The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards at Nungas.

Right off the bat, we’ve got a solid run of surf lining up. The first few days are a bit of a mixed bag, but from late Thursday 5th September things really start to build. The water’s sitting at a warm 80°, which is pretty much bang on average for this time of year, so no surprises there.

Thursday 3rd September kicks things off with clean, cross-off breeze, but the swell is a bit messy. The combined energy is strong at 1545, with a clean 6ft SW groundswell, but the report flags it as marginal. Friday 4th is still clean but a little smaller, around 5ft. Honestly, it’s not the best start, but the wind stays favourable.

Now, Saturday 5th September afternoon is where it starts to get interesting. The swell bumps up to 7ft from the SSW, with a long 16-second period. The combined energy jumps to 1832, solid moderate-strong. The wind is a gentle cross-off, and the surf is rated excellent for experienced surfers. This is a standout window for the crew who know what they’re doing – that’s a powerful, clean swell at a reef and point set-up, which loves a long-period SSW groundswell. It’s going to be proper.

Monday 7th and Tuesday 8th September keep the quality high with consistent 7ft to 6ft SSW swell, long periods and clean conditions. The energy stays well into the thousands. It’s a solid run of good waves, all with that gentle cross-off breeze. Great paddling conditions.

The real highlight though, is Wednesday 9th September. Morning sees the biggest swell of the whole run at 8ft from the SSW, with a 16-second period and combined energy of 3152 – that’s strong, powerful surf. The wind is a gentle cross-off, making it clean. This is only for the experienced – at over 8ft, it’s a big, heavy day at Nungas. If you’ve got the skills, this is your session.

After that, the swell backs off slightly but stays really good all the way through to the middle of the second week. The week starting Monday 14th September looks promising again with another pulse of 8ft to 8ft SW groundswell, plenty of energy, and clean conditions. By Wednesday 16th September, it’s still around the 7ft to 7ft mark.

The run finally fades out around Friday 18th September, dropping to 5ft, but still clean and fun for any level.

In summary: The standouts are Saturday 5th afternoon and Wednesday 9th September. Saturday 5th is a fantastic, powerful 7ft SSW groundswell with clean wind – a true highlight. Wednesday 9th is the big daddy at 8ft, expert only, but absolutely firing if you’re up for it. The whole stretch from the 5th to the 14th is a classic run of consistent, quality groundswell and light offshore winds.

Stay safe, and get amongst it.

Rusty.

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.
