The Lowdown
G’day, it’s Rusty. We’ve got a solid run of surf coming up here at Nungas — no waiting around, it kicks in right from Friday the 14th. This is a reef and point set-up that handles a SW swell beautifully, and we’ve got a lot of that on the way. The water’s sitting at 80°F, which is bang on average for this time of year, so no surprises there.
Friday the 14th gets things rolling with a clean 6 ft SSW swell, period a long 15 seconds — that’s proper groundswell. The energy’s already pumping at 1589 (moderate to strong). Winds are light cross-off from the SSE at 9 mph, so the face should be smooth. This is excellent for experienced surfers, and honestly, that’s the whole run: this spot gets good, but when the swell pushes over 8 ft it’s strictly for the crew who know what they’re doing. Crowds? They show up here sometimes, so you’ll have company, but the quality makes it worth it.
Saturday the 15th steps up a notch: 6 ft to 7 ft, SW direction, period holding at 17 seconds — even longer. Energy climbs to 2606 by the afternoon. Winds stay light and cross-off, so it’s still clean. Sunday the 16th is similar, 7 ft dropping to 6 ft, still 16-second period. Monday the 17th eases a touch to 5 ft, still clean, still good.
Now, Tuesday the 18th: the swell dips to 4 ft in the morning but the period is 16 seconds and the energy is surprisingly punchy at 1953. The afternoon picks up to 6 ft. But the real standout — and I mean the standout of this whole outlook — is Wednesday the 19th and Thursday the 20th. Wednesday morning hits 8 ft at 19 seconds from the SW, with combined energy of 4368. That’s strong, and the wind is a light cross-off from the ESE at 9 mph — glassy conditions. Thursday the 20th holds 10 ft, same 16-second period, energy still up around 4367. That is serious, powerful groundswell. Only for experienced surfers. The point break nature of Nungas will handle that long period beautifully — no straight closeouts.
Friday the 21st backs down to 7 ft, still clean. Saturday the 22nd is 7 ft to 8 ft. Sunday the 23rd drops to 6 ft. Monday the 24th: morning is 4 ft with an 18-second period (2028 energy, interesting), but the afternoon gets a bit windier with a moderate breeze at 12 mph — still clean, but the score drops slightly.
Tuesday the 25th is back to solid 6 ft, clean. Wednesday the 26th: morning is smaller at 5 ft, but the afternoon brings a 4 ft SW swell with a 20-second period and 1568 energy — super long period, very clean, light winds. Thursday the 27th jumps back up to 8 ft with moderate breeze, cross-shore wind, so it’s a bit choppier. Friday the 28th and Saturday the 29th taper off, with 6 ft down to 5 ft, periods still long. The morning of the 29th has a 5 ft, 18-second swell with 1838 energy — still worth a look if you’re keen.
All in all, Wednesday the 19th and Thursday the 20th are the pick of the bunch — big, clean, powerful groundswell. That’s where I’d be pointing my board.
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.
