Southport Main Beach Surf Forecast and Surf Report

G'day, it's Rusty here. Alright, look, I'm not gonna sugarcoat it – the next week and a half is a real struggle for Southport Main Beach. We've got a solid 16-day window in front of us, but the surf is basically on life support for the first week or so. A lot of small, weak energy with moderate onshore or cross-shore winds making a mess of things. There's a big gap of poor conditions from now (9 August) all the way through to around the 22nd of August, which is a long, dry spell.

Let's break it down. From Sunday the 9th right through the week, the swell is tiny – mostly 2 ft to 3 ft – and it's coming from the East with a short, weak period of 9 seconds. The combined swell energy is weak, bouncing between 75 and 191. The wind is all over the shop, mostly cross or cross-onshore, so you're looking at bumpy, choppy lines. Even when we get a glassy morning on Thursday the 13th, the swell is only 2 ft, which is barely a ripple. Not worth paddling out for.

We finally see a bit of size start to build around the 16th of August with 5 ft, but the period drops to 7 seconds and the combined energy gets up to 263, which is now moderate. The problem is the cross-shore wind is still making it lumpy and the forecast calls it "poor surf conditions". This pattern of increasing swell but terrible wind continues right through to the 21st. The waves get bigger, up to 7 ft on the 22nd of August with a better 10-second period and moderate wave energy (855-921), but the wind is still cross-onshore or cross, so it's choppy and messy again. It's more of a kite surfing setup than a paddle surfing one.

Now, here's the good news. The standout period kicks off on Sunday the 23rd of August. The wind finally swings offshore from the West, blowing at 15 to 19 mph. We get a clean 5 ft to 5 ft East swell with a 9-second period and combined energy in the moderate range (372-440). The forecast even says "expect good surf conditions". This is the pick of the entire run. It's a classic winter offshore day that'll have the banks groomed and offering some fun, rippable walls. The water temp is about average for this time of year at 69°F.

The best of the best? That's Monday the 24th of August. The swell drops to a more manageable 4 ft to 4 ft, but the period stretches out to 11 seconds, so there's some nice groundswell energy in the water. Combined energy is still moderate at 403 to 418. With a light offshore or cross-off wind, it’ll be glassy and clean. Southport Main Beach can get crowded, and this kind of quality on offer will definitely have a few locals out, but with clean lines and a solid swell direction matching the optimum (ESE), it's the day to be in the water.

So, to sum it up: endure the first two weeks of chop and small waves, and your reward is a couple of absolute crackers on the 23rd and the 24th of August. Long-range is always a bit more of a gamble, but the combination of offshore wind and building swell has me optimistic. Stay patient.

Rusty.
