The Lowdown
Alright, Rusty here, talking feet and miles an hour now.
First up, we’ve got Tunnels. Look, I’m not gonna sugarcoat it – the start of this run is a bit of a grind. From Monday, August 31st, right through the first week of September, the wind is just howling out of the ENE, a solid 18 to 25 mph cross-off. It’s clean, sure, but the swell is tiny and the energy is just not there. The combined energy is bouncing around in the mid to high hundreds – like 381 on Monday, dropping to 274 by Thursday – but the surf is just poor. It’s a frustrating wait.
The real talking point, and the only time this whole outlook gets my heart pumping, is Wednesday, September 9th. The wind finally drops right out, swinging around to the SSE at a gentle 9 mph, still cross-off. The swell direction is SSW, which is what Tunnels wants, and we’ve got a 3ft groundswell running on a 14-second period. That long period means the sets will have some real push and shape, and the energy is 316, which is a solid moderate. The conditions are labelled as “good” – that’s the one to circle on the calendar. That Wednesday morning and afternoon is the standout.
Beyond that, the energy fades again. September 10th and the following days see the swell drop back to 2ft or less, with the wind picking back up. The combined energy plummets to the low 100s and 200s. There’s a flicker of hope on September 15th, with a 2ft, 18-second SW groundswell and a gentle offshore from the ESE, but it’s a long way out and the energy is only 268. It’s promising, but treat it as a maybe.
So, for the keen ones: Wednesday, September 9th. Tunnels, SSW swell around 3ft, that long 14-second period, light wind, clean. That’s your window. The rest of the fortnight is mostly a write-off for a proper paddle.
Rusty.

Information about the Tunnels Surf forecast
The above surf forecast table for Tunnels provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tunnels can be found by selecting the local surf guide option on the grey menu. Our Tunnels 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 (Tunnels) 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 Tunnels 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.
