The Lowdown
Hey folks, Rusty here. Let’s talk about what’s shaping up at Nungas for the next couple of weeks. It’s a reef and point break, beginner-friendly, and pretty open to swell. Water temp is about 80°, right where it should be for this time of year.
We’ve got a solid run of surf starting now. The real highlight comes in the middle of next week. Sunday the 9th gets things going with a 8ft SSW groundswell at 16 seconds, cross-off wind from the SSE at 9 mph, clean but not epic. Wave energy is strong at 2486.
Monday the 10th steps it up. Morning has 6ft SSW swell at 14 seconds, light cross-off breeze from the SE at 6 mph, clean, energy at 2702. By afternoon, swell jumps to 8ft at 18 seconds – that’s a long-period groundswell, light wind, excellent for experienced surfers. Energy pumps at 4129. Tuesday the 11th is the big day: 10ft SSW swell at 17 seconds in the morning, clean with a gentle 9 mph cross-off, energy at 4394. Afternoon hits 10ft at 16 seconds, energy roaring at 5798. This is heavy, powerful surf – not for beginners.
From Wednesday the 12th through Saturday the 16th, the swell settles to 5ft to 7ft, periods 14 to 17 seconds. Winds stay light to gentle, cross-off, so the waves will be clean. The reef and point handle that long-period energy well. Energy stays moderate to strong, 1785 to 2331. Good solid surfing.
Second week kicks off Monday the 17th with 6ft, a bit less energy. Tuesday the 18th morning brings 5ft SW swell at 18 seconds – interesting long-period but smaller. Afternoon jumps to 8ft at 16 seconds with a moderate 12 mph breeze, still cross-off. Wednesday the 19th looks big: 8ft in the morning, 10ft in the afternoon, winds up to 16 mph moderate breeze, but cross-off keeps it clean. Energy is massive, 4578 to 4714. Thursday the 20th morning is another standout: 10ft SSW swell at 16 seconds, wind drops to 9 mph, cross-off, energy at 4027. That’s a top session for experts. Afternoon gets a little cross-shore chop, so go early.
Friday the 21st through Sunday the 23rd stays consistent: 7ft to 8ft swells, clean, moderate to light winds. Energy stays above 2000, peaking at 3593 Sunday afternoon. Then Monday the 24th finishes strong: 10ft SSW swell at 17 seconds, light 6 mph SE breeze in the morning, energy at 4924. Afternoon holds at 8ft with similar conditions.
Best bets: Tuesday the 11th and Thursday the 20th morning – big, clean, powerful groundswell with light winds. Beginners, stay on the beach those days. Crowds are possible at Nungas, so get there early.

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.
