The Lowdown
Alright, let's get into it. The surf has been running for a while now and it looks like it's going to keep on going. We've got a solid stretch of SW groundswell pushing through, and the winds are mostly playing nice. It's not going to be epic every day, but there's plenty of waves to be had.
We're starting things off on Friday the 11th. It's a little slow at first at Nungas with a solid 6.6ft of SW swell. The period is a long 16 seconds, so there's some serious power behind it. The energy is strong at 2069, and with a light SSE cross-off breeze, it's going to be clean. The water's sitting at 80.2°, which is pretty normal for this time of year.
The weekend looks like a nice little run. Saturday the 12th has the swell dropping slightly to 5.2ft, but it's still got that long-period push (15s). The morning is looking clear with an ESE cross-off, making for some clean, user-friendly waves. The energy backs off a touch to 1677, but it's still plenty to work with. Sunday the 13th picks up again, with 5.6ft in the morning and a punchier 7.5ft by the afternoon. The period stretches out to 18 seconds, which is about as long as it gets. The energy jumps to 2656 in the morning and then to a beefy 3984 in the afternoon. Winds stay offshore from the SE, but pick up a bit. The morning is the pick of the day, as the afternoon gets a bit more push and could get a little heavy for the average surfer.
Monday the 14th backs off a little, but it's still in the 6.6ft range with 16-second period. The wind is a bit stronger, 20 km/h from the SE, which keeps it clean but with a bit more texture on the surface. The energy is moderate at 1933. It's still surfable, but not as perfect as the weekend.
From Tuesday the 15th through Thursday the 17th, we settle into a groove. Swell hangs around the 5.9ft to 6.9ft mark with 14-15 second periods. The wind is mostly light to moderate SE cross-off, so the conditions stay clean. Energy levels are solidly moderate, hovering in the 1400-1800 range. There's a bit of a dip in quality on Thursday afternoon when the period drops to 14 seconds, making it a little less organized, but still a go.
Friday the 18th and Saturday the 19th see the swell ease off a touch, with 5.2ft to 4.6ft on the cards, but the winds go light. It's looking glassy with light SE breezes, and the energy drops to below 1000, so it's not as grunty, but the waves will be clean and a lot more forgiving. Nice days for a longboard or just getting out there without the hassle.
Now, here's where it gets interesting. Sunday the 20th looks like the standout. The swell jumps back up to 7.2ft in the morning and 7.5ft in the afternoon, with a long 17-second period. The energy is cranking at 2790 and 2711, and the wind is virtually dead in the morning at just 5 km/h from the SSE. This is about as good as it gets. Clean, solid, powerful surf. This is the one to make a plan for.
The following week settles back down into a similar pattern as the start of the run. Monday the 21st through Wednesday the 23rd sees solid, consistent 4.9ft to 6.9ft SW swell with 14-16 second periods and light to moderate offshore winds. Energy is moderate across the board. There's another slight bump on Wednesday the 23rd with the swell picking up to 6.9ft and the period stretching out to 16 seconds. The energy is strong there at 2115 and 2306, and the winds are light. Definitely one to keep an eye on.
The last few days of the run, Thursday the 24th and Friday the 25th, hold onto good consistency, with 4.9ft to 6.2ft SSW swell. Periods drop slightly to 14-15 seconds, but the winds stay offshore and light. It's all good, clean fun.
Then we round it out on Saturday the 26th. The swell backs right down to 3.6ft to 3.9ft, but the period stretches out to a massive 19 seconds. This is straight-up long-period groundswell. The energy is moderate at 1546 and 1618, which is surprising for such a small size, but that long period is giving it some push. The winds are light SSE, so the surface will be clean. This swell will be lining up nicely on the point, but with the period that long, it might be a bit straight on the beach breaks. For a reef and point like Nungas, this is prime. It'll be the perfect way to end the run.
So, the pick of the lot? Sunday the 20th, hands down. The combination of size, power, and that glassy morning wind is a rare treat. Wednesday the 23rd is a close second, but the wind is a little stronger. The rest of the

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.
