The Lowdown
Alright, this is Rusty. Let's talk about what's on the menu for the next couple of weeks.
Alright, straight up, the next week or so is looking pretty grim for any decent paddle surfing. We’ve got a solid run of days where the conditions just aren't lining up. The energy is weak, and the wind is a constant problem. The only real standout in the whole 16-day window is a little glimmer of hope way out in the second week.
Right now, from Sunday the 9th right through to Monday the 17th, I’m seeing nothing but poor surf conditions. The wind is a persistent cross-off from the ENE at 15 to 22 mph, which is just too strong, and the swell is tiny – mostly below 2.6 ft. The combined energy is weak, mostly under 400, and it just doesn't have any punch. Don't even bother.
Now, we finally get a little change on Tuesday the 18th. The morning is looking glassy calm with the wind dropping to 0 mph. That’s a major positive. The swell is still small, only 2.3 ft from the south with a period of 13 seconds, but the combined energy is only 162 (weak). It's surfable, but "very ordinary" is the term used. It's a small, clean wave for the patient surfer, but it's not going to be a standout.
After Tuesday, the wind kicks back in and we're back to poor conditions for Wednesday and Thursday the 20th. The swell tries to build, but the wind is still an issue.
The best chance of a decent wave comes on Friday the 21st of August. The swell is picking up, with a mix of swells giving us a combined energy of 655 (moderate). The morning is marginal, but the afternoon sees a 3.9 ft swell from the SSE with a period of 11 seconds. The wind is still a cross-off from the ENE at 19 mph, which is a bit strong, but it's clean. It’s still a marginal call, but it’s the best we’ve got.
Looking further out, Saturday the 22nd of August has the biggest swell of the forecast, 5.2 ft from the south with a period of 10 seconds. The combined energy hits 783 (moderate). But that 10-second period isn't ideal, and the wind is still up. Again, it's a marginal forecast, but it's a bigger wave. This one is more promising but still uncertain.
So, for the best on offer, I'd say keep your eyes on the afternoon of Friday the 21st and maybe Saturday the 22nd of August. They aren't perfect, but they are the only windows where the energy is up and the conditions are not completely blown out. The rest of the time, it's a write-off.

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.
