The Lowdown
Alright, folks, let's talk about the next couple of weeks down at Harlyn. It’s a bit of a mixed bag, a tale of two halves really, so let’s get into it.
To start things off, the water is sitting around 64°, which is a touch warmer than we’d usually expect for this time in September. It’s a nice little bonus, but don’t get too comfortable because the surf is going to be the main story.
The first week is going to be a real test of patience. We’ve got a run of days where there’s surf on offer, but it’s messy. From Friday the 11th right through to the 16th, we’re looking at cross-onshore winds and lumpy conditions. It’s not what you’d call quality. The swell is there, around 4ft to 6ft, but it’s just not organized. The energy is moderate, with readings in the 200 to 300 range mostly.
Then we hit a rough patch. From the 17th through to the 23rd, things get properly poor for surfing. The wind is either strong and cross-shore or onshore, making it choppy and messy. There is a day with a bit of a bump on the 17th, with swell hitting 6ft, but it’s coming with a short 7-second period and a strong breeze, so it’s just going to be a washing machine. We also see a couple of smaller days on the 20th and 23rd, where the swell drops right down. The 23rd is clean but tiny, around 2ft, not even worth getting the board wet for. It’s a full week of blown-out or non-existent waves.
But hang on. The light at the end of the tunnel is Thursday the 24th. The wind switches offshore, and things start to clean up. We have a rising swell, up to 6ft, and the energy starts building in a big way, getting up to 1055. But the standout is really Friday the 25th of September. The wind will be offshore and light, and the swell will be a solid 6ft from the WNW. This is the day. It’s a proper groundswell with a 12-second period, and the energy is a solid 905. This is the one to circle on the calendar. It’s a couple of weeks out, so don't take it as gospel just yet, but it’s looking like the best chance we’ll get. Harlyn can get a bit fat and straight on a long-period swell, but with that wind, it’s going to be the pick of the fortnight.
So, to sum it up, the next week and a half is a write-off, but there’s a real gem waiting for us at the end of it. Dust off the log for that Friday session.

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.
