The Lowdown
G’day, Rusty here. We’ve got a solid run of swell heading into Raglan’s Manu Bay over the next week or so. The standout window is the weekend, with clean, powerful groundswell and light winds lining up for some epic sessions. Things taper off after that, so don’t sleep on the good days.
The first proper call is Thursday afternoon, 13th August. Swell hits 4ft from the WSW, with a period of 13 seconds. The combined energy is moderate (871) and winds are light cross-off from the east at 12 mph. It’ll be clean and fun, but not the biggest.
Friday, 14th August morning is even better. Swell at 4ft, WSW direction, 16-second period—that’s a nice groundswell starting to fill in. Energy is moderate (834) with light ESE winds at 3 mph. Clean conditions and a long wall of a wave for the advanced crew.
Now for the true standout: Saturday morning, 15th August. Swell jumps to 6ft from the WSW, period 17 seconds, with very strong energy (1889). Winds are light SSW at 6 mph, cross-off and clean. This is excellent surf for experienced surfers. It’s big enough to be challenging—over 5ft so not for beginners—and that long-period groundswell will stack up beautifully for the point. Expect some of the best waves of the run.
Sunday, 16th August is also pumping. Morning sees 6ft swell, 16-second period, very strong energy (2186), and offshore SE winds at 6 mph. Glassy, lined-up sets. Afternoon stays good at 7ft with clean cross-off winds. Both sessions are excellent for experienced surfers.
Monday, 17th August holds at 6ft in the morning, but winds swing southerly cross-off, still clean. Energy drops a bit (1580) but remains moderate-strong. Afternoon gets a slight cross-chop.
Tuesday morning, 18th August offers a glassy, clean session with 5ft swell from the WSW, 14-second period, and zero wind. That’s a rare, perfect window for a relaxed session with quality waves.
Wednesday and Thursday, 19th and 20th August, keep the swell around 5 to 6ft, with clean conditions. Good vibes but nothing matching the weekend peak.
From Friday, 21st August onward, the energy drops. Swell slips under 4ft, periods shorten to 14 seconds or less, and winds become less favourable. By Sunday, 23rd August and into the next week, we’re looking at small, weak surf with poor conditions. Combined energy falls below 300, and winds are onshore or cross-onshore. Not worth paddling out.
Water temp sits at 57°F, which is about average for this time of year, with a slight negative anomaly of -0.5°F. Nothing to worry about.
Bottom line: Saturday morning 15th August is the pick—solid 6ft WSW groundswell, 17-second period, light cross-off winds, and clean. Sunday 16th is right there with it. Don’t miss it.
