The Lowdown
Alright, let’s have a look at what’s on the cards for the next couple of weeks.
It’s a pretty quiet run ahead, I’m not gonna lie. There’s a fair stretch of nothing much here at Harlyn. The first week or so is mostly a write-off – you’ll see a lot of poor surf conditions with cross-shore winds and lumpy chop, and the swell is either too small or messy. It’s really not until the tail end of the month that we get a few windows that might be worth a paddle.
The first real standout comes on the morning of Saturday the 29th of August. It’s glassy as anything, with a calm wind and a little 3ft swell from the southwest. The combined energy is weak (119), but the conditions will be clean. It’s nothing special in size, but for a beginner-friendly spot like Harlyn, that’s actually a good thing. You’ll be able to get a few without any drama.
The next one to circle is Monday the 1st of September in the afternoon. The swell picks up to 6ft from the west-southwest, with a moderate offshore breeze, so it’ll be clean. The combined energy is moderate (283), and the wind is cross-off, so the face should hold up nicely. That’s a more interesting option for anyone who’s not a total beginner.
Now, there’s a bit of a spike on Tuesday the 25th of August – a 8ft swell from the west-southwest with a strong offshore wind, but it’s a bit much for most. That’s solid, and the energy is strong (845), but it’s on the edge of being too big for the average surfer here. The wind is cross-off, so it’ll be clean, but the swell is really only for the experienced crew.
The water temperature here is about 66°F, which is a touch warmer than normal for this time of year – nothing crazy, but you might notice you don’t need the thickest wetsuit.
If you’re looking at the middle of the week after that, there’s a couple of mornings with clean, glassy conditions on the 27th and 29th, but the swell is small. It’s more of a longboard or a grovelly shortboard kind of deal.
Overall, the best bet is Saturday the 29th of August for a glassy, chill session, and Monday the 1st of September if you want a bit more push. Don’t get your hopes up for the rest of it.

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.
