The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer at Nungas over the next couple of weeks.

This is a solid run of surf, with barely a flat day in sight. The pattern is a sustained pulse of SW groundswell, and it’s gonna be hanging around for a good long while. The water’s sitting at 80.1°F, which is about average for this time of year, so no surprises there. The standout is late in the window, around Monday the 28th, when it gets serious.

We kick off on Sunday the 13th with a 7.5ft SW swell, period a long 18 seconds. That’s proper groundswell energy – the combined swell energy is a hefty 4029 (moderate to strong). Wind is a cross-off SE breeze at 12 mph, so it’ll be clean but there’s a bit of juice in that wind. It’s a fair size and the long period will see those sets peeling nicely down the reef and point. This one’s a beginner-friendly break, so if you’re getting into it, the size is workable, but that period means the sets will have some push.

Monday the 14th drops a touch to 6.6ft in the morning, still that long 16-second period. The afternoon stays similar. Tuesday and Wednesday keep the 5.9ft to 6.2ft range with 15-second periods, all under light to gentle cross-off breezes. The combined energy is in the 1200 to 1700 range, so moderate, but the quality is there for experienced surfers.

Thursday the 17th morning looks sweet: 6.2ft SW swell, 14-second period, and a light 6 mph cross-off wind. That’ll be glassy and lined up. A proper good session.

The first week wraps up with a gradual drop in size, down to 3.9ft by Saturday the 19th, but the wind stays light and offshore, so longboarders should be stoked.

Now, the real highlight. Sunday the 20th sees a new pulse: 5.9ft SW swell with a period jumping to 17 seconds, and energy climbing back to 1821. Monday the 21st keeps that momentum with 6.2ft and 15-second period. But the absolute best is Monday the 28th. We’ve got an 8.2ft SSW swell, a very long 18-second period, and the combined energy is roaring at 4185 (strong). Wind is a light 6 mph cross-off. This is a big, powerful, clean swell, but that 8.2ft mark puts it firmly in expert territory, especially with that long period. It will be breaking with serious authority on the reef and point. The drop from the 28th is still excellent at 7.9ft on the Monday afternoon.

If you are not an expert, stick to the smaller days in the middle of the week, like Wednesday the 16th or Thursday the 17th, when the swell is 5.6ft to 6.2ft with clean conditions. Crowds are possible here sometimes, but when the surf is this good and consistent, you’ll have company.

This is a fantastic run of surf. Get on 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.
