Posties Surf Forecast and Surf Report

G’day, it’s Rusty here. We’ve got a solid run of swell ahead for Posties, but it ain’t all smooth sailing. This is an advanced reef break, so keep that in mind. Water temp is around 58°, about normal for this time of year.

We start Friday morning, August 28th, with a powerful 12-ft WSW groundswell, period a long 17 seconds, and the combined energy is pumping at 7298. Wind’s a light cross-on from the west, so it’ll be a bit bumpy with small ripples. Not the cleanest start, but there’s a ton of water moving. Afternoon drops to 12-ft with a 16-second period, energy at 5608, still cross-on. Crowds are sometimes around, so expect some company.

Saturday, August 29th, sees the swell drop to 8-ft from the SW, period 14 seconds, but the wind swings offshore early from the WSW. That’s a big plus—cleaner faces, but energy’s down to 2691. Afternoon stays similar with offshore wind, still a bit raw.

Sunday, August 30th, holds at 8-ft to 10-ft SW, period 13 seconds, but the wind moves cross-on again. Not ideal, but rideable.

The standout of the first week hits Monday, August 31st morning. You’ve got a 10-ft SW groundswell with a period of 15 seconds, energy at 5635, and a light cross-off breeze from the north. That means clean lines—exceptional for expert surfers. That’s your best bet early on. The afternoon fades with a cross-on wind nudging 8-ft.

Tuesday, September 1st, brings a fresh breeze from the NNW at 19 mph, cross-off again, with 10-ft SW swell, period 16 seconds. Energy’s moderate at 3754, but that wind makes paddling out a chore. Afternoon gets messy with cross-shore wind.

By Wednesday and Thursday, things get wild. Swell builds to 13-ft and 15-ft, then hits 18-ft on Thursday afternoon with a strong breeze from the WNW at 25 mph, energy screaming 10517 to 14140. This is too big for all but the most experienced, and the wind is making it a lumpy, cross-chop mess. Friday, September 4th, is even bigger—20-ft SW, energy 16394—and the swell’s too big for this break. I’d call it a kite-surfing day, not a paddle day.

The second week settles a bit. Monday, September 7th morning, is another gem: 7-ft SW groundswell, 11-second period, with a light offshore from the ENE. Clean, excellent conditions for experienced surfers. Energy’s mild at 1937, but quality will be there. Thursday, September 10th morning, follows a similar pattern: 6-ft SW, period 16 seconds, light cross-off from the north, energy 1924, clean faces.

Watch out for Friday, September 11th morning—a 16-ft SW groundswell, period 18 seconds, energy at 16749, with a cross-off wind from the north. That’s a massive, long-period swell, and it’s too big for this break again. Expert-only territory, if anyone’s mad enough.

Overall, the best on offer is Monday, August 31st morning for that combo of size, energy, and clean conditions. The second-week call is Monday, September 7th morning—smaller but cleaner, a nice change from the chaos.

Rusty.
