The Lowdown

Alright, let’s cut to it. The surf over the next couple weeks is mostly pretty flat, with a lot of small, weak swell and cross-off winds keeping things clean but not really giving us much push. You’re looking at a long run of waist-high waves that don’t have much behind them.

Starting Monday the 14th, we’ve got a tiny 2ft SW swell with a 22-second period – long period, but way too small to do anything. The energy’s weak, only 276, and the 25 km/h NE cross-off doesn’t help. It’s a marginal day at best.

Tuesday the 15th, the swell bumps up a touch to 2ft SW, period 20 seconds. The morning’s got a lighter 15 km/h ENE cross-off, which is the better window, but it’s still small. Afternoon winds pick up to 25 km/h, and the energy’s moderate at 392, but still pretty weak for surfing.

Wednesday the 16th, we’re around 3-3ft SW early, but the period drops to 18 seconds and the wind’s up to 30 km/h ENE. It’s clean, but the quality’s poor. Afternoon’s similar, 3-3ft SSW, period 18, energy 572, but still not good.

Thursday the 17th is more of the same – 3ft SSW/SW, period 16 seconds, winds 25-30 km/h ENE. Energy’s moderate, but the surf quality is just not there.

Friday the 18th, the swell peaks a bit at 3ft from the SSW, period 17 seconds, and the energy’s the highest we’ve seen at 637. Still, the wind’s 25-30 km/h E/ENE, so it’s clean but not great. Marginal at best.

From Saturday the 19th through Sunday the 27th, we’re in a long flat spell. The swell stays between 2ft and 3ft, mostly SSW/SW, periods dropping from 16 seconds down to 13-14 seconds. The energy is weak to moderate, under 500 mostly, and the wind is blowing 25-35 km/h ENE, sometimes more. It’s pretty much a solid week and a half of poor to marginal surf. If you’ve got other things to do, do them.

Now, here’s the good part. By Monday the 28th, the winds start to back off, and that changes everything. The morning has a 2ft SSW swell with an 18-second period, light ENE breeze at 10 km/h, and we’re finally seeing good conditions. The energy is moderate at 391, and it’s clean. That afternoon, the wind goes light offshore at 5 km/h, and the swell’s a touch bigger at 3ft SW, period 18 seconds. That’s a proper glassy window – this is the best it gets.

Tuesday the 29th, the morning’s glassy with a 5 km/h SE wind, and the swell’s 3ft SW with a 16-second period. Energy’s 361, but with that glass, it’ll feel better than the size suggests. The afternoon’s got a few clouds, light 5 km/h NE cross-off, same 3ft SW. Still small, but definitely the cleanest surf in the whole forecast.

So, if you’re looking for the standout, it’s that window from Monday afternoon the 28th through Tuesday the 29th. It’s small, but the light winds and glassy conditions will make it fun. Water temp is about 81°, which is normal for this time of year, so it’s warm. Not big, but definitely the pick of the bunch.

Other than that, it’s a long stretch of nothing, which is pretty normal for here. It won’t stay flat forever, so keep an eye on things. But for now, don’t rush.

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.
