The Lowdown

Alright, let’s talk Tunnels. This spot picks up SW groundswell pretty well, but for most of this forecast it’s shaping up to be a tough go. Water temp is about 81°, right around normal for this time of year, so nothing wild there.

The first real chance to get wet comes on Tuesday, September 1st. It’s only marginal, really. The swell is tiny, about 3ft from the SSW, with a period of 18 seconds – that’s proper long-period groundswell. Combined energy reads 505, which is moderate, but that long swell is going to make it fat and straight at a beach break like Tunnels. The wind is a fresh cross-offshore from the ENE at about 19 mph, so the surface will be clean, but you’re going to be scratching hard for any kind of ride.

The next slightly better window lands on Tuesday, September 8th. The morning shows 3ft from the SSW, period 16 seconds, and the combined energy hits 567 – that’s the highest energy of the whole run, still in the moderate range. Wind is ENE again at 16 mph, cross-off, keeping it clean. You’re still looking at marginal, tide-dependent waves, but if you’ve got a log, there might be a few fun little lines.

Now, Saturday, September 12th brings a bright spot. Early morning, the wind goes glassy, completely calm. The swell is only 2ft from the west, period 14 seconds, combined energy a weak 203. But the glassy conditions make it the best of the bunch for just getting out and enjoying a clean, small session. The afternoon stays clean with a light cross-off from the NNE at 6 mph. This is the standout – not for power, but for a peaceful, clean paddle. If you’re a beginner, nothing in the whole 16 days gets above 4ft safe, so you’re fine on that front.

The crowds at Tunnels can be a factor, and with the surf being this inconsistent, it might feel crowded for what’s on offer. There’s a big gap of mostly poor days to start, so don’t rush. Best bet is that glassy Saturday morning on the 12th – small and tidy, a surfer’s quiet moment.

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.
