The Lowdown
Alright, Rusty here. Let's see what we've got.
It's a slow start, mates. The first few days are a total bust. From Sunday the 30th right through the end of the first week, it's flat and windy. The energy is weak, all readings under 400, and the wind is a solid 19-22 mph cross-off from the ENE. Not worth paddling out for.
Things start to turn a little in the second week. By Tuesday the 8th, the energy bumps up a bit, but it's still not clean. The real window opens up Wednesday the 9th of September. The wind dies completely, down to a 3 mph slight air. The swell is a small 3ft from the SSW with a 14-second period, and the energy is at 383. It's small, but it's glassy. Thursday the 10th is even better for wind, with a light breeze and a very long 18-second swell from the SSW. The energy is a little lower at 335, but that wind is the story. Tunnels is the only spot, and it's exposed, so that SSW groundswell will wrap in. It breaks fairly consistently, but crowds are a thing here, so get there early.
The standout is definitely Wednesday the 9th and Thursday the 10th. The swell is small, around 2ft to 3ft, but the wind is light to glassy, which is a massive win for clean waves. The 18-second period is a proper groundswell, so the waves will have shape and power, but that long period can make them wall up at a beach break. For a reef like Tunnels, it's a good thing. Thursday afternoon with that NNE 3 mph wind is basically perfect. The water temp is about average for this time of year.
After that, it fades again. The wind builds back up on the 11th and 12th, and the energy drops. By the 13th and 14th, it's back to very weak energy (under 35) and poor conditions. So, don't miss that mid-week window. It's not a big swell, but it's a clean one.

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.
