The Lowdown

G’day, I’m Rusty. Let’s look at what’s rolling in for Nungas.

We’ve got a solid run of surf coming through over the next couple of weeks. Starting off Wednesday July 15th, there’s some proper size on the way, but it’s not for everyone. The swell is hitting 7 ft from the SSW with a very long period of 17 seconds, and the combined energy is strong at 2188. That’s a lot of water moving. The wind is coming from the ESE at 9 mph, blowing cross-off, which will keep the surface clean. Water temp is sitting at 81°, pretty normal for this time of year. This is powerful groundswell, and at a reef and point break like Nungas, it’ll set up some nice lines, but that 7 ft on a long period means it’s an expert-only session. The crowds are labeled as ‘sometimes’ here, so you might have a few others in the water, but it should be manageable.

Thursday July 16th sees the swell drop a touch to 5 ft from the SW, still with a long period of 15 seconds. The energy is moderate at 1129. Wind is stronger though, ESE at 12 mph, and still cross-off. It’s clean, but the conditions are more marginal, so the quality isn’t quite as good as Wednesday.

Friday July 17th is a nice change. The swell settles to 4 ft to 5 ft from the SW, period around 14-16 seconds, and the energy is moderate at 1138. Wind is lighter, SE at 9 mph, cross-off, and the morning is clear. This is a very good surf day for a wider range of surfers—still got that long period push, but the size is more friendly. The afternoon has some clouds and a lighter breeze, so it’s a solid day all round.

The weekend of July 18th and 19th is a bit smaller and more average. Swell hangs around 4 ft to 5 ft from the SW, with periods of 13-15 seconds. Energy dips to around 700-900. Winds are still cross-off and light, but the conditions are only marginal. Not a stand-out, but there’ll be waves.

Now, the real standout is Monday July 20th. Swell jumps back up to 7 ft to 7 ft from the SW, period 17 seconds, and the energy is strong to very strong at 2414 to 2559. That’s the biggest, most powerful day of the outlook. Wind is light, SE at 9 mph, cross-off, and the morning has some clouds but it’s clean. Again, this is expert territory at that size and period.

Tuesday July 21st still has good size, 6 ft from the SSW, period 15 seconds, energy 1523. Clean with cross-off winds. After that, the swell slowly fades. From July 22nd through to the 24th, we’re looking at smaller waves, 3 ft to 5 ft, with periods dropping to 13-16 seconds. Winds stay moderate, but the quality is mixed. There’s a bit of a gap from July 25th to the 27th where the swell really drops off, down to 1 ft to 3 ft, energy getting weak, and the conditions are ordinary to poor. Not much to write home about.

The last few days, from July 28th to the 30th, the swell slowly picks back up but stays small, 2 ft to 3 ft from the SSW/SW, periods 14-16 seconds. Energy is weak to low moderate. The outlook finishes with some good surf conditions on the 30th, but it’s still small.

Bottom line: the best windows are Wednesday July 15th and Monday July 20th for the big, powerful groundswell—experts only. Friday July 17th is the best bet for something a bit more manageable. The rest is a mix of smaller days and a flat patch in the middle.

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.
