The Lowdown
Alright, Rusty here, let's talk about what's coming up for Nungas.
First up, the water temp is 81°F, which is pretty much what you'd expect for this time of year – nothing unusual there.
The next couple of weeks are a bit of a mixed bag to be honest. We've got a few days of "marginal" surf from Wednesday the 22nd through to about Tuesday the 28th. The swell is mostly in the 2ft to 4ft range from the SSW/SW, with periods around 13 to 17 seconds, so it's a long-period groundswell. The wind is cross-off from the SSE/SE, which keeps things clean, but the wave energy is just lacking. You'll see combined energy values between 259 and 671 (moderate), so it's weak. Honestly, it's surfable but nothing to write home about.
Things start to look a bit more promising from Wednesday the 29th. The swell picks up to 4ft from the SSW, period 14 seconds, and the combined energy jumps to 732 (moderate). By Thursday the 30th, we see a big jump in energy, with a reading of 1103 (strong) in the morning, and then a massive 1665 (strong) in the afternoon as the swell period stretches out to 19 seconds. That's a very long period groundswell. The swell is 4ft to 4ft from the SSW. This is the kind of energy that will really light up that reef and point setup at Nungas.
Now, the standout period is from Friday the 31st of July through to Sunday the 2nd of August. This is the best on offer. Friday the 31st is looking excellent, with 4ft to 4ft SSW swell, periods of 17 to 18 seconds, and combined energy readings of 1372 and 1378 (strong). The wind is a gentle cross-off, so it'll be clean. This is prime for experienced surfers, as the swell is getting up there but not too big.
Saturday the 1st of August is also very good, with the swell building to 5ft to 5ft from the SSW. The combined energy hits 1659 (strong) in the afternoon. The wind remains light and cross-off. This is solid, consistent surf.
The pick of the whole run, though, is Sunday the 2nd of August. We're looking at a solid 8ft to 8ft SSW swell, period 16 seconds, and the combined energy is in the 2800 to 3152 range (very strong). This is serious, powerful groundswell. The wind is a light cross-off, so it will be clean. However, at over 8ft, this is only for experts. The long period will make it break a bit straight at the beach, but this reef and point should handle it beautifully. If you're a skilled surfer, that's the day to be out.
After that, from Monday the 3rd through to Thursday the 6th, the swell drops back but remains in the 5ft to 7ft range, with combined energy readings between 1014 and 2257 (strong to very strong). The wind is a bit stronger, with moderate breezes, making it a bit more challenging. It's still surfable, just not as clean as that peak on Sunday.
To sum it up, the early part of the run is ordinary. The best window is from Friday the 31st of July through to Sunday the 2nd of August, with Sunday being the absolute standout for experts. Saturday the 1st is the best bet for strong intermediate surfers. Don't sleep on Friday the 31st either.
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.
