The Lowdown

Alright, let’s get into it.

The next couple of weeks are looking pretty solid, with a lot of consistent swell activity lined up for the region. We’ve got a good run of surf starting this Saturday, so get your boards ready.

We kick things off on Saturday morning at Nungas. It’s a reef and point setup, fairly consistent, and the water is sitting at 80.1°, which is right about normal for this time of year. There’s a clean 6ft SSW swell pushing through with a 14-second period. The energy is strong at 1249. The light SE cross-off wind will keep it nice and glassy. It’s a bit of a softer start, but it’s surfable.

Sunday sees the swell bump up a touch to 6.5ft, still from the SSW, and the 14-second period keeps it clean. The SE cross-off wind is still there, making for some really good conditions. The energy jumps to 1766. This is a much better day, and the morning session is the pick. Into the afternoon, the wind shifts more southerly, which brings a little bit of cross-chop, but it’s still workable.

Monday keeps the momentum going with similar 6.5ft SSW swell and clean, cross-off winds all day. The energy stays consistent around 1770. There’s good shape to be had, especially through the morning. Tuesday eases slightly to 6ft before dropping a bit in the afternoon to 5ft, but that afternoon swell is carrying a much longer 18-second period, and the energy is up to 2934. This is a proper groundswell, and it’s going to be powerful, with long waits between sets. Nungas being a reef and point will handle this beautifully.

Wednesday, the swell kicks up again, hitting 8ft in the morning. That’s starting to get sizeable, and the cross-shore winds will add some texture to the surface. The period is a solid 16 seconds, with energy at 3504, which is very strong. This is getting into expert territory, and the quality is a bit more marginal. Thursday backs down a touch to 6.5-7ft, and the winds return to that clean cross-off. The energy is still high, with a 15-16 second period, and it should be really fun again.

Friday and into the weekend, we’ve got some really sweet conditions. Friday sees 7ft SW swell with a long period, and the winds are light and offshore. Saturday is slightly smaller at 5.5ft, but that light cross-off wind and clean conditions will make it a fun day in the water, even with a possible afternoon storm risk.

The standout of this whole run looks like Sunday the 13th. The morning has 6ft of SW swell, but it’s packing a huge 19-second period, and the energy is at 2813. That’s very long-period groundswell, and Nungas will be doing its thing, offering up some beautifully shaped rides. By the afternoon, it’s 7ft, and the energy is up to 3192. This is the pick of the fortnight, in my opinion.

After that, the swell remains fun and consistent through the following week, mostly in that 5ft to 7ft range, with SW and SSW directions and clean conditions. There are still plenty of good waves on offer, but nothing with the same power and magic as that Sunday.

Crowds are a possibility at Nungas, but with this quality of surf, it’s worth dealing with a few other heads in the water.

So, to sum it up – don’t sleep on this window. From this weekend through the middle of next week, there are plenty of waves. But if you can, make the call for Sunday the 13th. That’s the one that’s got my stoke levels high.

Information about the Nungas Surf forecast

The above surf forecast table for Nungas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nungas can be found by selecting the local surf guide option on the grey menu. Our Nungas 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 (Nungas) 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 Nungas 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.
