The Lowdown
Alright, Rusty here. Let’s talk about this stretch. We’ve got one spot in the mix, Tunnels. It’s a consistent, exposed reef that works best on a SW swell. Water temp is about average for this time of year, nothing to write home about.
The first week is a bummer. From Monday the 10th through the weekend of the 16th, the surf is just not there. We’re looking at tiny waves, 2ft to 4ft, with a short to moderate period, and cross-off winds that are too strong. The wave energy is weak to moderate. It’s all “poor” or “marginal.” Don’t even bother.
The one real standout, and it’s a weird one, is Monday the 17th morning. The models are showing a big pulse of short-period swell from the SSE hitting 10ft. That’s a lot of water for Tunnels – the notes say it’s predicted to be too big for this break. With a period of only 7 seconds, it’s going to be a chaotic, dumpy mess. This is only for the experts, and even then, it’s a gamble. The energy is moderate (839). The wind is cross-off from the S, which is onshore for this spot, so it’ll be messy. Honestly, this looks more like a kite-surfing session than a paddle.
After that spike, it drops back down. Monday afternoon through the rest of the second week, we’re back to marginal, small surf (1ft to 3ft) on a long-period SSW groundswell, but the wind stays a persistent cross-off, keeping it clean but gutless. The energy is weak. There’s a glimmer on Sunday the 23rd and Monday the 24th of August, with a bigger SSW swell: 3ft to 6ft, long period (18-22 seconds), and strong energy (up to 2179). This could be a promising long-range call. The long period is perfect for a reef like Tunnels, and the SSW direction is spot on. The wind is still cross-off, so it should be clean. This is a long way out, so treat it as a promising but uncertain late-season possibility.
For the best bet, circle that Sunday the 23rd and Monday the 24th of August. If that long-period SSW groundswell from the SW direction shows up, Tunnels could be firing. But the first week is a total write-off.
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.
