The Lowdown

Alright, Rusty here again, switching to feet and Fahrenheit for you.

Let’s start with the opening act. Friday the 4th through Sunday the 6th is pretty quiet. We’re looking at waves around 4ft to 5ft from the S and SSW, blown by a moderate cross-off ENE wind. Water temp is a warm 81°F, which is dead average for this time of year. The swell energy is in the moderate range (751 to 518), but the forecast is marginal. Not worth getting wet for.

Come Monday the 7th, things fire up. The morning brings a solid 6ft from the SW, with a 14-second period and a true offshore wind from the E at 16 mph. The energy jumps to 2005 – that’s strong. The real gold is Monday afternoon. Swell hits 8ft from the SW, with a very long 15-second period and a massive energy reading of 3659. The wind stays offshore from the SE at 16 mph. This is powerful, long-period groundswell and it’s for experienced surfers only. At Tunnels, that SW swell will wrap in beautifully, but it’ll be serious. This is the best window of the whole outlook.

Tuesday the 8th is still okay, but weaker. Morning has 6ft from the WSW with an 11-second period and cross-off wind, energy at 1612. The afternoon drops to 5ft from the SSW, but the period falls to 8 seconds – short-period, less punch.

From Wednesday the 9th onward, it’s a long stretch of tiny surf. Waves drop to 1ft to 3ft, with a stubborn cross-off wind from the ENE at 12 to 19 mph. The only glimmer is Saturday the 19th, with light, glassy wind from the SE, 3ft from the SSW, and a 15-second period. Energy is moderate (501-560). It’s a long way out, so keep an eye on it. For now, the call is clear: Monday the 7th afternoon is the standout. Don’t miss it.

Rusty out.

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.
