The Lowdown
Hey, Rusty here. Let’s talk Tunnels for the next couple of weeks. Honestly, it’s a bit of a flat spell with a few flickers of life. The water’s about 80°F, which is pretty normal for the season, so you’re fine in boardshorts or a spring suit.
The first real chance comes on Sunday, August 16th, in the afternoon. We’ve got a 7ft swell from the SSE, but it’s short-period – only 8 seconds – with a fresh offshore wind from the SE that’ll keep the surface glassy. The combined energy is strong at 1044, so there’s some punch there. It’s a bit south of the preferred SW direction, but it’s the best wave of the run. Monday morning, August 17th, is also worth paddling out for – a gentle 15 km/h offshore from the E, with a 3ft S swell at 14 seconds. That’s a long-period groundswell, so better shape and easier paddling, with moderate energy at 389. Clean and tidy.
After that, it’s tiny. From the 18th through the 24th, we’re looking at 2–3ft swells, mostly from the SSW, with cross-off winds that are too strong for the size. The 22nd Saturday morning has a light breeze from the NE and a 2ft SW swell at 16 seconds, but it’s weak (355 energy). The 23rd to 25th picks up a little to 3ft, but it’s still marginal. The 25th Tuesday afternoon bumps to 4ft from the S, but with a fresh cross-off, it’s not clean.
The last week – from the 26th onward – stays small: 3–4ft S swells, moderate ENE winds, and energy around 600–760. Clean but weak. The 16th Sunday afternoon is the one for experts with that 7ft swell, and the 17th Monday morning is the best for intermediates. Everything else is a waiting game. Tunnels is fairly consistent, so it’ll turn around eventually, but this is a lean stretch.
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.
