The Lowdown
G'day, Rusty here, and I've been looking at the charts for our little corner of the world. To be honest, it's a bit of a tough stretch ahead. We're looking at Harlyn, which is a sheltered, beginner-friendly spot, and it's inconsistent. The water's sitting at 65°F, which is a touch warmer than normal for this time of year, so that's a small blessing.
We've got a long gap of nothing to get excited about from now through to the end of August. The first real chance of anything surfable comes around Thursday morning the 27th, but even then it's just "ordinary" conditions with a tiny 3ft swell from the SW. The wind is light and cross-off though, so it'll be clean. Still, the energy is weak (84), so it's not worth rushing out.
The outlook improves a little into the weekend. Friday morning the 28th is glassy with a 3ft SW swell, and the energy is picking up a bit (130). The swell period is short at 7 seconds, so it won't have much push, but those clean, glassy conditions make it a nice little option for a longboard or a foily. Saturday morning the 29th offers offshore winds and a 4ft W swell, but again, it's ordinary surf and the period is a short 6 seconds.
Come Sunday afternoon the 30th, we see a jump in energy to 240 and a 5ft WSW swell, but the wind is a strong 25 mph from the SW. It's clean, but that's a lot of wind for a small sheltered spot. Then Monday the 31st is a write-off – a massive 10ft W swell with a 10 second period, but it's accompanied by strong cross-shore winds and a messy chop. The energy is huge (2206), but the conditions are poor, and the swell is too big for the break.
The best option in the whole outlook looks like Thursday morning, September 3rd. We get a solid 5ft W swell with a 7-second period, and the wind is offshore from the SSW at 15 mph. The energy is moderate (305) and the conditions are clean. This is the one day where the setup all comes together for a decent paddle. It's still not a classic, but it's the standout.
We finish with a massive spike on Monday the 7th of September. There's a 15ft W swell with a very long 17-second period, and the energy is insane (10556). That's a huge, powerful groundswell, but the wind is cross-shore and the forecast says it's too big for the break. This is expert-only territory, and even then, the long period will make it break straight and fast at a beach break. This setup looks more interesting for kite surfing than paddle surfing.
So, in summary, keep your eyes on Thursday the 3rd of September for the best of a pretty average run. The rest is either tiny, windy, or just too big. Stay patient.
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.
