The Lowdown
Alright crew, Rusty here. Let's talk turkey.
The first real surf showing up is on Friday, September 11th. There’s a big gap of nothing before that, so don't rush down.
Friday the 11th in the morning is your clear winner. Manu Bay is seeing a solid 10-foot groundswell from the WSW with an 18-second period – that's long-period, proper energy. The wind is light offshore from the south at just 3 mph, keeping the surface clean as a whistle. The combined energy is strong at 5328. This is a day for the experienced lot – the size is serious. Crowds are possible here, but if you’re on it, you’ll be in for some of the best waves of the run.
Friday afternoon turns sour as the wind picks up onshore, getting messy. Saturday and Sunday are absolute write-offs with strong, lumpy cross-shore winds and even bigger swell, up to 13 feet. A total blown-out mess.
Monday the 14th is a drop to about 8 feet, but still with a touch of chop. It’s rideable if you're keen. Tuesday the 15th drops to around 6 feet and gets choppy again.
Now, Thursday the 17th of September morning is another good one. Swell is back up to 8 feet from the WSW with a 14-second period. The wind is light offshore from the south-southwest at 6 mph, giving clean waves. Moderate-strong energy at 2525.
The rest of the second week is a battle with strong winds from Friday the 18th onward. Friday the 18th has near-gale force winds, and the following days into the 20th and 21st are messy, with lumpy cross-shore winds and 6 to 11 foot swell. Not good for paddling.
By the 25th and 26th of September, things finally clean up a little with lighter winds and smaller, more manageable waves in the 4 to 5 foot range. It’s small but clean on the 26th morning.
Stick to the 11th and 17th mornings if you want the best of it. Everything else is a fight against the wind.
Rusty out.

The above surf forecast table for Raglan-Manu Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Raglan-Manu Bay can be found by selecting the local surf guide option on the grey menu.

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.
