The Lowdown
Alright, Rusty here. Let’s break down what’s cooking at Tunnels. Honestly, the first week is a slow grind. There’s barely anything worth paddling out for until we get past the 13th.
The water’s at 81°, which is about normal for this time of year, so nothing unusual there.
Sunday the 13th is a total dud – 2 ft SW swell with a 15 second period, but combined energy is a weak 164. Just poor conditions all day.
Monday the 14th afternoon shows a little flicker: 2 ft from the SW with a super long 22 second period, combined energy climbs to 227 (moderate). Wind is cross-off from the NE at 12 mph, so it’s clean but still marginal. Not worth rushing for.
Tuesday the 15th is the best of the first week. Morning brings 2 ft SW swell at 20 seconds, combined energy at 392 (moderate). Cross-off wind from the ENE at 12 mph. Afternoon is similar: 2 ft, 19 seconds, energy up to 422. Still marginal, but it’s the most surfable window in the early run.
From Wednesday the 16th right through to Sunday the 27th, it’s a flat, windy mess. Swell runs 1 ft to 3 ft, periods mostly moderate to long, and combined energy sits in the moderate range – 200s to 500s. Winds are cross-off and fresh, 15-22 mph. These are poor surf conditions across the board. Save your energy.
One date to circle: Monday the 28th of September. That morning shows 3 ft from the SSW with a 17 second period and combined energy of 726 (strong). Wind is lighter, ENE at 12 mph, cross-off. It’s still listed as marginal, but that’s the biggest pulse of the whole outlook. It’s a long way out, but it’s got potential.
In short: Tuesday the 15th is your early small-wave option. The real standout is the morning of the 28th, but it’s a week and a half away. Keep an eye on it.
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.
