The Lowdown
Alright, Rusty here, looking at the next couple of weeks for us.
Honestly, it’s a slow start. There’s a big dry spell coming our way. The surf shows up on Tuesday August 11th, but it’s pretty miserable for almost a week and a half. You’ll be waiting until around the 22nd of August for anything that gets you excited. So yeah, a long gap of tiny, messy waves ahead.
For the first many days, the swell is small and the wind is a pain. A stiff cross-off breeze from the ENE is wrecking the little bit of energy we have. The combined energy is weak, sitting in the low hundreds at the start – nothing to get amped about. Waves are mostly under 3ft and the period is short, so no power. Water temp is about average for this time of year, nothing unusual.
Things start to look up on Saturday the 22nd of August. We see a small 2ft swell from the S, but with a super long period hitting 19 to 20 seconds. That’s real groundswell energy. The combined energy gets up to a moderate 531. The wind still blows cross-off from the ENE, so it’ll be clean. At Tunnels, that long S swell might be a little straight and fat, but after a week of nothing, it’s the first thing that’s worth a paddle. Expect some company, because it’s often crowded.
The real highlight, the one to plan for, is Sunday the 23rd to Tuesday the 25th of August. The swell builds to a consistent 3ft to 4ft from the S and SSW. The period stays good at 14 to 16 seconds, so the waves will have some shape and push. The combined energy is a solid moderate 857 to 886, so there’s some grunt. The wind holds as a clean ENE cross-off. It’s not a perfect pulse, but it’s the most consistent and surfable window in the whole 16-day forecast. At 3 to 4ft, it’s good for intermediates and fun for everyone.
After that, on the 26th, it starts to drop and the wind gets on it again. So, if you can, aim for that Sunday to Tuesday window at the end of August. That’s your shot.
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.
