The Lowdown
Alright folks, Rusty here. We’ve got a solid stretch of waves coming our way, so let’s get into it.
The setup is pretty straightforward: we’re looking at a long, consistent run of groundswell from the SSW, pushing in at a nice long period. The water temp is about average for the time of year, nothing crazy there.
The first real action kicks off on Wednesday the 30th of July. Nungas is a reef and point setup that’s fairly exposed to this SSW swell. On Thursday morning, we’re seeing a clean 3ft swell from the SSW with a period of 15 seconds. The wind is a light cross-offshore breeze, keeping things tidy. The energy is ramping up, with a combined swell energy reading of 844 (moderate energy). It’s a bit on the smaller side but it’s a start.
Friday the 31st of July is where this gets more interesting. The morning shows a 4ft SSW swell, still with that 17-second period (very long period groundswell), which is going to wrap nicely into the point. The wind is a light cross-offshore. By the afternoon, the wind drops to a light breeze, and the forecast says to expect very good surf conditions. The swell energy is strong at 1280 (moderate to strong energy). This is a promising start to the weekend.
The standout of the first week has to be Saturday the 1st of August. The morning is clear with a 5ft swell from the SSW, still a long 16-second period. The wind is a gentle cross-offshore breeze. The combined swell energy is a solid 1523 (strong energy). The forecast is calling for excellent conditions for experienced surfers. This is the best of the bunch early on. The wave quality is going to be really good.
Sunday the 2nd of August brings a bit more size but still manageable. The swell bumps up to 6ft in the morning, hitting 6ft in the afternoon with a 17-second period. The wind stays light and cross-offshore. The energy jumps to 1955 (strong energy) in the afternoon. Another excellent day for those who are comfortable.
The week that follows from Monday the 3rd to Wednesday the 5th of August stays consistent. We’re looking at 5ft to 6ft SSW swell, with periods between 14 and 15 seconds. The wind is a steady cross-offshore breeze, keeping the conditions clean. The energy is strong, sitting between 1000 and 1546. It’s not as big as the weekend, but it’s very surfable.
Now, we get into the second week, and the size really starts to build. From Thursday the 6th of August, the swell is pushing 7ft, and it just keeps climbing. By Saturday the 8th of August, we’re looking at a solid 8ft of SSW swell with a 17-second period. The wind is a light to gentle cross-offshore breeze. The energy is massive, hitting 3874 (very strong energy). This is expert territory. The wave quality is still excellent, but this is not for the faint of heart. The swell continues to run strong through the 9th, 10th, and 11th, with 8ft to 8ft waves. The wind stays mostly favorable, though there are a few sessions with a cross-shore wind that will put a bit of chop on the surface. The energy is through the roof, sitting between 2000 and 4270.
The final sessions around the 12th and 13th of August are still packing a punch, with 7ft swells and a 16-second period, and the wind is light and clean, so the quality holds up.
Overall, the best single day on offer is the Saturday the 8th of August. That 8ft, 17-second SSW groundswell hitting the point with light winds is the cream of the crop. It’s a big, powerful, clean swell for experienced surfers only. The Saturday the 1st of August is a close second for the smaller, but still excellent quality.
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.
