The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’.
Honestly, it’s a pretty quiet stretch ahead for Tunnels. For the next week and a half, the surf is small and the wind is mostly a stiff cross-off shore breeze, which keeps things clean but doesn’t help the tiny waves. We’re looking at a long run of marginal to poor conditions until we get towards the tail end of the window.
The first real glimmer comes on Thursday, the 24th of September. That afternoon, the wind drops right back to a light breeze from the SSE, going cross-off, and we finally see a clean-up. The swell is a modest 2 ft from the SSW, with a long 18-second period – that’s proper groundswell energy. The combined energy reading hits 406 (moderate), and for a reef like Tunnels, that long-period SSW swell will wrap in nicely, offering some proper shaped lines. This is the standout of the whole outlook. The water temperature is sitting at 81°, about normal for this time of year. Just keep in mind Tunnels is a fairly consistent spot, but it often draws a crowd, and this is the best day by a long shot, so you won’t be alone.
Before that day, it’s slim pickings. Friday the 18th of September afternoon shows a 3 ft SSW swell with a 17-second period and moderate cross-off breeze – a marginal option, combined energy at 673 (moderate to strong), but it’s still not the quality we’re waiting for.
After the 24th, the wind picks up again on the 25th and 26th, and the surf drops back off. So really, that Thursday the 24th is your target. Mark it.
Stay patient.
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.
