Alright, Rusty here, let’s have a look at what’s on the cards for the next couple of weeks.
We’re looking at a long, busy run of pulses at Nungas, a reef and point that’s fairly consistent. The water temp is sitting at 81°, which is a touch warmer than average for this time of year – nothing crazy, but you’ll be comfortable in a spring suit or just boardies.
The first real action kicks off on Sunday the 12th of July. The afternoon brings some clouds and a light SE breeze whipping cross-off, which will keep things clean. We’ve got a solid 3ft SW groundswell pushing in at a very long 13 seconds – that’s proper energy. The combined swell energy is 397 (moderate), so it’s not a monster, but for a beginner-friendly spot, this is a good, clean entry point. The swell direction is straight out of the SW, which is exactly what this break wants to see.
Things take a step up in size from Tuesday the 14th through to Wednesday the 15th. Tuesday morning sees 6ft SSW swell with an 18-second period – that’s deep ocean energy. The combined energy jumps to 2119 (strong). By Wednesday afternoon, we’re looking at 6ft SSW swell at 16 seconds, with a clean SE cross-off breeze. The swell is getting a bit meaty – over 5ft – so it’s getting away from beginners, but for experienced surfers, Wednesday afternoon shapes up as the standout window. The combined energy is 1787 (strong), and the waves will have good shape.
There’s a real highlight on Monday the 20th of July. The afternoon brings 8ft SSW swell at 17 seconds – that’s a serious groundswell – and the combined energy hits 3224 (very strong). This is a heavy day, only for experts. The SE cross-off wind keeps it glassy, but at this size, the point will handle that long period better than a beach break would. Keep your wits about you.
The last real standout lands on Saturday the 25th of July. The afternoon sees 6ft SSW swell, with an 18-second period and a light SSE breeze. The combined energy is 2708 (very strong). Again, this is a confident, powerful swell that will line up nicely on the reef, but it’s still a clean, manageable size for experienced surfers.
There’s a gap with no real standout surf in the second week aside from the 25th, but the consistency is good, and the forecast can always change. For now, point your board at the 15th and the 20th of July.
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.
