The Lowdown
Alright, let’s get into it. We’re looking at Tunnels, a spot that faces a bit of a challenge for the next couple of weeks. The water temp is running about average for this time of year – nothing to write home about, just standard.
The first half of this forecast is a bit of a grind. For the next week or so, from Tuesday the 25th right through to the end of August, the swell is just too small and the wind is decent but the energy is weak. Expect a lot of poor surf conditions with combined wave energy often in the low hundreds (335, 322, 408, 290). The swell is coming from the SSW or S, but it’s mostly under 3 ft. The period is long, with some reading 16 to 18 seconds, which is classic groundswell, but there just isn't enough height to get excited about. The wind is a consistent cross-off from the ENE, which keeps the face clean, but the waves are too small to really do much with. This looks more like a spot for the kite crew than for paddle surfing.
The whole first week is a bit of a drought. Thursday morning on the 27th sees a bump to 4 ft but still marginal, and the energy finally climbs into the four digits (1018), but the tide might be working against us. It’s still small and inconsistent.
The real standout comes on Monday, the 7th of September. That morning, the wind goes light offshore from the east, with only a slight air. The swell is still south-southwest at 2 ft, period 18 seconds, and the energy jumps to 543. The forecast says “expect very good surf conditions.” This is the pick of the whole period. The offshore wind and long period groundswell against the reef should make for clean, lined-up waves at Tunnels. It’s small, but for a reef break, those conditions are a treat. Crowds are often here, so if you’re keen, get in early.
The Wednesday morning of the 9th of September also shows some promise with a light breeze from the southeast and a long period SSW swell, rated “expect good surf conditions,” but the energy is a bit lower (393). Still worth a paddle if you miss the 7th.
Overall, there’s a long dry spell until the 7th of September. That Monday morning is the one to circle. The rest is a waiting game with mostly clean but tiny surf.

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.
