The Lowdown
Alright folks, it’s Rusty here with a look at Tunnels over the next couple of weeks. Gotta be straight with you – this forecast is a slow burner. We’ve got a lot of days where the swell is just too small and the wind is a bit messy, so we’re looking at a long wait for the quality windows.
The water is sitting at a warm 81°, which is pretty much what you’d expect for this time of year, so no need for a thick suit.
The pick of the entire 16-day period is going to be the morning of Sunday, August 16th. We’ll see a jump in energy with a solid 7ft swell from the SSE, pushing the energy rating up into strong territory (1146). It’s a short-period swell at 8 seconds, which means it’ll be a bit crumbly and might close out, but the wind is howling offshore from the SE at 19 mph. That’s going to groom it up nicely, keeping the surface glassy and clean for those with the skills to handle the size.
After that, the windows get smaller. The afternoon of Friday, August 21st, into Saturday morning, August 22nd, offers the next best chance. The swell drops way back to 2ft from the SW, but the period stretches out to 16 seconds – proper groundswell that will wrap nicely into Tunnels. The wind will be light and even glassy on the Saturday morning with almost no breeze, so expect silky conditions for longboard or a fun mid-length.
Be aware, Tunnels can get crowded, so get in early for those cleaner sessions. After the August 16th peak, the energy fades and we’re mostly looking at minimal swell and cross-off breezes from the ENE, keeping things small and weak right through until the middle of the second week.
There is a glimmer of hope again as we head into Wednesday, August 26th, with a 2ft swell from the S carrying a very long 19-second period. The energy is moderate (702), but the wind is still a cross-off from the ENE at 19 mph, which is a bit of a chop magnet. The 27th of August also looks similar, but nothing truly stands out as a ‘must-surf’ day. It’s all a bit marginal, so keep an eye on the wind, because if it backs off, those long-period groundswells could be fun on the peak.
— 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.
