The Lowdown
Alright folks, Rusty here. Let’s chew the fat on what’s coming for Nungas. This is a reef and point set-up that’s fairly consistent and loves a south-west swell, so we’ve got a proper run of waves ahead.
The water temp is sitting at 80.4°F with a tiny anomaly of 0.7°F, so it’s pretty much average for this time of year – nothing crazy, just your usual warm water.
We’re starting on Thursday the 23rd of July with a clean 3.9ft SSW swell, period around 14 seconds, and a gentle cross-off breeze. The combined energy is moderate (530). It’s a solid kick-off – clean, fun waves that are good for a beginner-friendly session. The crowds are only sometimes an issue here, so you might get a few out, but it’s nothing to stress about.
Friday morning, the 24th, drops a bit to 3.3ft, still clean but the energy is a touch lower (469). The wind picks up a bit, but it’s still cross-off, so it’s surfable. Friday afternoon is smaller again at 2.6ft, and the energy drops to 241 – that’s weak, ordinary stuff. Not worth getting too fired up about.
Saturday the 25th shows a little more push: 3.6ft in the morning, period hitting 15 seconds, and the energy bumps up to 644. The wind stays cross-off. It’s a clean, long-period groundswell, which at a point and reef break like Nungas should line up nicely. Expect some proper shaped waves, but with that longer period, the sets will be a bit more spaced out. Saturday afternoon holds at 3.3ft, still clean.
Sunday the 26th brings a shift – the swell direction swings to the SSE, and the period drops to 9 seconds. That’s shorter period, windswell-type energy. The height is 3.9ft, but the combined energy is around 524. The wind is a moderate breeze at 12-16 mph, still cross-off, but the shorter period means the waves will be a bit crumbly and less organised. It’s okay, but nothing special.
Monday the 27th is a write-off. The morning has 3.3ft from the S with a period of just 8 seconds – that’s poor energy (260) and the report calls it poor surf conditions. The afternoon drops to 1.6ft but with a very long 17-second period, so the energy (279) is still weak. That’s a gap day.
We get a bit of life back on Tuesday the 28th. The morning shows 3.0ft from the SW, period 16 seconds, and the energy (432) is moderate. The wind is a gentle cross-off. The report says “good surf conditions,” so it’s a clean, lined-up swell. The afternoon is similar at 2.6ft.
Wednesday the 29th starts to build. The

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.
