The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of swell on the way for Nungas kicking off Tuesday the 14th, but this is a spot that really demands respect. The first few days serve up proper groundswell with very long periods – we’re talking 17 to 18 seconds – which means heaps of energy and long waits between sets. The combined energy is strong, hitting over 2000 (2119-2544) on Tuesday and Wednesday, so those waves will have real push. The swell is coming from a SSW direction, which is a bit off the optimum SW, but the reef and point setup here should still handle it well. The water temperature is about average for the time of year, nothing unusual there.
Tuesday the 14th sees waves around 6ft to 6ft with a cross-off wind from the ESE-SSE. The wind is a light to moderate breeze, keeping things clean, but the surf is really only for experienced surfers given the size and power. Wednesday the 15th is the standout – swell bumps up to 7ft in the morning, still that long 17-second period, and again that cross-off breeze keeps the face clean. The energy is massive (2372). This is peak stuff, but at over 7ft, it’s definitely expert territory. Thursday the 16th drops back a notch to 5ft-5ft, but the wind picks up a touch, making it less inviting.
Friday the 17th through Sunday the 19th settles into a nice, consistent 4ft-5ft range with a 14-16 second period. The wind stays cross-off and light, so the waves will be clean and fun. The energy is moderate (862-1162). This is where the less experienced crew can have a crack, but the crowds are possible here so expect company.
There’s a gap in the real quality from the 16th to the 19th, with only fair to good conditions. Then Monday the 20th brings another pulse – 7ft to 7ft, 17-second period, and the energy jumps back to over 2500. That afternoon session on the 20th looks excellent for advanced surfers again. The following week (21st-28th) sees a slow decline with swell dropping to 2ft-4ft, and the energy fading to 400-800. The winds remain mostly cross-off and light, so it’ll stay clean, but the juice is gone. The best of the second week is probably the 25th afternoon with a 3ft SW swell and 18-second period – clean but small.
Overall, the standout sessions are the 15th and the 20th. Those are the ones to circle. Big, long-period groundswell, clean conditions, and serious power. This is not a beginner’s game. If you’re an experienced surfer, get out there. The rest of the window is okay but nothing to write home about.
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.
