The Lowdown

Alright, surfers, let’s get into the 16-day picture for Tunnels. It’s a pretty lean run for a while, but we’ve got a little window of something to work with, and a longer-range spike that’s worth keeping an eye on.

The first solid stretch of surfable waves doesn’t really kick off until Wednesday the 26th of August. We’ve got a consistent cross-off breeze from the ENE blowing through most of the period, which is a good thing – it keeps the surface clean. But the energy is just weak for days. The combined swell energy is mostly in the low-to-mid hundreds, peaking around 408 (moderate energy) on the 26th morning, but the wave comment says “poor surf conditions” or “marginal” right through. The swell is small, around 2 ft to 4 ft, coming from the SSW or S. The period is long, between 14 and 18 seconds, which means it’s a groundswell, but it’s just not packing enough punch for Tunnels, which is exposed to the SW. That long period can also make a beach break a bit too straight, but Tunnels is a reef and point setup, so it’s a better fit. Still, the quality just isn’t there for a standout.

The real nod goes to the 8th of September, Tuesday. That’s our standout. We’re looking at 5 ft to 5 ft of swell from the S, with a period of 12 seconds. That’s a solid, moderate groundswell, and the combined energy jumps to 1143 and 1250 – that’s strong wave energy. The wind is cross-off from the S, which is just about ideal for this spot, keeping it glassy. The forecast is marked as “marginal” but scores a 2 out of 10, which is the best in the whole run. It’s a week and a half out, so it’s a promising call but not solid yet. That size is still good for intermediates, but it’s not huge. The water temperature is about average for the time of year. Just be aware that the 9th and 10th drop off fast with choppier conditions and a shorter period, so the 8th is the day to pencil in.

The rest of the 16 days? After the 8th, we’re back to small, low-energy surf and some rain and storm risk on the 7th, with onshore wind making it messy. The 9th and 10th have a bit more size but shorter period and a fresh to strong breeze, so it’s not going to be pretty.

So, bottom line: Wait for the 8th of September. That’s the best shot we’ve got. Otherwise, it’s a quiet spell.

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.
