The Lowdown
Alright, Rusty here, and let’s talk about your local waves.
Alright, we’ve got a solid run of surf coming up, and I mean a proper stretch. The water's sitting at a balmy 80°, which is totally normal for this time of year – no weird temperature swings to worry about. The standout session looks to be this Friday, the 28th of August. We’ve got a chunky 8ft SW groundswell with a period of 17 seconds rolling in, and the energy is massive, way up there (4161). The wind is coming from the ESE at 9 mph, holding it clean. This is proper, heavy swell though – over 8ft means it's for experienced surfers only. That long 17-second period is going to stack up nicely at a reef and point setup, but watch out at the beachies where it might race straight. For the best of it, head to Nungas.
Friday afternoon hangs in there with 8ft SW swell, a touch less energy (3808) but still very clean with lighter SSE winds.
Saturday the 29th stays solid with 7ft SW swell in the morning and 6ft in the afternoon, both clean with cross-off breezes. The energy is still strong (2246 and 1610). Still a bit punchy for beginners at that height.
We start to ease off Sunday the 30th into smaller but still fun 5ft SW swell, and the wind stays favorable. Energy drops to a moderate range (870-940). Surf gets easier for a wider range of paddlers here.
Monday the 31st see a weird spike in period with a 4ft SW swell but a 19-second period – that’s a very long period groundswell for that size. It'll be clean, but that super long period might make it a bit too straight at the beach. Energy is moderate (1391).
Then we get a boost again from Tuesday the 1st of September through Wednesday the 2nd, with solid 7ft to 7ft SW swell and clean conditions. The energy is back up in the strong range (2684 - 2575). Tuesday morning has a moderate breeze at 12 mph, but still offshore enough to keep it clean. Tuesday afternoon looks like the pick of that little block.
Thursday the 3rd and Friday the 4th see a gradual drop back down to 5ft - 5ft swells, still with clean cross-off winds. A great, manageable size for a lot of people.
The second week (from September 6th onward) keeps offering up rideable, clean surf. Nothing giant, but consistent. A late-period pulse looks like it could fire up around Friday the 11th and Saturday the 12th of September. The 12th is looking promising with 8ft SW swell again and very high energy (3622), and winds look good. That’s a long way out though, so keep an eye on it – it's a promising call, not a guarantee.
Overall, it’s a busy period with very few gaps. The big Friday (Aug 28) and the following Tuesday (Sept 1) are the real highlights for the bigger stuff. If you're looking for clean, fun waves without the size, the mornings from the 30th onwards are your friend. Crowds are possible at Nungas (sometimes), so pick your session.
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.
