and mostly average winds. Nothing really stands out as a must-surf session in that later period.
The Best Bet: Your best chance at something memorable is Monday afternoon, September 7th. Get on the 7ft West swell with that cross-offshore wind. It’s the only time the stars really align for a clean, quality wave.
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.
