The Lowdown
G’day, Rusty here. We’ve got a solid run ahead at Nungas stretching right across the 16-day window. This is a reef and point set-up, fairly exposed to the dominant SW swell, and it’s a consistent performer. Water temp’s sitting at 80°, dead average for the time of year, so nothing weird there.
We kick things off on Tuesday, September 1st. Morning's looking clean with a cross-off breeze out of the ESE pushing at 12 mph. Swell’s a proper 7 ft from the SW, period a very long 18 seconds—this is groundswell with serious grunt. Combined energy is right up there (2684), so it’s strong. That long period makes it a treat at this point break; the waves will have shape and juice, but there’ll be longer lulls between sets. It’s labelled as clean but marginal for tide, so pick your bank. By afternoon it’s similar but wind eases to a gentle 9 mph from the SSE.
Wednesday 2nd keeps the pace: 7 ft SW swell in the morning, still cross-off, energy high (2561). The afternoon is a step up in quality—solid 7 ft, 16-second period, and a score that points to excellent surf for experienced surfers. The cross-off breeze is light, the faces will be clean. This swell is pushing towards 8 ft by Thursday afternoon, so it’s getting into expert territory but the reef setup handles it well.
The standout of the first week is Thursday 3rd afternoon: 5 ft SW swell, 16-second period, clean cross-off winds. It’s not the biggest but the combo of shape and no chop makes it a joy for those who know the break. Early in the second week, Monday 7th morning offers another gem: 7 ft SSW swell, 14-second period, light cross-off and in the morning the energy’s solid (1759). It’s clean and lined up for the point.
Look ahead to Tuesday 8th afternoon: swell bumps to 8 ft SSW, period 18 seconds—very long period groundswell again. Energy is massive (3716). That’s big and clean, but it’s for experienced surfers only. Thursday 10th morning is a beauty: 7 ft SSW at 17 seconds, light ESE breeze at just 6 mph. The energy is still strong (2672) and conditions are “excellent” for experienced surfers. That’s probably the pick of the whole run—clean, powerful, and well-shaped.
Later in the second week, from Monday 14th onward, we see a gradual drop in size. Swell stays around 5 to 6 ft SW, periods around 15-16 seconds, and the cross-off breeze holds. Wednesday 16th morning: 6 ft SW, 15 seconds, light 6 mph ESE wind. Clean and fun for all levels. Afternoon is the same story. Crowds are possible at Nungas, especially on a run this long and consistent, but the point gives plenty of room.
So if you want the best: Thursday 10th morning is the standout. Clean, strong, and well-shaped. Honourable mention to Tuesday 8th afternoon if you’ve got the experience for the size.
Signing off, 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.
