The Lowdown
Alright, let’s have a look at what’s on the table.
Alright, let’s be straight with each other. We’ve got one break on the radar: Tunnels. It’s exposed to the swell, and it catches a bit of a pulse early next week. The opening day, Monday the 7th of September, sees a solid push – morning starts with a clean, fresh offshore breeze from the east at 19 mph, and a 3ft SSW swell with a very long period of 17 seconds. That long period means proper groundswell energy, and with that offshore wind, Tunnels will be clean and lined up. The combined energy is 1059 (moderate). It’s a fairly consistent spot, so you can expect sets. The water temp is 81°, pretty much average for this time of year, so no surprises there. Crowds are likely though – Tunnels often has company in the water.
By Monday afternoon, the swell jumps to 7ft from the SW, period drops a notch to 14 seconds, but the offshore wind holds from the ESE at 19 mph. That’s proper, meaty surf. Still clean, still punchy. This is the standout of the whole outlook.
Now, Tuesday the 8th sees the swell hanging in at 7ft from the SSW in the morning, but the wind swings to a southerly cross-off at 22 mph, which will mess with the face a bit. Still clean-ish, but not as good as Monday. The period drops to 9 seconds – short period windswell mixing in. Afternoon drops to 6ft but with an 8-second period – not as inviting.
From Wednesday the 9th onward, the swell fades and the winds go cross-off or cross-shore, with only small waist-high waves around 3ft and long periods returning, but weak energy. The combined energy drops into the 300s – weak. From Thursday the 10th right through to the 22nd of September, it’s a long stretch of tiny, weak surf. Most days have poor surf conditions, with cross-off winds and swells between 1ft and 3ft. The combined energy hangs mostly in the low hundreds to around 500 – weak to very weak. Not worth paddling out for.
So, the best on offer is clear: Monday the 7th of September at Tunnels, especially the morning session with that long-period groundswell and offshore wind. The afternoon is also quality but bigger. After that, it’s a dry spell for over a week and a half. Still, Monday is a cracker.

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.
