The Lowdown
Hey, Rusty here. Let’s break down Nungas for the next couple weeks. Water temp's about 80°F, which is normal for this time of year, so you won't need a thick suit.
From Tuesday, September 15th, we get a steady diet of SW groundswell. Swell runs 5 to 7 feet (SW) with periods between 14 and 15 seconds – that's proper long-period groundswell, perfect for a reef and point like this. Winds are light to gentle cross-off, keeping things clean as a whistle. Combined energy is solid moderate to strong (1535 to 1724), so there’s plenty of juice. This is for the experienced surfer; 6 feet and up gets hairy for beginners.
Friday the 18th and Saturday the 19th ease a touch to 4 to 6 feet, still clean and fun. Then Sunday the 20th and Monday the 21st, the swell picks back up to 6 to 7 feet with longer 16 to 17 second periods (energy around 1700 to 2190). More power, wider sets – beautiful shape.
The next week stays good, with another solid pulse on Wednesday the 23rd at 7 to 7 feet (SW, 16 secs). Surf holds steady chest to head-high through the 25th.
Now, the absolute standout: Saturday, September 26th. Swell jumps to a massive 10 feet (SSW) with a very long 20 second period in the afternoon. Combined energy is a whopping 7861. That’s expert-only territory. Winds are gentle cross-off, so you’re looking at clean, thumping, heavy lines. Sunday and Monday stay huge at 8 to 10 feet.
If you’re newer, hit the smaller mornings around the 19th or 22nd (around 4 to 5 feet). For everyone else, this whole stretch is a winner. Crowds can show up, especially on the best days, but that’s part of it.
Rusty out.

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.
