The Lowdown
Alright folks, Rusty here with the long-range look at what's coming our way.
We've got a solid stretch of surf on the cards here, with barely a day that's not worth a look. The standout period is clearly the first few days, but there's quality spread across the whole 16-day window, so get your wax ready.
The pattern is all about consistent, quality S/SSW and SW groundswells pumping in. The energy is pretty impressive across the board, with readings mostly in the four-digit range, showing moderate to strong wave energy. The optimum swell direction for Nungas is SW, and we see that plenty, so the breaks will be working well.
Kicking things off on Thursday the 3rd, we have a solid 6ft SW groundswell with a very long 16-second period and a cross-off breeze at 12 mph from the ESE. It's clean but the report flags marginal conditions, possibly due to tide. The good news is the energy is strong at 1545. Friday the 4th drops a little in height to 5ft, but it's still clean and the energy sits around 810-833 – still plenty of push for a beginner-friendly reef and point wave.
Now, the true standout of the whole forecast is Sunday the 6th. The morning session at Nungas is looking prime: 6ft of SSW swell at 14 seconds, with a cross-off breeze leaving it glassy clean. The combined energy is a hefty 1991, and the report calls it excellent for experienced surfers. The afternoon pushes up to 8ft with a 17-second period and 2987 energy, though it gets a bit of a cross-shore chop. Even so, the morning is the session to circle on the calendar. The water temp anomaly is unremarkable, so expect it to be about normal for this time of year.
We roll through the next week with a mix of good and excellent conditions. Monday the 7th stays solid at 7ft, Tuesday the 8th sees a mellow drop to 5ft but with an 18-second period – that's very long period groundswell, so energy will be jacking up and the sets will be spaced out, making paddling out easier. That could be a good day for a less experienced surfer looking for cleaner waves at a point or reef. By Wednesday the 9th we're back up to 8ft in the morning with a huge 3263 energy reading and clean conditions – that's getting into expert territory. The morning on Thursday the 10th also looks excellent with 5ft and clean conditions. The Friday the 11th and Saturday the 12th both have excellent mornings, with the Saturday afternoon also getting a nod for excellent conditions.
The second week here keeps the momentum. Sunday the 13th and Monday the 14th are both excellent, with Monday the 14th looking particularly special: 7ft in the morning with a light 6 mph breeze making it glassy, and energy at 2931. The afternoon bumps up to 8ft with 3029 energy and is still clean. Tuesday the 15th and Wednesday the 16th remain clean but with moderate energy. Thursday the 17th and Friday the 18th both offer very good conditions with clean cross-off winds, keeping the fun rolling right to the end of the forecast window.
Keep in mind, with all this long period groundswell coming from the SW, Nungas, being a reef and point set-up, is the perfect place for it. The longer period will mean better-shaped, more powerful waves but longer lulls between sets. The crowds at Nungas can be an issue sometimes, so get in early.
Bottom line: the first week has the biggest punch, but the whole 16 days are stacked. Don't sleep on it.
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.
