The Lowdown
Alright, Rusty here again, let’s talk about Port Waikato-Sunset Beach in feet and miles an hour.
Your absolute best shot is Thursday morning, August 20th. The wind is glassy – a light offshore from the ESE at just 3 mph. The swell is a solid 7ft from the SW, with a long 14-second period. That’s proper groundswell with some real grunt. The water temp is about 57°, which is normal for the season. The combined energy is strong at 1761, so you’ll feel the power. This is for experienced surfers only – that size on an exposed beach will have some punch.
After that, things get messy. From Thursday afternoon through the weekend, the wind goes onshore or cross-onshore, and the surf quality tanks. Friday and Saturday are choppy, and Sunday (August 23rd) is just poor.
Monday (August 24th) is a monster – 13ft swell with a 13-second period. Combined energy hits 4975. That’s expert-only, and honestly, it’s probably too big and raw for this beach. Not the day for a paddle.
The next decent window pops up on Friday morning, August 28th. The wind turns clean and cross-off from the NE, dropping the swell to a more manageable 6ft from the WSW. The period is still a long 14 seconds, so there’s shape. Crowds can be a thing here sometimes. It’s not the gem of that first Thursday, but it’s the best you’ll get in that second week.
Saturday and Sunday (29th-30th) hang onto clean cross-off winds, but the swell drops to around 4ft. Good for a longboard or a fun shape, but nothing special.
Into early September, the wind is unreliable – onshore again, and by the 3rd and 4th, it’s just choppy or blown out.
So, crown your Thursday morning, August 20th. That’s the one to chase. Clean, glassy, solid SW groundswell. After that, Friday the 28th is your backup. The rest is either too messy or too quiet.
Rusty.
