The Lowdown

G’day, Rusty here. Let’s be honest about New Brighton Beach for the next couple of weeks – it’s a pretty quiet stretch. The ocean’s not offering much for us, and most of the 16 days are looking flat or unsurfable. There are a couple of tiny chance, but nothing to get worked up about. Expect long dry spells with no decent waves.

We start on Wednesday the 19th of August, and this is honestly the best it gets. At New Brighton Beach, there’s a small 1ft SSE groundswell pushing in with a nice long 15-second period. The combined energy is moderate at 186. The wind’s blowing offshore from the WSW at 9 mph, so it’ll be clean. It’s not big, but that long period means the waves will have some shape and decent gaps. The water temp is average for this time of year. It’s a learner-friendly size, but remember this spot is inconsistent, so you might be waiting a while between sets.

That same Wednesday afternoon, the swell holds around 2ft from the east, but the period drops to 10 seconds and the wind goes cross-off. Still surfable, but nothing flash.

From Thursday the 20th of August all the way to the end of the month, it’s a desert. Day after day of tiny 0.7ft to 1ft waves with poor conditions, onshore winds, or flat energy. The combined swell energy drops as low as 15-18 – basically flat. You’ll see a couple of glassy mornings, but there’s no push in the water. This is a proper blank run.

Things try to pick up on Thursday the 27th of August, but it’s ugly. A 4ft NE windswell shows up, building to 4ft with moderate combined energy, but the wind is howling onshore at 19 mph from the NE. The period is a short, junkie 5-6 seconds. That’s a choppy mess – more of a kite day than a paddle session.

Then, on Friday the 28th of August, we get the most promising pulse. In the morning, a 4ft ENE groundswell rolls in with a 9-second period. The combined energy jumps to a solid moderate 253. The wind is a light offshore from the WNW at 6 mph, keeping the surface clean. This is the standout window of the whole forecast. The size is right at the edge of beginner-friendly, but it’s manageable. Just know the wind turns onshore and the surf drops off in the afternoon.

After that, it’s back to the doldrums from the 29th of August through the 3rd of September – tiny, weak waves with little energy. Occasional glassy mornings and a bit of offshore wind, but the swell is laughably small at 0.7ft to 1ft. Not worth paddling out for.

So, to sum it up: the only real window to get wet is Wednesday the 19th morning for a clean small long-period groundswell, and the standout is Friday the 28th morning at New Brighton Beach with that 4ft ENE swell and clean offshore wind. The rest, mate, save your wax.

Rusty.

Information about the New Brighton Beach Surf forecast

The above surf forecast table for New Brighton Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at New Brighton Beach can be found by selecting the local surf guide option on the grey menu. Our New Brighton Beach 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 (New Brighton Beach) 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 New Brighton Beach 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.
