The Lowdown
Alright, Rusty here. Let’s have a good look at what’s on the cards for Tunnels.
Straight up, this is going to be a tough stretch for anyone chasing waves. The first 16 days of August are nearly a write-off for quality surf. For the first week and a half, the swell is tiny—stuck around 1.3 ft to 2.3 ft—and the wind is locked in from the ENE, blowing cross-off. That sounds good in theory, but the wave comment calls it “poor surf conditions” for almost every session, with the energy sometimes weak (53) to moderate (366). It’s a frustrating run.
Things do finally start to move from Wednesday, August 12th onward. We’ve got a modest bump in swell height to around 3.3 ft to 3.6 ft, coming from the S with a period of 15 to 18 seconds. That’s a long-period groundswell, more energy behind it, and the combined energy jumps into the strong range (up to 865). The wind stays cross-off from the ENE, around 12 to 19 mph, which is a positive. Tunnels is exposed to swells and the optimum direction here is SW, so the S direction isn’t perfect, but with that length period it’ll wrap in. However, the forecasts still call it “marginal surf” with low scores. It’s not a standout, but it’s the closest we get to something rideable.
The very best bet, if you’re keen, is Wednesday morning, August 12th. Swell 3.3 ft from the S at 18 seconds, morning winds around 12 mph from the ENE, moderate energy (811). It’s not going to be pumping, but it’ll be the cleanest of a dirty bunch. That 18-second period means lines will have shape, but at a beach break like Tunnels, long-period S swells can sometimes straighten out.
Overall, the lack of quality options is noticeable. Crowds are likely at Tunnels if it does pick up. Water temperature is 80.2°, about average for this time of year.
Stay patient, mate.

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.
