The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu.
The next sixteen days are a real mixed bag at Manu Bay. It’s a classic point break that lines up best with a solid SW groundswell, and there’s plenty of size on the way, but the wind is going to be the main character here—and not always in a good way. The water temp is sitting at 58°, right around where you’d expect for the time of year, no surprises there.
The standout window is looking like Thursday the 24th of September. That morning, it’s all coming together: a massive 16ft swell from the WSW with a period of 14 seconds, and glassy conditions with the wind swinging out of the east at just 3 mph. The combined energy reading is a strong 8287. This is big, powerful, long-period groundswell—absolutely perfect for a point break like Manu Bay, where it will groom into proper walls. That said, at over 8ft, this one is strictly for the experienced crew. Crowds are sometimes an issue here, so get in early.
Earlier in the week, Friday the 11th of September is worth a look. The morning session is clean with a 10ft WSW swell, 18-second period, and a light 6 mph cross-off breeze from the south. That’s a lot of energy (5328) and that very long period will produce some beautiful, long-running lines down the point. Again, advanced surfers only at this size.
The week after, look at Thursday the 17th of September. The afternoon lights up with a 8ft WSW groundswell, a 14-second period, and light cross-off winds from the SSW at 6 mph. Clean conditions and solid energy (2665). Still a bit too big for beginners, but a good option for the experienced.
There’s a long gap of poor conditions between Saturday the 12th and Wednesday the 16th where the wind just blows too hard from the west and southwest, making things lumpy and messy. Not much to get excited about there.
From the 22nd onward, we see some serious size returning, but the wind keeps it from being clean until that Thursday. The 25th and 26th of September still have decent leftover swell in the 10ft to 6ft range, with glassy mornings, so those are worth keeping in the back of your mind for a quieter, cleaner session.
So, the pick of the pack is Thursday the 24th of September—if you’re an expert and you can handle the size, that’s the day to be on it.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Raglan-Manu Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
