The Lowdown
Alright, Rusty here. Let’s check out what’s going on.
We’ve got a solid run of surf coming to Nungas, a reef and point set-up that's fairly consistent and handles a good SW groundswell. The water temp is about average for this time of year, so nothing wild there. The standout period is the first week – no doubt about it. The overall energy is strong, building from Sunday the 2nd right through the following week.
Sunday the 2nd kicks off with a clean 6 ft SSW groundswell with a very long 16-second period. The combined energy is a massive 1922, so there’s plenty of grunt in the water. The wind is a gentle cross-off breeze, keeping things clean. This is for experienced surfers – the size and power mean it’s not a beginner’s day. Monday the 3rd drops a touch to 6 ft but the period stays long at 15 seconds, with clean conditions and light offshores in the afternoon. The energy is still strong at 1245. Tuesday and Wednesday hold steady around 5 ft, with clean cross-off winds and consistent energy around the 1000 mark.
Then Thursday the 6th cranks up again. The morning has 7 ft SSW swell, a 18-second period, and the combined energy jumps to 2462. The wind is cross-off, so it’s clean, but this is serious size and power. The afternoon sees 8 ft swell and energy climbing to 2987. Friday the 7th pushes even bigger – 8 ft in the morning, 8 ft in the afternoon, with energy hitting 3817. This is big, powerful groundswell and only for experienced surfers. Saturday the 8th stays at 8 ft all day, with energy around 3834 and 3319, and the wind stays cross-off. Sunday the 9th drops a little to 7 ft but holds strong energy at 2359. The wind freshens a bit in the afternoon to 12 mph, but it’s still cross-off.
The best of the best? For me, Sunday the 2nd and Thursday the 6th stand out. The 2nd has that perfect combo of first-day swell, very long period, and clean conditions. The 6th has the raw power and still clean wind. Both are for experienced crews only.
The second week gets a bit more mixed. From Monday the 11th, the energy is still huge – 10 ft in the morning with 4155 energy, but the wind goes cross-shore in the afternoon, introducing a bit of chop. The 12th and 13th settle back to 5 ft-6 ft with cleaner conditions, and the energy drops to the 1400-1600 range. The 14th is smaller at 4 ft-5 ft, and the wind goes cross in the afternoon, so it’s less appealing. The 15th bounces back to 6 ft with 16-second period and clean cross-off winds. The 16th and 17th hold around 5 ft-6 ft but the wind picks up a bit, especially Monday the 17th with a 12 mph cross-off.
Overall, Nungas is firing in the first week. The long-period groundswell is best handled at this reef and point set-up, but it’s not a spot for beginners when it’s over 5 ft. If you’re an experienced surfer, the first few days are the pick. The second week has some windows, but the size and conditions are less consistent.
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.
