The Lowdown
Alright folks, Rusty here. Look, if you're sitting on your hands waiting for the next few days, you might be a bit disappointed. The surf this week is pretty lacklustre, but hang tight, because the second half of this outlook is where it gets interesting.
We’re looking at Nungas, a reef and point set-up that's fairly consistent. Water temp is about average for this time of year, nothing wild there.
The early part of the week is a write-off. Tuesday the 21st has a pulse of 6ft SW swell rolling in with a 15-second period, which has some grunt (combined energy of 1425). It’s clean with cross-off winds, but it’s a bit of a mess for the average punter. By the afternoon, it drops off into marginal territory. Wednesday through to Saturday the 26th is pretty flat and ordinary, with heights around the 3ft mark and weak energy. It’s surfable, but you’ll be working for scraps.
Now, Sunday the 26th afternoon throws a short, junky 6ft SSE swell with a period of only 8 seconds at Nungas. That’s a lot of churn (835 combined energy) but it’ll be a close-out mess – more of a kite session than a paddle session, to be honest.
Then, we get a bit of a lull until the surf starts to wake up again.
The real standout action starts kicking off from Thursday the 30th. Thursday morning at Nungas sees a clean 4ft SSW groundswell (15-second period) with light offshore winds from the east. Energy is building (680). That’s a solid, clean sign of things to come.
But the absolute best of the bunch? Friday the 31st. Get this: morning glass-off conditions, with a 3ft SW swell riding an 18-second period. The energy is pumping (909) for that size. It’s glassy. It’s clean. It’s a dream window for a point break. The afternoon could get a little cross, but that morning is a gem.
The following week gets even bigger. Saturday the 1st of August sees a solid 4ft to 6ft SW swell, but it’s a bit onshore. Not the pick. Sunday the 2nd is the big one for the experienced crew: a solid 7ft SW groundswell (16 seconds) with clean cross-off winds. The energy is strong (2249). That’s proper, powerful surf. It’s a bit much for beginners, but for the crew who know what they’re doing, it’s a ripper.
Monday the 3rd and Tuesday the 4th keep the energy high with 4ft to 5ft SW swells, with Tuesday afternoon offering another excellent window for experienced surfers (2702 combined energy). By Wednesday the 5th, we’re looking at a 8ft SW pulse (3050 energy) – that’s a serious, expert-only swell. Keep an eye on that one, but it’s a long way out.
So, the takeaway? The first week is a snooze. The best bets are the glassy Friday morning (31st) for the clean, long-period gems, and the Sunday the 2nd of August for the powerful, experienced-only groundswell. The rest of the time, you’ll be waiting for the sets.
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.
