The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’.

Alright, let’s be straight with you – we’ve got a bit of a flat spell to kick things off. The next week and a half is looking pretty average for Tunnels, but don’t you worry, the back half of this outlook is where we might finally see something worth paddling out for.

The main story is a long period, but tiny, SW groundswell hanging around. The issue is, for the first week, the energy is weak to moderate at best, with the combined energy mostly under 600 and often much less. The wind is a persistent cross-off from the ENE, which is okay for keeping the surface clean, but the swell heights are just too small – mostly 2 ft to 3 ft – to get the bank doing anything interesting. It’s a lot of time staring at a clean but gutless ocean.

Now, we start to see a bit of a pulse building around September 18. The Friday morning session shows combined energy hitting 632, which is moderate wave energy, with a 3 ft SSW swell and a period of 17 seconds. That’s a proper groundswell. But it’s still marginal, and the fresh breeze might make it a bit lumpy. Honestly, for a few days around the middle of the month, there’s hints of life but no real standout.

The real spark, the one you’ve been waiting for, shows up on September 27 – a Sunday morning. We’ve got a 2 ft SW groundswell with a 14-second period, combined energy of 241, and the wind drops right out to a light breeze from the ENE. That is clean, glassy potential, and the wave state says "expect good surf conditions". It’s not big, but for a spot that’s been starved, that’s the pick of the bunch. It’s an exposed SW reef, so this long period swell should wrap in nicely.

Then, to cap it all off, Monday September 28 morning brings another promising window. A 2 ft SSW groundswell with a very long 19-second period, combined energy of 474, and a light NE breeze. Again, the conditions are looking good. This is a groundswell with serious legs, and at Tunnels it should produce some clean, lined-up waves. Just remember, with that long period, the sets might be a bit spread out, but the paddling should be easier.

So, the bottom line: the first two weeks are a write-off for anything decent. But if you can hold out, the final Sunday and Monday of this forecast period are your best bets. It’s a classic case of waiting for the light at the end of the tunnel.

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.
