The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the region. Straight up, I gotta be honest with you: this isn’t one of those periods where you’re rushing to get your board. We’re looking at a long, drawn-out stretch of small, marginal surf. The wind is a constant frustration – it’s cross-off from the ENE for the entire 16-day outlook, and it’s almost always blowing fresh to strong, which is going to put a bump on the face of anything that’s out there.
The forecast kicks off on Thursday, the 13th of August. Tunnels is showing some swell, but it’s a tough sell. The morning has a 4ft swell from the S, period of 16 seconds – so a proper, long period groundswell. Combined energy is moderate (766). That slow, powerful straight south swell is better suited to a point or reef, and with a strong cross-off wind from the ENE at 19 mph, it’s just not going to look good. By afternoon the sizes are up to 4ft, but the wind picks up to 22 mph, and the wave state goes poor.
Friday the 14th is more of the same: 4ft from the S in the morning, dropping to 3ft by afternoon, still locked into that cross-off breeze at 22 mph. The only standouts I’d even whisper about are the mornings way out in the second week – Friday the 21st, Saturday the 22nd, and Wednesday the 26th of August. These have the wave state marked as clean, but the quality is still just marginal. On the 21st, we’ve got a 2ft swell from the SW with a 17-second period, and the wind drops back to a light breeze at 9 mph. The combined energy is weak to moderate (316). It’s the best looking session on the list, but that’s not saying much. The 22nd is similar, and the 26th has a slightly bigger 3ft swell from SSW, with a 14-second period and moderate energy (547), but the wind is back to a fresh breeze by then.
Honestly, there are no true standouts here. Usually for a spot that’s fairly consistent, things pick up again, but this run of ENE cross-off wind is relentless. The setup here is more interesting for kite surfing than paddle surfing with these conditions. I wouldn’t bother paddling out unless you’re desperate for a foam board session or you see that wind swing onshore.
Rusty out.

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.
