The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles.
We’re looking at a solid run of groundswell for Nungas, a reef and point break that’s fairly consistent and loves a SW swell. The water’s at 81°F, which is about average for the season.
The week starts Saturday afternoon, July 18th, with a clean 5ft SW swell at 15 seconds. That’s a long period groundswell, and the energy is already moderate (873). Winds are cross-off from the SSE, so the waves will be clean and lined up. Great for the beginners.
Sunday morning, July 19th, drops a little to 4ft SW, still 14 seconds, but the wind picks up. The energy is still there (706), but it’s a bit of a wait-and-see. Afternoon is similar.
Then Monday, July 20th, is a real standout. Monday morning has 5ft SW at 15 seconds with a jump in energy (1898). The wind is cross-off from the SE, and it’s clean. The afternoon pumps harder: 7ft SW at 17 seconds, energy roaring at 2514. That’s strong wave energy, and the point break will be on fire. This is the best of the first week. The afternoon is getting into expert territory, so if you’re not solid, stick to the morning.
Tuesday, July 21st, morning holds 6ft SW at 15 seconds (1420 energy) but rain showers are in the mix. Still, the wind is manageable. Tuesday afternoon drops off a bit.
From Wednesday, July 22nd, through Saturday, July 25th, we’re in a lull. Swells drop to 3ft to 4ft, periods shorten, and the energy dips into the hundreds. It’s marginal, but the wind stays cross-off, so it’s not a total write-off for a longboard.
Sunday, July 26th, through Monday, July 27th, is still small. Not a standout.
Now Tuesday, July 28th, the energy builds. The afternoon brings 5ft SSW at 17 seconds, energy at 1416. A sign of things to come.
Wednesday, July 29th, morning is another highlight: 6ft SSW at 16 seconds, energy at 1510. Winds are light and cross-off. Clean and powerful.
Thursday, July 30th, and Friday, July 31st, are solid. Friday afternoon is a beast: 5ft SW at 19 seconds, energy at 2015. That’s strong wave energy, and the point will be reeling. This is a top call for the second week.
But the real cherry on top is Saturday, August 1st. Both morning and afternoon pump 8ft SW at 18 seconds with energy over 4200. That’s very strong energy. This is solidly in expert territory. The point break will handle it, but it’s a serious slab.
Sunday, August 2nd, drops to 8ft and 8ft, still big, with energy in the 3000s. The wind stays cross-off, but it’s for the crew who know what they’re doing.
So, the standout days: Monday, July 20th (morning is the best all-rounder), and Friday, July 31st (afternoon) for that long period power. Saturday, August 1st, is for the experts only.
Rusty, signing off.

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.
