The Lowdown

Alright folks, Rusty here. Let’s get into it.

The next couple of weeks are all about Nungas, and it’s a pretty solid run. We’ve got a persistent, long-period SW groundswell lining up, and the wind is mostly behaving itself. The water is sitting at 80.4°, which is pretty much bang on average for this time of year, so no surprises there.

The action starts on Monday, August 31st. Nungas is seeing a clean 5ft swell from the SW, with a very long 18-second period. The combined energy is pushing through at 1697, which is moderate to strong. It’s a gentle cross-off breeze, so things will be looking tidy. This is a beginner-friendly reef and point break, so it’s a great place to get amongst it.

Tuesday, September 1st, the swell kicks up a notch. Morning sees 7ft, and by the afternoon we’re at 7ft from the SW, with that same juicy 18-second period. The energy jumps to 2912, and the wind stays clean and cross-off. It’s getting a bit more serious, but still very manageable.

The swell holds through Wednesday and Thursday, bouncing between 5ft and 7ft. The period drops a touch to 16-17 seconds, but the energy stays solid, and the wind remains cross-off. It’s that classic, clean mid-period groundswell that Nungas just loves.

Friday, September 4th, sees a bit of a dip. Swell drops to 4ft-5ft, with a 14-second period. The energy is down to 756-810, but it’s still clean and rideable. A good day for a longboard or a foiler.

Now, the standout window. Saturday, September 5th, through the following week, things get exciting. On Saturday afternoon, the swell bumps up to 6ft from the SSW, and the energy is charging at 1699. Sunday, September 6th, the morning starts at 6ft, and by the afternoon we’re looking at 8ft from the SSW with a 17-second period. The energy explodes to 4081. That’s strong wave energy, and it’s going to be powerful. The wind goes cross-shore, so there will be a bit of texture, but it’s still very surfable.

The real highlight is shaping up for Wednesday, September 9th, and the following weekend. Wednesday morning, Nungas is pumping 8ft from the SSW, with a 16-second period and a clean cross-off breeze. The energy is a massive 3101. This is expert territory – over 8ft, you need to know what you’re doing. It’s a beast.

Then, the absolute best of the best. Friday, September 11th, and Saturday, September 12th, are looking incredible. Friday morning, another 8ft SSW swell, 17-second period, clean cross-off wind, and energy at 3407. Saturday is similar, with 7ft from the SW and clean conditions. The period drops to 15 seconds, but the consistency is there.

Finally, the run ends with a bang on Sunday, September 14th. Monday morning, we’re looking at 8ft from the SSW, 17-second period, clean cross-off, and energy at 3763. That’s a lot of juice. It’s a big, powerful groundswell. For a reef and point like Nungas, that’s going to produce some serious, long, walling waves. The best sessions are definitely on the 11th, 12th, and 14th. The longer period means fewer waves in a set, but the ones that come will be worth the wait. Get ready.

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.
