The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for us.
The next week and a half is a bit of a mixed bag, but there’s a real standout session hiding in there if you’re patient. The overall pattern starts with some solid, but messy, swell, then drops off into a long, quiet spell before a cleaner pulse of energy returns.
We kick off the forecast period on Sunday, September 6th. The afternoon is a write-off – a risk of thunderstorms, a moderate breeze blowing cross-off at 25 km/h, and the swell is a messy 1 m at 12 seconds from the SSW. It’s just not worth suiting up for. The combined energy is moderate at 847, but the conditions are marginal.
Things improve a little on Monday, September 7th. The morning brings a clean 1.0 m SSW swell, but the real gem is the Monday afternoon. The swell jumps to 2 m from the SSW, with a period of 12 seconds, and the wind is offshore from the ESE at 25 km/h. The wave comment calls it “excellent surf conditions for experienced surfers,” and with a solid 2 m and offshore wind, that’s the truth. The combined energy is strong at 1446. This is the best session on offer. Tunnels will be handling this swell beautifully with that offshore wind grooming it. Be aware, crowds are often here, so expect company.
Tuesday the 8th is a step down. The morning sees a 3 m SW swell with a short 10-second period and a strong 35 km/h cross-off wind from the S. That’s too big and junky for most, and the combined energy is a massive 1974, but the quality is poor. The afternoon drops to 2 m, but the period drops to 8 seconds – short-period, wind-affected slop. Skip it.
From Wednesday, September 9th, through to the following Saturday, September 12th, we hit a lull. Swell heights drop to 1.0 m or less, and while the winds are light and occasionally glassy (like Saturday morning with 0.7 m and glassy conditions), the wave energy is weak. The combined energy values fall to between 100 and 400, just not enough grunt for a proper wave. It’s a long, quiet stretch.
The next real hope comes on Saturday, September 19th. The Saturday morning shows a clean 1.0 m SSW swell with a 15-second period and a light 10 km/h cross-off breeze from the south. The combined energy is a solid 612, and the wave comment says “expect very good surf conditions.” This is a long-period groundswell, so it’ll be a bit more lined up and powerful, but at a point break like Tunnels, that’s a good thing. It’s a promising long-range call, but keep an eye on it as it gets closer.
The following Sunday and Monday (September 20th and 21st) look to fade back to messy, small, cross-on conditions. Nothing to get excited about.
So, if you’re keen, your window is Monday afternoon, September 7th for the best of the size and clean conditions. Otherwise, hold out for the morning of Saturday, September 19th for a cleaner, longer-period pulse.
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.
