The Lowdown

Alright, mates, Rusty here. Let’s get straight into it.

The next two weeks are looking pretty solid for Nungas. We’ve got a consistent run of clean, cross-off conditions and a decent sized, long period southwest groundswell lining up for most of the period. It’s not going to be flat, that’s for sure. The water’s sitting at a warm 80°, which is about average for this time of year, so you won’t need the thickest rubber.

The first standout is going to be Sunday, August 20th. The swell jumps up to 10ft at 17 seconds, coming from the southwest. The energy reading hits a strong 4303, and with that steady southeast cross-off breeze, it’s going to be pumping. This is proper, powerful surf, so it’s for experienced surfers only—this size isn't messing around. That's your big day.

From there, we ease into a really fun stretch. Monday the 21st stays solid with around 7ft of swell, but the wind picks up a bit to a moderate breeze, so it might get a touch more challenging. Tuesday the 22nd looks mint again, with clean 8ft surf and lighter winds. The following week, from the 23rd through the 25th, stays in that fun, 5ft to 6ft range, still with those clean conditions. It’s a great time to be out there, but it’s not as big as that Sunday.

There’s a little dip around the 26th, where the energy fades and the swell drops off, but it’s not a flat spell—it's just smaller and less exciting. But then it builds back up nicely towards the end of the month. The 27th brings a long period southwest swell at 19 seconds, and while the size is around 4ft, the energy is there. If the period that long, it could be a bit straight at the point, but it’ll still have some punch.

The last few days of the month, from the 28th to the 31st, look really consistent, with 5ft to 7ft surf and those same clean, cross-off winds. It won’t have the size of that standout Sunday, but you can practically set your watch by it. The south wind swings around on the afternoon of the 28th, making it a bit cross, but it should still be fine.

So, for the best waves, mark Sunday the 20th on your calendar. That’s the one. After that, the week starting the 23rd is your best bet for consistent, clean, user-friendly waves.

Rusty out.

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.
