The Lowdown
Alright, my friends, Rusty here. Let’s talk about what’s cooking.
The early part of September is a bit of a struggle for Tunnels. We’ve got waves coming in, but the wind is blowing cross-off from the ENE, which is no good for this place. The water is a warm 81°, right where it should be for the season.
Our first real sign of life comes Monday, September 7th. A S/SSW swell, about 3ft, rolling in with a long 17-second period. The wind swings light offshore from the ESE in the morning, and it’s going to be clean. The energy is solid (850), and it’s a proper groundswell. This is a good day for the intermediate crew.
But the big one, the one you’re circling on the calendar, is Tuesday, September 8th. The swell jumps to 6ft, coming from the SW at 14 seconds. The energy is massive (2090), and the wind is glassy offshore from the ESE in the morning. This is expert territory – too big for beginners, but for the experienced, it’s going to be a world-class day. The afternoon gets bigger (8ft), but the wind shifts, so get out early.
After that, things get quiet and messy from the 9th through the 13th. The energy drops off, and the wind stays on it. It’s a bit of a flat spell.
Then, on Monday, September 14th, a tiny but special swell shows up. Only 1ft, but the period is a staggering 24 seconds. That’s a very long period groundswell. The wind goes glassy in the afternoon, and the energy is moderate (273). It’s a perfect longboard day.
Tuesday, September 15th, is even better. 3ft at 21 seconds, with glassy conditions in the morning. The energy is strong (700). That morning session will be something else.
Tunnels does get crowded, and it’s fairly consistent, so be ready to share the peak. The standouts are the 7th, the morning of the 8th, and the morning of 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.
