The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for the Tunnels area. It’s a bit of a slow burn coming up, with plenty of time to wax your board and check your fins.
We’ve got a run of pretty ordinary conditions kicking off this outlook period. Starting Thursday the 27th of August, there’s some small swell around 3 ft coming from the south, but that fresh 30 km/h cross-off breeze from the ENE is really just making it a messy affair. The combined wave energy is moderate at best (561), but the quality just isn’t there. Friday the 28th through to the end of August is rough – same small south swell, same fresh wind. The water temperature is about average for the time of year at 81°, nothing special there.
The first week of September doesn’t offer much to get excited about either. We’re stuck in a pattern of marginal to poor surf conditions from the 1st to the 6th. The swell stays small, mostly under 3 ft from the S or SSW, with that persistent ENE wind keeping things choppy. There’s a couple of days (1st and 6th) where the energy picks up a bit (around 441 to 548), but the wind kills it. This is a long, quiet stretch of about 10 days.
Now, here’s the one that has my heart rate up. Mark your calendars for Monday the 7th of September. This is the standout in the whole 16-day window. The Tunnels are looking at a clean 4 to 4 ft of SSW groundswell with a solid 15-second period. That’s proper energy, and with a combined swell energy of 631, it’s got some push. The best part? The wind goes light, shifting to a gentle offshore from the east on Monday afternoon. That is going to groom those lines beautifully. The offshore wind and the long period swell from the SSW hitting this exposed reef setup is the recipe for a really good session. It’s an intermediate wave, so it won’t be for total beginners, and since crowds are “often,” expect some company for these clean waves.
After that little taste of glory, the 8th and 9th of September see the energy drop back off and that fresh cross-off wind returns, so it’s back to the ordinary stuff. The end of the forecast window around the 10th and 11th of September is a complete dud. Swell is tiny, wind is all wrong, and the energy is weak.
So, the call is clear: sit tight, watch the wind, and be ready for that Monday the 7th. That’s the day.

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.
