Southport Main Beach Surf Forecast and Surf Report

Right off the bat, I’m going to be straight with you—if you’re looking for a proper surf session, you’re going to be waiting a while. We’ve got a long stretch of nothing, then a couple of days that might get the heart going, but honestly, the first week and a half is a write-off.

Starting this Tuesday morning (15 September), Southport Main Beach is looking flat and messy. Tiny 0.5m of wind slop out of the E with a weak 6-second period and barely any energy in the water (30). A northerly breeze isn't helping, and it's just cross-shore. It's a beginner’s spot, and even they’d be bored. The afternoon doesn’t get any better—25 km/h NNE winds and the same weak surf.

Wednesday (16 September) is more of the same until the afternoon when a bit of a pulse shows up—1.9m from the SE with an 8-second period. The energy picks up to 427, but it’s doing it under a strong 40 km/h SSE wind. That’s cross-onshore and messy. Not worth the paddle out.

Now Thursday (17 September) morning is where things start to get interesting, but it comes with a warning. We’ve got a solid 3.0m of SSE swell, 10-second period, and the energy is up there (1997). That’s proper size, but the wind is still fresh and cross-shore at 30 km/h. The wave comment says marginal, and I’d agree—it’s lumpy and cross-choppy. This is over the 2.5m mark, so it's strictly for the experienced crew. Beginners, stay on the sand. The afternoon drops back to 1.6m and the energy eases, but it’s still not clean.

Friday (18 September) is a tease. The swell drops right back to 0.9m, though there’s a light 10 km/h SE wind. It’s cross-on, but pretty weak. There’s some energy (120), but it’s just not enough to get excited about.

The weekend is bleak. Saturday (19 September) morning has clean conditions with a light offshore-ish cross-off from the NNW, but the surf is only 0.6m at 8 seconds. Energy is down at 61. You’d be scratching for anything. Sunday is even worse—dropping to 0.3m with no push at all.

Then we hit a dead zone. Monday (21 September) through to Friday (25 September) is basically flat, with swell hovering around 0.1m to 1.3m, but the period is short (4-7 seconds) and it’s almost always onshore. There’s no hope in that stretch. The wind is mostly moderate to fresh, and the rain shows up on the 23rd and 25th. It’s a blank run, and it’s normal for this stretch to just go quiet.

Now, here’s where it might get a little more interesting, but it's still a gamble. Saturday (26 September) morning brings 1.5m of E swell, 8-second period, with a gentle cross-onshore ENE breeze. Energy is at 304. Still “poor surf conditions” on the report, but it’s at least a bit of size. The afternoon is similar, and it’s still not clean.

Sunday (27 September) is a real mixed bag. Morning has rain showers, 1.4m at 8 seconds, and a cross-shore NNE breeze. The report calls it marginal—could be a case of questionable tide. The afternoon pushes up to 1.8m from the ENE, but the energy jumps to 761 and the onshore wind picks up, making it choppy. It’s still poor.

Monday (28 September) has rain showers and a moderate cross-onshore wind, with 1.6m and 1.5m of E swell. Not great, just messy.

Then we get to Tuesday (29 September) morning—this is the one standout in the whole run. There’s 1.2m of ENE swell, 9-second period, with a gentle cross-shore wind. The energy is moderate (225), and the report actually says “marginal” but the wind is light. The water is still 21.1°, which is about normal for this time of year—nothing weird there. The morning looks like the cleanest window, but it’s still only 1.2m. The afternoon turns rainy and cross-on, so grab it early if you can.

Wednesday (30 September) morning has rain showers, a cross-off wind from the NNW, and 1.1m of ENE swell at 9 seconds. Energy is 202, and it says “marginal” but with clean conditions. That might be your second-best chance, but it’s still small.

In the end, if I had to pick the best of a bad lot, I’d point at Thursday morning (17 September) for the sheer size—3.0m will get the experts out, but the wind is going to make it ugly. And Tuesday morning (29 September) for the cleanest conditions, even if it’s small. Everything else is either flat, wind-blown, or just not worth the effort.

If you’re a kite surfer, the 16th and 23rd might look more appealing than paddle surfing—strong winds, choppy seas, and a beach setup. But for a
