The Lowdown
Alright, Rusty here. Let's get into it.
We've got a solid run of swell headed our way for Nungas. This is a reef and point set-up that's fairly consistent, and it's going to be working for a good stretch. The water temp is sitting about average for this time of year, so nothing unusual there.
The action kicks off on Thursday, 6th of August, with a clean 7ft SSW groundswell, period around 18 seconds. That's a long-period groundswell, which means plenty of energy and nice, shaped waves. The ESE wind is cross-off, keeping things clean. This is definitely for experienced surfers at that size, but the quality is there. Friday, 7th of August, builds slightly, with 7ft to 8ft SSW swell, still clean in the morning, though the afternoon sees a shift to a cross-shore wind, making it a bit more marginal. Saturday, 8th of August, is similar, with that 8ft SSW swell, but the afternoon gets a bit of cross-chop. Sunday, 9th, cleans right back up, dropping slightly to 7ft, but still a great wave.
Now, the standout window is Monday, 10th of August, through Tuesday, 11th of August. On Monday afternoon, the swell jumps back to 8ft from the SSW with a period of 18 seconds, and the combined energy is massive. The wind is a light cross-off, making for clean conditions. This is a top-tier session. Then Tuesday, 11th of August, is the peak. We're looking at a solid 10ft SSW groundswell, with a period of 17 seconds, and the energy readings are huge. The wind is a clean cross-off all day. This is serious, powerful surf, only for the very experienced. The long period will make those sets line up beautifully on the point.
The swell drops a touch mid-week, with 6ft to 7ft SSW through Wednesday and Thursday, still clean and very surfable. Friday, 14th of August, sees a weird one: the size drops to 4ft, but the period jumps to a very long 23 seconds, giving a deceptive energy reading. That's a low-tide, ultra-long period groundswell that'll wrap around the point nicely.
The second week gets a bit trickier. The weekend of the 15th and 16th of August has some solid 8ft SSW swell, but the winds are up to 12-15 mph from the ESE and SE. It's still cross-off, so it's rideable, but the higher wind will put some texture on the surface. The energy is still strong, so it's worth a look, but the quality drops off. By Monday, 17th of August, the swell is dropping to 6ft, and the wind goes more cross-shore, creating a cross-chop. It's a definite step down.
The real second-week standout, and it's a promising one, is Wednesday, 19th of August. We've got a fresh injection of 7ft SSW swell, period 18 seconds, and the energy is back up. The wind is light from the SE, making it glassy clean. This is a long-range call, so not as certain, but it looks like a beauty. The morning of Thursday, 20th of August, holds that 8ft SW swell, still clean, before the series slowly winds down into the 21st.
So, the best of the best? Lock in Monday afternoon, 10th of August, and all of Tuesday, 11th of August. Tuesday is the king, with that 10ft SSW groundswell and massive energy, but it's a heavy one. Monday afternoon is a slightly more comfortable 8ft with the same excellent quality. For the long-range bet, keep an eye on Wednesday, 19th of August. That one has real potential.
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.
