The Lowdown
Alright, grab a seat. Rusty here. Tunnels is what we’ve got on the table for this outlook, and it’s a bit of a strange ride ahead. The water’s sitting at a warm 81°, about 0.9° warmer than average for this time of year, so that’s a nice touch for the skin.
Right now, it’s looking pretty flat to start. There’s some swell showing, but not enough to get excited about. We kick off with waves around 2ft on Saturday the 12th, but it’s a cross-off breeze and the combined energy is only in the moderate range (245). It’s marginal at best, and honestly, the conditions aren’t lining up for a proper session. That vibe carries through Sunday and Monday with tiny, weak swells and energy dropping off.
The real story here is the wait for something half-decent. The standout moment, and I mean the *only* true standout across the whole 16 days, shapes up on Friday the 18th. The afternoon session especially is the jewel in the crown. Swell bumps up just a touch, but the big win is the wind finally turning offshore. We’re looking at a 3ft SSW groundswell with a very long period of 17 seconds, packing a strong energy level (617). That combo of clean offshore wind and that long-period juice will see Tunnels turn on. It’ll be lined up, groomed, and offering some proper rides. But here’s the thing with Tunnels—being an exposed reef, those big periods can make the wave a bit too straight, but with proper direction, it’ll be a gem. Just know it can get crowded – it’s “often” busy.
After that high point, the surf settles back into a marginal or poor groove for the rest of the second week. There’s a flash of another offshore moment on Thursday the 24th afternoon with a 2ft SW groundswell and moderate energy (285), but it’s not the same quality as the 18th.
Overall? We’re looking at a long, quiet start with a single, promising peak around Friday the 18th. If you can pick that window, you’ll be rewarded. The rest of the outlook is mostly small and choppy, so don’t hold your breath for consistent waves.
Rusty.

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.
