The Lowdown

Alright, Rusty here, and I’ve got the scoop on the Nungas stretch for the next couple of weeks.

Alright, so the pattern for Nungas looks like a solid block of surf, but you’ve gotta read the small print. There’s a south-west swell running for the whole stretch, but it’s pretty much always coming in with a cross-off or cross wind, which is never perfect. The first few days are a bit of a tease. The real gold starts to show up around the middle of the first week, and the second week looks promising, but it’s the long-range stuff you have to keep an eye on.

Let’s start from the beginning. Wednesday the 2nd of September, we have a solid 6.9 ft south-west groundswell with a very long period, and the combined energy is strong (2561). That’s a lot of water moving, but it’s a cross-off wind, so it’s clean but not glassy. It’s a bit of a "marginal" call on the tide. The water temp is about average for the time of year.

Thursday the 3rd, the swell drops a touch to 5.9 ft, same long period, and the energy is still strong (1545). Still a cross-off ESE wind, so the waves are clean but have that slight push from the side. The morning is the better call.

Friday the 4th, the swell backs off to 4.3 ft, but the period drops to 14 seconds, and the energy is moderate (748). The afternoon sees a bit of cloud cover and a 4.6 ft swell, but the numbers jump to 810. There’s a note saying "expect very good surf conditions," which is a little more optimistic, but the winds are still side-shore.

The first real standout for me is Saturday the 5th morning. The swell jumps back up to 5.9 ft from the SSW, and the wind is a light SE breeze at 6 mph. That’s almost offshore, and the energy is moderate (1240). It’s a clean, cross-off wind, and the waves will be a lot more fun. The afternoon gets a bit of a cross wind, so the morning is the call.

Now, Sunday the 6th is a bit of a write-off with a moderate breeze and a cross-chop developing. The swell is 6.2 ft, but the energy is strong (1991), and the condition is "marginal." The wind is picking up, so it’s going to be bumpy.

Monday the 7th is where it gets exciting. The morning session has a 6.9 ft SSW swell, a light breeze, and the forecast says "excellent surf conditions for experienced surfers." The combined energy is strong (1911), and it’s clean. The swell is over 6.6 ft, so it’s getting into the territory where beginners should be careful, but for anyone who knows what they’re doing, this is the best of the first week. The afternoon is just as good.

The rest of the first week is a mix of moderate to strong swells, but the winds are a constant cross-off. Tuesday the 8th has a massive 4.3 ft swell with a 20-second period, which is about as long as it gets, and the energy is strong (2170). That’s a long, clean groundswell, but it’s going to pitch pretty straight at the beach. Nungas is a reef and point, so it should handle it well, but be ready for the long lulls between sets.

Looking into the second week, the pattern holds. The real highlight for the entire 16-day window, in my opinion, is Friday the 11th of September. The morning has a 6.2 ft SW swell, a light breeze, and the energy is strong (1719). The forecast is "excellent for experienced surfers," and it’s clean. That’s a beautiful setup. The afternoon is just as good.

Saturday the 12th is also a good call, with a 5.2 ft swell and a 15-second period, and the energy is still strong (1769) in the afternoon. Clean, cross-off winds.

The later part of the second week, around the 13th and 14th, has some big numbers again. Sunday the 13th afternoon sees a 6.9 ft SW swell with a 17-second period, and the energy is very strong (2422). That’s a lot of water, and it’s a clean, cross-off wind. For experienced surfers only.

The last few days, from the 15th to the 17th of September, are all showing "excellent surf conditions for experienced surfers" with consistent 5.2 ft to 6.9 ft swells, and the wind is often a light breeze. That’s a solid run of quality.

So, the best on offer? If you can only go once, make it Monday the 7th of September for the morning session, or if you’re looking at the second week, Friday the 11th of September morning is the standout. The crowds at Nungas can be "sometimes" busy, so expect a few crew out there, but it’s a reef and point, so it spreads out a bit.

This is a long run of surf, and the consistency is "fairly consistent," so you’ve got a lot of options. The swell is coming from the SW, which is exactly the optimum direction for this spot. It’

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.
