The Lowdown
Alright folks, Rusty here. Let’s get you up to speed on what’s comin’ through over the next couple of weeks.
First up, we’ve got a solid run of surf settling in right away. The water temp is sittin’ at 81°, which is pretty much bang on average for this time of year, so nothin’ weird there.
We’re lookin’ at Nungas, a reef and point set-up that’s fairly consistent and handles a SW swell real nice. The first few days, Friday the 17th through Sunday the 19th, are steady with clean, cross-off winds. Swell hangs around 4ft to 5ft from the SW, with a really long period of 14 to 16 seconds—that’s proper groundswell energy. The combined energy is strong, sittin’ between 670 and 1170. It’s a good stretch for any level, but keep in mind that long period stuff can make the waves a bit straight at beach breaks; here at the point and reef, it’ll line up real nice.
The standout window opens up Monday the 20th into Tuesday the 21st. Monday afternoon, the swell jumps to 7ft from the SW with a 17-second period, and the combined energy cranks up to 2525. That’s powerful, clean, and with light winds—this is the pick of the first week. Tuesday morning is still solid at 6ft from the SSW, with energy at 1532. These are for experienced surfers only; if you’re not comfortable with overhead, punchy waves, sit this one out.
The middle of the week sees a drop-off. From Wednesday the 22nd through to the end of July, the swell backs off to 3ft to 5ft, and the energy drops way down to a few hundred. The wind stays cross-off, but it’s a bit stronger, and the conditions are just ordinary. A few morning sessions on the 24th and 25th might give you a clean 3ft wave, but it’s nothin’ to write home about.
Now, here’s where it gets interesting again. Lookin’ ahead to the end of the month, Friday the 31st of July and Saturday the 1st of August ramp up big time. Friday morning you’ve got 5ft with a 21-second period from the SW—that’s an incredibly long groundswell, energy at 1803. By Friday afternoon, it’s 7ft from the SSW, 18 seconds, and energy jumps to 3052. Saturday holds at 7ft to 8ft, still SW, with energy around 3000. This is a heavyweight swell, only for the experienced crew. The wind stays light to moderate and cross-off, so it’ll be clean, but that’s a lot of power. This long-range call is promising, but keep an eye on it as it gets closer.
So, overall, the best on offer is Monday the 20th afternoon and the double-header of Friday the 31st and Saturday the 1st. Surf’s up.

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.
