The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell on the horizon for Nungas, so let’s break it down.
The overall pattern is a slow build from a clean, mid-period SSW groundswell that starts off modest but gains serious steam as we push into the start of August. The first few days of the forecast are a bit of a warm-up, with the real fireworks kicking off towards the weekend and following week. After a strong peak, the energy eases but stays very much rideable through the second week.
We kick off on Tuesday the 28th of July with a clean 3.0ft to 2.6ft SSW swell at 16 seconds. The wind is a gentle cross-off breeze, keeping the surface clean. The wave energy is moderate (483). It’s a manageable start, perfect for getting a few in without too much fuss.
Wednesday the 29th sees a bump up to 3.9ft, still from the SSW and with a period of 15 seconds. The wind picks up a touch to a moderate breeze, but it’s still cross-off, so it’s clean. The swell energy is starting to build (630). The commentary flags it as marginal, but honestly, for a Wednesday morning session, it looks fun.
Thursday the 30th is a bit of a mixed bag. The morning is still clean with 3.3ft at 15 seconds, but the wave energy jumps significantly by the afternoon to 4.3ft with a powerful 1166 energy reading. The wind is a light cross-off. It’s looking good for a sunset paddle.
Now, Friday the 31st is where things start to get interesting. The morning is a little fresh with a moderate breeze, but the swell is 4.3ft at a very long 17 seconds. The afternoon, however, is the first real standout. The wind drops to a gentle breeze, the swell holds at 4.3ft, and the wave energy is a strong 1268. The commentary says “expect very good surf conditions.” This is your first call of the run.
Saturday the 1st of August is where the experts need to start paying attention. The morning is crystal clear with a light breeze. The swell bumps up to 4.6ft from the SSW with a 16-second period, and the wave energy is pumping at 1491. The commentary calls it “excellent surf conditions for experienced surfers.” The afternoon pushes up to 5.2ft from the SW.
Sunday the 2nd of August is a serious standout. The morning is clean with a gentle breeze, 5.9ft of SSW swell at 16 seconds, and the wave energy is a massive 2006. The afternoon gets even better – 6.9ft from the SSW, 17 seconds, and a wave energy of 2572. Both sessions are flagged as “excellent surf conditions for experienced surfers.” This is the peak of the first week. The swell is getting big, so this is for the solid crew.
Monday the 3rd of August continues the run with 6.2ft in the morning and 5.9ft in the afternoon, both with clean conditions and light winds. The wave energy is still very strong (1689 and 1337). Another top-tier day.
Tuesday the 4th of August the swell starts to dip slightly to 5.6ft, but it’s still a very good, clean day with a gentle cross-off breeze.
We hit a bit of a lull in the middle of the second week, but then Wednesday the 5th of August throws a curveball. The morning is a bit of a question mark with a 4.6ft swell at a very long 21 seconds. The period is so long it might be a bit straight for a beach break, but Nungas being a reef and point setup, it should handle it well. The afternoon, however, is a cracker: 5.2ft at 20 seconds, clean, light breeze, and a wave energy of 3114.
Thursday the 6th of August is another huge day for the experienced crew. Morning sees 8.2ft at 17 seconds with a wave energy of 3643. The afternoon is 7.9ft with a light breeze. This is proper heavy groundswell.
Friday the 7th of August is still solid

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.
