The Lowdown

Alright, let’s get into it.

We’ve got a solid run of surf on the cards here at Nungas. This is a reef and point break that’s fairly exposed to a SW swell, and it’s fairly consistent, which is a good sign. The water’s sitting at around 80°, which is about average for this time of year, so nothing unusual there.

The forecast kicks off this Sunday the 13th with a SW swell around 6 ft, but the morning’s a bit marginal – tide might be playing tricks. The wind is cross-off from the ESE at 12 mph, so the ocean’s clean but the conditions are just okay. Combined energy is strong, up at 2603, so there’s plenty of push. Sunday arvo the swell bumps to 8 ft, still a cross-off, but that’s getting up there for the less experienced. It’s still clean, though.

Monday the 14th sees the swell hanging around 6 ft from the SW, period a long 16 seconds. The morning is still only marginal, but by Monday afternoon things sharpen up: wind drops to 9 mph from the SE, and the conditions turn excellent for those who know what they’re doing. That long period means the wave face will be nice and lined up – this point setup will love it. Energy is still moderate at 1764.

Tuesday the 15th through Thursday the 17th keeps delivering. You’re looking at 6 ft to 6 ft SW swell with that lovely 15-second period, and the wind stays a light to gentle cross-off. Tuesday morning is excellent, Wednesday morning too. Thursday morning is the standout for me – the swell is 6 ft, period 14 seconds, and the wind is just a light breeze from the SE at 6 mph. That is glassy potential. Energy is solid at 1563. This is your best bet early in the week. Crowds can show up here sometimes, so get in early.

Friday the 18th eases a touch to 6 ft, still clean, still good vibes. The weekend of the 19th drops to 4-5 ft, but the wind stays light, so the longboarders will be smiling.

Now, look ahead to the following week. Sunday the 20th sees a pulse of energy come back – 6 ft to 7 ft SW swell with a 17-second period and combined energy hitting 2025. That’s a groundswell with serious legs. The wind is still cross-off, so it’ll be clean but that’s a lot of water moving – only for the experienced. The best of the second week is probably Thursday the 24th and Friday the 25th, with swell around 6 ft to 7 ft from the SSW, combined energy strong, and the wind dropping to a light 6 mph. These mornings look excellent. A little less certain this far out, but promising.

The last few days, Saturday the 26th and Sunday the 27th, hold 7 ft to 7 ft SSW swell, still with light winds. The energy stays in the 1500-2200 range. This is expert territory but the quality is there.

The standout pick: Thursday morning the 17th at Nungas – 6 ft SW swell, 14-second period, light breeze at 6 mph, cross-off, clean. That’s your session.

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.
