The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for Harlyn. We’re smack in the middle of a long, quiet spell, and it’s going to be a bit of a patience game. The next week or so is looking pretty average at best, but there’s a glimmer of something solid if you’re willing to wait it out.
The immediate outlook is grim. The water is a touch warmer than usual for early September, sitting at 64°, but that’s about the only thing that’s comfortable. We’ve got a long stretch of poor surf with moderate to fresh breezes ruining the face of most waves. Swell energy is weak, barely hitting 69 for Sunday afternoon, and it’s just a messy, cross-off wind from the SW. Not worth wetting a wetsuit.
Monday the 7th sees a bump in size, but it’s a messy 7ft cross-on mess from the WNW with a long 13-second period. The energy is massive (1632), but the wind is straight on it, making it lumpy and choppy. That’s expert-only territory for the size, but the quality is shot. The rest of the week through to the 15th is a rinse-and-repeat of poor conditions, with cross-onshore winds and choppy sea states. The swell fades and picks up, but the wind never gives us a clean break.
Now, the real glimmer. Skip ahead to Thursday the 17th. This is the standout. Early morning, we’ve got a clean, 8ft swell from the west with a 10-second period, and the wind is a light, cross-off from the SSW. The energy is pumping (1250) and the conditions are forecast to be very good. This is the one to circle on your calendar. The break is famously inconsistent here, so when it lines up like this, you’ve got to move. It’s a beginner-friendly size, but with that long period, it’ll be bowling nicely on the point. Crowds are often a factor, so get there early.
After that, Friday the 18th morning holds a strong 8ft west swell with an offshore Southerly breeze, which is clean and good. The afternoon though, jumps to 12ft and gets a bit gnarly with a cross-off – that’s expert territory only. The following days drop off quickly into small, weak swells and messy winds, so don’t sleep on that Thursday the 17th.
Stay sharp, and don’t force it. The good one is coming.

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.
