The Lowdown
Alright folks, let's get into it. This is Rusty, and I'm looking at the next 16 days for Nungas. We've got a slow start, but patience is gonna pay off in a big way.
Nungas is a reef and point setup, and it's pretty consistent. The water temp is sitting at 81°F, which is a touch warmer than usual for this time of year—about 2°F above average, so it's a nice little anomaly to have.
The first solid action doesn't really kick in until the afternoon of Monday the 20th. We see a jump in size with a clean 7ft swell from the SW, with a period of 17 seconds—that's a proper long-period groundswell. The combined energy is strong, clocking in at (2443). This is excellent for experienced surfers only, as anything over 8ft is for experts. It stays solid through Tuesday the 21st with a 6ft SW swell, showing moderate to strong energy (1410), but it's a bit more marginal.
The standout window, the one you circle on your calendar, is from Monday the 28th of July through to Saturday the 1st of August. This is where it gets really good. We've got a solid run of SW groundswells with periods of 16 to 18 seconds and consistent heights around 5ft to 6ft. The combined energy readings are strong, with values like (1792) and (1862) on the 28th, and peaking at (2527) on the afternoon of the 31st. The winds are light and cross-off from the SE or SSE, which will keep the face clean. This is excellent surf for experienced surfers, and the consistent, long-period swell will make for some well-shaped, powerful lines on the point. Just keep in mind, with a long period like that, the sets will have some gaps, but the paddle-out should be easier.
There's also a promising pulse on the 31st of July and the 1st of August, with 6ft to 6ft SW swells and very strong energy (2203 and 1908). The direction is straight out of the SW, which is the optimum for this break. It's a bit further out, so it's less certain, but the potential is there.
The second week has a few smaller pulses, but the real power is focused on that end-of-July, start-of-August stretch. The rest of the time, you're looking at smaller, more marginal surf.
Alright, keep your eyes on the horizon for that late July run. That's the one.
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.
