The Lowdown

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

We’ve got a solid run of surf coming up at Nungas, a reef and point setup that’s fairly exposed to the southwest swell. The water temperature is right around average for this time of year, so nothing freaky there. The first proper window opens up on Monday morning, August 31st, and it’s pretty much game on from there with barely a gap.

The early part of the week, from Monday the 31st through Wednesday the 2nd of September, serves up clean, cross-off wind conditions with swell heights starting around 4 feet and building to 7 feet. The swell’s coming from the southwest, which is the optimum direction for this spot, and the periods are long, between 16 and 19 seconds. That’s groundswell energy, giving the waves real shape and punch. The combined swell energy is strong, so there’s plenty of power in the water. The mornings are a bit cleaner, but those afternoons still look good. Crowds are sometimes a factor here, so have a look, but it’s not always packed.

The standout for the first week is Wednesday afternoon, September 2nd. You’ve got a 7-foot southwest swell with a 16-second period, and the conditions are just excellent. The wind is a gentle cross-off, keeping the face smooth. This is one for experienced surfers, as the size and power are real.

Through the rest of the week, the swell dips a little but stays solid, with good energy through Thursday and Friday. The winds stay cross-off, and the waves stay clean. By Saturday, September 5th, the swell drops to 5 feet, and the wind is a light breeze, making for a more mellow session. The next big highlight, and the best of the whole forecast, hits Sunday, September 13th. The afternoon session has a 10-foot southwest swell with a 17-second period, and the combined energy is massive. The wind is a gentle offshore breeze. This is big, powerful, and clean. Only for experts, and it’s going to be a serious session.

The following week, from the 8th to the 15th of September, it stays solid. The swell is consistently between 5 feet and 10 feet, with the same southwest direction. The winds are generally cross-off or light cross-shore, keeping things clean. The confidence is higher for the near-term, but the long-range standouts, like that Sunday the 13th, are looking very promising. The 15th of September is a beauty too, with an 8-foot swell and light offshore winds.

This is a great run for Nungas. The consistency is there, the wind is on your side, and the swell is from the right direction.

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.
