The Lowdown
Alright, Rusty here. Let’s chew the fat on what’s gonna be happening in the water.
Honestly, it’s a pretty rough start. The first week is a real dud. There’s some southerly swell showing up, but it’s getting hammered by a strong easterly breeze, making everything choppy and ugly. The wave energy’s all over the place, from 360 (weak) to over 500 (moderate), but it just doesn’t matter when the wind’s that bad. You’re looking at a solid gap of almost a week before anything decent comes along.
The real gem shows up on Tuesday, September 8th. That morning at Tunnels, we’re looking at a 3ft swell from the SSW with a 15-second period – that’s pure groundswell, packing a punch with a moderate energy reading around 580. The wind is a light southerly cross-off, so it’s gonna be clean and lined up. Tunnels is exposed, so it’ll eat that swell up. The water’s sittin’ around 81°, which is pretty much normal for this time of year. Crowds are a regular thing here, so expect some company. That Tuesday morning is your absolute best bet – the standout of the whole run.
Then, on Tuesday afternoon, the wind just dies. Absolute glass. The swell drops a bit to 3ft, but it’s still that solid 14-second SSW groundswell. Glassy conditions at Tunnels are about as good as it gets – silky smooth faces. That’s your second best option in the whole 16 days.
After that, it gets iffy again. Wednesday the 9th has some 3ft WSW swell, but the fresh easterly wind comes back and makes it just marginal. Not worth the effort. The second week fades out into smaller, weaker swells with the energy dropping to just 133 (weak) by the 14th. There’s a tiny bump on Sunday the 13th morning with 2ft SSW groundswell and very light easterly winds, which would be clean, but it’s just small. Surfable, but nothin’ special.
So, put it this way: if you can get out on Tuesday, September 8th, especially the morning, that’s your session. The rest of the time, you might as well wax your board and wait.

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.
