The Lowdown

Right then, let's have a look at what's on the cards over the next couple of weeks. Honestly, it’s a bit of a flat spell we’re looking at for the most part. The energy is all from the south-west, but it’s running into a persistent cross-offshore breeze that’s just not letting things come together. We’re talking about Tunnels here, and for the first week and a half, it's a tough watch. The water temperature is sitting at a warm 81°, which is pretty much normal for this time of year, so at least it’s pleasant to be in the water even if you’re just floating around.

The first real chance of something rideable doesn’t pop up until that first day of September. Tuesday the 1st of September morning has a pulse of south swell at 3 ft with a long period of 18 seconds and a combined energy of 570 (moderate). That long period means it’s a proper groundswell with some grunt, but for a spot like Tunnels – a reef – that kind of period can make it a bit straight and fast. Still, it’s the best we’ve seen. The wind is a stiff cross-off from the ENE at 15 mph, which will keep it clean enough on the face. It’s a marginal call, but it’s where you’ll want to be.

Then on Wednesday the 2nd of September morning, we see a similar setup: 3 ft of south swell at 16 seconds, with energy at 496 (moderate). The wind drops right back to a gentler 9 mph cross-off, making the surface glassier. That’s probably the standout of the whole forecast period – light wind, clean lines, and a bit of push from the south. It’s not big, but for Tunnels, that’s a good morning out.

After that, the rest of the second week drifts back into that same marginal-to-poor pattern. There’s a bit of a bump around the 6th and 7th of September with the swell nudging up to 3-4 ft and energy climbing into the 600s and 670s (moderate), but the wind is back up to 19-22 mph from the ENE, and the comments are all “poor” or “marginal.” It’s just going to be choppy and hard work. No real standouts in that second week to get excited about.

So, the call is clear: if you’ve got a window, make it the morning of Wednesday the 2nd of September. The 3 ft of south swell with lighter winds will be the cleanest and most fun we’re likely to see. Tuesday the 1st morning is your back-up. The rest? Honestly, it’s mostly a waiting game.

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.
