The Lowdown

Alright, this is Rusty. Let's have a look at what's on the menu for the next couple of weeks.

We've got one spot firing, and it's all about Nungas. This reef and point break is sitting pretty, and it's going to be a solid run for the crew who can handle it. The water temp is sitting about average for this time of year, so no surprises there.

The whole stretch kicks off on Sunday the 9th of August. We're looking at a solid 8ft SSW groundswell with a very long 16-second period. That's a lot of energy pushing in (2751), and with a light cross-offshore breeze, it's going to be clean. But heads up, this is a big, powerful swell. At 8ft, it's getting into the realm where only experienced surfers should be out there. The waves will have serious push and long gaps between sets, which makes paddling out easier, but those sets will be heavy. The coast is fairly exposed to the swell, and the optimum direction is SW, so this SSW swell is a near-perfect match.

The consistency is good, and you'll be sharing the water with others – it says crowds are sometimes here, so be ready for a few others in the lineup.

The standout period is Tuesday the 11th of August. Monday afternoon is already pumping with a 8ft, 18-second swell (3844 energy), but Tuesday morning and afternoon are the pick. We're seeing a 10ft swell from the SSW with a 17-second period in the morning, jumping to a 16-second period in the afternoon. The combined energy is massive – 4447 in the morning and a whopping 5798 in the afternoon. Winds are light and cross-offshore, keeping it glassy. This is big, powerful, and clean. If you're a confident surfer, this is the day to be in the water.

The swell eases a bit through the end of the week, but it stays in the 5ft to 7ft range with that long period, so it's still excellent. By the weekend of the 15th and 16th, we're back into the 6ft to 7ft SSW swell, with light winds and clean conditions. The energy is still significant (over 2000).

Then there's a bit of a drop-off around Monday the 17th, with the swell dipping to 5ft and the energy dropping to 993. Still good waves, but noticeably smaller.

The second week looks promising, but with a bit more caution needed. Swell builds again from the 18th, with a 6ft SW swell on Tuesday morning, building to 8ft by Wednesday the 19th. The wind stays light and cross-offshore, so it stays clean. The energy is back up over 3600 on Wednesday. The biggest call is Thursday the 20th, with a 8ft SW swell but the wind turns more cross-shore, creating a bit of chop. Friday the 21st is still big (8ft) but the wind gets stronger in the afternoon, making it less ideal. The weekend of the 22nd and 23rd looks cleaner again with smaller, fun waves.

For the groms and beginners, this is a heavy stretch. Over 5ft it's getting big, and over 8ft it's experts only. With the long period and the point break setup, the waves will be well-shaped and powerful, but definitely not one for the learner.

Overall, the absolute standout is Tuesday the 11th of August at Nungas. The combination of a deep, 10ft SSW groundswell and glassy, light offshore winds is about as good as it gets. Get on 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.
