The Lowdown
Alright folks, Rusty here. Let’s get straight into what’s happening for the next couple of weeks. We’ve only got one spot on the radar, so let’s keep it simple.
The whole 16-day window is a bit of a struggle, to be honest. For the first week, the surf is mostly poor, with a lot of messy cross-onshore winds and choppy conditions. There’s a big gap of several days where it’s really not worth getting wet. The energy picks up a bit, but the wind just ruins it. Things finally start to turn towards the end of the second week, but it’s a long wait.
Now, let’s talk about the standouts. The only real time to paddle out is on Monday, September 15th. The morning session at Harlyn is about as good as it gets. We’ve got clean offshore winds from the south at just 3 mph, which is a major positive. The swell is a modest 3 ft from the west, with a period of 11 seconds, giving it a bit of groundswell punch. The combined energy is moderate (188). It’s a beginner break, and it’s inconsistent, so don’t expect a wave every minute, but it’ll be clean and glassy. The water temp is about average for the time of year, so no need to worry about a wetsuit change.
Heading into the weekend of September 20th, it’s still a bit of a write-off. The onshore winds and small surf keep it poor. The only other flicker of hope is on Wednesday, September 24th. The morning shows a decent 3 ft swell from the west-northwest with a very long period of 13 seconds. That’s proper groundswell energy (522). The wind is cross-shore from the east, so it’ll be a bit bumpy, but the quality of the swell might make it worth a look. It’s a marginal call, and still inconsistent, so temper your expectations. After that, the energy drops hard, and we’re back to small, weak surf to finish the period.
So, to sum it up: the best bet is the morning of Monday, September 15th for some clean, small waves. The long-range swell on the 24th is promising but less certain. Don’t hold your breath for the rest.
Stay salty,
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.
