The Lowdown
G'day, Rusty here.
Look, the next couple of weeks are a bit of a mixed bag for Nungas. The real standout action is a long way off, but there's a solid pulse of energy coming through. The water's sitting around 81°, which is pretty much what you'd expect for this time of year.
We've got a bit of a slow start. Tuesday morning the 21st of July is the first real call, with a solid 6ft groundswell out of the SW. The period is a meaty 15 seconds, so you're getting proper lines. The combined energy is a hefty 1411 (strong wave energy), and the wind is a light cross-off from the SE. This is proper surf for experienced surfers only – too big for beginners. It's a reef and point break, so that long period will wrap in nicely. It's fairly consistent, but crowds are possible, so get in early.
The rest of that week and into the next is pretty ordinary. The swell drops right off, with a lot of marginal days and a few with poor conditions. The 27th of July is a write-off, and the 28th is only just showing a glimmer of a 3ft swell. The swell ticks up a bit on the 29th of July (Wednesday) with a 4ft SSW swell, but nothing that's going to have you calling in sick.
Now, the real highlight is a long way out. Later in the period, things start to get very interesting. The 30th of July afternoon sees a 3ft groundswell, but the period is a stunning 19 seconds, and the energy jumps to 1210 (moderate wave energy). The wind is light, and it's rating as very good.
But the true standout is Wednesday the 5th of August. That morning, we've got a 8ft SSW groundswell with a 16-second period and a massive combined energy of 3669 (very strong wave energy). The wind is a light cross-off from the ESE. This is a long-range call, so it's promising but not locked in. This is expert territory only. That afternoon, the wind drops to a light breeze from the SSE, the swell is still 8ft, and the energy is 3607. It's clean, powerful, and all for the experienced crew. Earlier in the week, the 1st and 2nd of August also have some solid 6-6ft SW swells, but with more wind, so they're not the top pick.
So, for the patient ones, the 5th of August is the clear winner. The setup looks more interesting for paddle surfing than kite surfing given the reef and point nature of the break. Get ready for a big 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.
