The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’re looking at a solid run of South West swell hitting Nungas, a reef and point set-up that loves a SW direction. The water’s sitting at a warm 81°F which is about average for this time of year, so no surprises there. The overall pattern is a long, drawn-out pulse of energy that starts a bit average but builds into something special.

The first few days are a bit of a warm-up. Wednesday the 2nd and Thursday the 3rd have some size, around 6ft to 7ft, with a long 16-17 second period, but the wind is a moderate cross-off so it’s clean enough. The energy is strong though, with readings in the 1500-2500 bracket, so there’s punch. The surf quality is just okay, not a complete write-off.

Friday the 4th and Saturday the 5th see the swell drop a little to 5ft-6ft, but the period stays solid and the wind is a gentle cross-off. The energy drops to moderate levels (around 800-1200), but the conditions are much cleaner. Saturday afternoon gets a bit of cross-chop, so the mornings are the go.

Now, here’s where it gets interesting. Starting Tuesday the 8th, the swell really starts to turn on. Tuesday morning has a 4ft swell with a very long 20-second period, but the energy is still high at 2248. That’s a classic groundswell – amazing shape but it might be a bit too straight for a beach break, but Nungas being a reef and point, it’ll handle that beautifully. Tuesday afternoon is a standout: 8ft at 18 seconds from the SSW, with a huge energy reading of 4457 and clean, gentle cross-off winds. That’s expert territory, but the quality is excellent.

The real highlight, though, is Sunday the 13th. The morning session shows a solid 10ft swell from the SW at 18 seconds, with a massive energy reading of 5419. The wind is light and cross-off, making for clean, powerful waves. This is the biggest and best on offer, but it’s strictly for experienced surfers at that size. The wave quality is excellent, and the consistency is there. Crowds are possible at Nungas, so get in early.

The following week keeps the goodness going. Swell holds around 8ft to 8ft through the 14th, 16th, and 17th, with periods of 15-17 seconds and clean cross-off winds. The energy stays strong, between 2500 and 3400. Solid surf for anyone who knows what they’re doing.

So, the best on offer is hands down Sunday the 13th morning for the big, clean groundswell, and Tuesday the 8th afternoon for that first big pulse of long-period energy. If you’re not an expert, stick to the 5ft-6ft days around the 4th and 5th, or the 6ft clean days on the 11th and 12th.

Rusty out.

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.
