The Lowdown
Alright, let’s have a look at what’s coming up.
Honestly, it’s a pretty slow run for a while. We’ve got a gap of several days here where there’s just nothing doing. The first hint of something worthwhile doesn’t pop up until Thursday, August 27th, at Tunnels. The water temp is sitting at about 81°, which is pretty much normal for this time of year.
Thursday morning the 27th, we see a 4ft south swell rolling in with a solid 17-second period – that’s a nice groundswell. The combined energy is strong (1018), so there’s some decent power behind it. Wind is a cross-off from the ENE at 19 mph, which will keep things clean, but it’s a bit breezy. It’s only rated as marginal surf due to tide, so you’ll want to pick your moment. Afternoon drops off to 3ft and the energy backs off too (586). Still, Thursday morning is your best bet in that first week.
From Friday the 28th all the way through to Monday the 7th of September, it’s mostly poor conditions with small swell and that same fresh cross-off wind. A few spots show marginal surf on the 2nd and 3rd of September, but nothing to get excited about.
Now, keep an eye on Tuesday the 8th of September. That morning at Tunnels we’ve got a 3ft south-southwest swell with a 16-second period – another nice long-period groundswell. The combined energy is strong (552), and the wind drops right off to a light 6 mph cross-off. This is flagged as expecting very good surf conditions. That’s the standout in this whole outlook. Afternoon gets windier again, so get it early.
Then on Thursday the 10th of September, the wind goes glassy in the morning with a light easterly at 3 mph. Swell is only 2ft from the south-southwest, period 16 seconds, and energy moderate (299). It’ll be clean and fun on a longboard, but not big.
After that, Friday the 11th stays small and ordinary. So really, the one true standout to mark on your calendar is the morning of Tuesday the 8th of September at Tunnels. That’s your window.

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.
