The Lowdown
Alright, Rusty here again, looking at the same charts for Southport Main Beach but in the old measurements. Honestly, it’s a rough start, and the whole 16 days doesn’t look like much fun. The water temp is about 70°, normal for the season.
From Monday the 14th, we got zilch. Tiny little wind swells, nothing but cross-onshore junk. Swell’s around 2ft, with a short, weak 6-second period. The energy is only 38 (weak). This flat, messy weather hangs around for a long time. From Monday the 14th all the way through Tuesday morning the 22nd, it’s a total blank. No real waves.
Finally, on Wednesday the 23rd morning, we get a bump. Swell hits about 5ft from the ESE, period still short at 7 seconds. Energy is 292 (moderate). Wind is a light cross-onshore, so it’s okay but not clean. Still, it’s the first proper size we’ve seen. Thursday the 24th and Friday the 25th keep that size, around 5ft to 6ft, but the wind stays onshore. Friday morning’s energy is 559 (strong), but it’s messy.
The one day to save the trip is Saturday the 26th. Morning looks best. Swell hits 7ft from the ENE, with a 9-second period. That’s a solid groundswell. Energy is massive at 1229 (very strong). Wind is light offshore from the ENE, so glassy clean conditions. The catch? 7ft is big, really for experts only on this exposed beach. And with that period, it could close out hard. But if you’re skilled, Saturday morning is your one standout. Expect a crowd.
After that, Sunday the 27th holds some 5ft to 6ft swell, but the wind goes bad again. Then Monday the 28th and Tuesday the 29th fade back to 3ft to 4ft with onshore junk. A poor finish.
So, wait for Saturday the 26th. That’s your only real chance. Otherwise, the 16-day outlook is pretty bleak.
Rusty.
