The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Nungas over the next couple of weeks. We’ve got a run of solid, consistent SSW groundswell on the horizon, so don’t bother dusting off the longboard just yet. This is a stretch that’s going to build and keep on giving, with mostly clean conditions. The water temp is sitting right around average for this time of year, nothing weird there.
The opening salvos on Friday the 31st of July are a bit of a warm-up. We’re looking at 4.3ft of SSW swell with a very long 17-second period. That’s proper groundswell. The cross-off wind keeps it clean, but the energy reading of 1330 is moderate, so while the waves will have nice shape, they’ll be a bit lazy. Not a standout, but a good sign of things to come.
The real action starts to crank up from Saturday the 1st of August. Saturday morning the swell bumps up to 4.9ft from the SSW, still a long period of 16 seconds, and the conditions are primo with a light cross-off breeze. By Saturday afternoon we get glassy conditions, with the swell easing slightly to 4.6ft from the SW. That afternoon session will be silky clean. That’s your first real taste of quality.
Sunday the 2nd of August is where it starts to get serious. The swell pushes to 6.2ft in the morning, and then 6.6ft in the afternoon from the SSW, period holding at 16-17 seconds. The energy is climbing into solid three-digit territory – 1881 in the morning and 2102 in the afternoon. That afternoon, with offshore wind and clean lines, is the standout of the first week.
We roll through the first week of August with solid 5.6ft to 7.2ft SW/SSW swells, plenty of energy in the 1100-1600 range, and predominantly clean cross-off or light offshore breezes. The whole week is good, but Thursday the 6th of August afternoon brings a jump in size to 7.9ft with that classic 17-second interval and an energy reading of 3276. That’s a big step up. This is expert territory.
Heads up for the second week. Saturday the 8th of August still has 7.9ft from the SSW, 16 seconds, and a clean morning. Sunday the 9th of August afternoon is a monster: 8.2ft, 17-second period, SSW, and a clean cross-off breeze. The energy is a whopping 3685. That’s a very, very powerful swell.
The real crowns of the forecast, though, are Thursday the 13th, Friday the 14th and Saturday the 15th of August. Thursday the 13th morning sees 7.9ft of SSW power with an 18-second period. The energy reading is 4547, which is just massive. Friday the 14th is the absolute peak: an 11.5ft SSW swell on Friday morning with a 17-second period, light cross-off breeze, and an energy reading of 6224. That afternoon is still 9.8ft and 6139. Saturday the 15th morning holds at 9.8ft, 16 seconds, and 4276 energy. This whole sequence is insane. But a word of caution: that’s 10ft-plus surf, purely for experienced surfers. For anyone else, it’s a spectator sport.
The one spot on the menu is Nungas, a reef and point. It’s a fairly consistent break and it’s fairly exposed to the SW swell, which lines up perfectly with the optimum direction (SW). Crowds are possible here, but with the size and quality on tap, it will be worth jostling for a wave. Keep in mind that long-period swells like these can run a bit straight on the open beach, but this is a reef/point set-up, so it’ll handle the power, shaping up those long, drawn-out walls.

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.
