The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for the next couple of weeks.
It’s a bit of a slow burn to start. We’ve got some swell, but the wind is just ruining it for the first few days. The waves are there, but the conditions are no good, so you’ll be watching from the sand. Be patient, because the fun stuff is coming.
The real standout is going to be Sunday the 6th. The wind is set to swing offshore from the ESE, a gentle 9 mph, and that’s the key. We’ll see a solid 7ft SSW groundswell with a 13-second period, and the energy in the water is pumping at 1499. This is going to be excellent for experienced surfers. Tunnels will be packing, but the crowds are often there, so get in the water early to score the clean ones.
Monday the 7th is for the big-wave crew only. The swell is forecast to be huge, hitting 18ft from the SSW with a very long 15-second period. The energy is absolutely massive at 13145. The wind will be strong offshore, so it’ll look clean, but at that size, Tunnels is a strictly expert-only zone. The paddle out is going to be a serious battle.
After that, the swell drops right off. The 8th and 9th have some cleaner, smaller waves, but nothing special. The 14th of September, Monday, we get a glassy morning with a tiny 1ft swell from the SW, but it’s got a ridiculously long 25-second period. That’s an ultra-long period groundswell, so it might be a bit too straight for the beach, but if it connects...
Then we have a nice window through the 15th and 16th. The 15th of September, Tuesday morning, is looking good. Light offshore wind from the ESE at 6 mph, with a 3ft SSW groundswell carrying a 21-second period. The energy is moderate at 857, and the conditions look very good. It’s not a big swell, but with that period, it’ll have plenty of punch. The wind holds through the morning, so that’s your best bet for a clean, fun session in the second week.
After that, it fades into small, weak waves. Water temp is sitting around 81°, which is pretty average for this time of year, so you’ll be fine in boardshorts or a spring suit.
That’s the whole picture. Score that Sunday session, and keep an eye on the 15th.
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.
