The Lowdown
Alright folks, Rusty here with a look at what’s shaping up. We’ve got one spot on the menu, Nungas, and it’s looking like a solid run of waves with a couple of really special moments if you time it right.
Overall, we're looking at a long, consistent stretch of groundswell from the SSW. The energy kicks off Thursday July 30th with moderate combined swell energy (864) but it’s a bit of a slow starter. The wind is cross-off all day, which is good, but the morning is only pushing 3ft at a long 15 seconds, and the afternoon gets a bit more size at 5ft with 14 second periods. It’s a clean start, but the conditions are a bit marginal, so don’t expect perfection just yet.
Friday July 31st sees the swell start to build properly. The morning has 4ft at a very long 17 seconds, with light cross-off ESE winds creating clean conditions. The afternoon is where it gets exciting – 4ft, still 17 seconds, and the conditions are rated as excellent for experienced surfers. The combined energy is moderate (1340), but that long period is a treat at a reef and point setup like Nungas.
The first real standout window is from Saturday August 1st through Sunday August 2nd. Saturday morning serves up 5ft, 16 second swell with clean morning glass, and the afternoon drops to a lighter 10 km/h ESE breeze. Sunday is even better: Sunday morning has 6ft at 16 seconds, and then Sunday afternoon is the highlight of the first week. We get a solid 7ft from the SSW with a very long 17 second period, and the wind swings to a light offshore at 10 km/h from the ESE. The combined energy jumps to a strong 2127, meaning there’s real power in the water. This is expert territory for size, but the offshore wind should make for some absolutely flawless lines on the point. Expect some crowds, as it’s a spot that can get busy when it’s good.
The first week keeps pumping through Monday and Tuesday with 5ft to 6ft swell and consistent cross-off winds. The water temp is sitting at 80° with a normal anomaly, so it’s warm out there for the time of year.
Wednesday August 5th afternoon picks up again, and then we roll into the second week’s big event. From Thursday August 6th right through to Monday August 10th, we’re looking at a sustained pulse of 7ft to 8ft SSW swell with periods of 15 to 17 seconds. The combined energy is strong to very strong, peaking at 3046 Thursday afternoon. The whole period is consistently clean with cross-off winds. The best of the best this week is Sunday August 9th – both morning and afternoon are rated excellent for experienced surfers, with 6ft at 15 seconds and light cross-off winds. This stretch is for the experienced crew, no doubt.
The energy drops a bit on Tuesday August 11th and Wednesday morning, but Wednesday afternoon picks up again. The real kicker is the final day of the forecast window: Friday August 14th. This is the absolute standout of the entire outlook. We’ve got a solid 12ft swell from the SW with a 17 second period. The combined energy is massive – 6032 in the morning and a whopping 6948 in the afternoon. Winds are light and cross-off, 10 km/h from the south in the afternoon. This is an exceptional, expert-only session for those who know the reef and point setup. With that size and period, it’ll be a serious paddle, but the rewards will be incredible. This is the one to dream on, but it’s two weeks out, so keep your fingers crossed. For most other days, that 5ft to 7ft range is where the fun is for a wider range of surfers.
Rusty, signing off.

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.
