The Lowdown
G’day, Rusty here. Let’s talk about what’s cookin’ at Manu Bay for the next couple of weeks. It’s a bit up and down, but there’s a couple of windows worth paddlin’ out for.
Your first real chance is Tuesday, September 8th. Monday’s a no-go with onshore wind and crappy energy, so forget it. Tuesday morning though, we’ve got a clean 5ft swell from the WSW with a 14-second period and a cross-off breeze from the SSW. Water temp’s 58°, which is normal for this time of year. The combined energy is 914 (moderate wave energy), and for a point break like Manu Bay, that longer-period groundswell is gonna reel off nicely. It’s an advanced-only wave, and crowds are possible, so keep your head on a swivel. Tuesday afternoon goes choppy, so hit it early.
Wednesday the 9th brings a smaller but still clean 4ft swell from the west in the morning, with a light cross-off breeze. Energy’s down to 403, but it’ll be a fun little session. Afternoon onshore kills it.
Now, the big standout. Friday, September 11th—morning session. We’ve got a solid 10ft swell from the WSW with an 18-second period. That’s a very long-period groundswell, and at Manu Bay, that means long, wrapping walls. The cross-off breeze from the south will keep it clean. The combined energy is a massive 5261 (strong wave energy). This is over 8ft, so it’s experts only. Beginners, stay on the beach. The sets will be spaced out but when they come, they’ll be worth the wait. This is your call.
Saturday the 12th and Sunday the 13th have similar size (7ft to 12ft) but the wind goes cross-shore or onshore, so it gets messy. Still big and powerful, but not clean.
From the 14th to the 16th, we get smaller 5ft to 8ft swells but with cross or cross-onshore wind, so it’s choppy and average. Not worth the hassle.
Then from September 17th through the 22nd, it’s a long stretch of poor conditions. The swell stays big—10ft to a huge 13ft on the 20th—but the wind is strong and onshore or cross-onshore, makin’ a mess. The energy is off the charts (9277 on the 20th), but with a strong cross-onshore breeze and a short 11-second period on the 17th, it’s better for kite surfing than paddle surfing. Not for us.
So, in short: the standout is Friday, September 11th morning. Tuesday the 8th morning is your next best bet for cleaner waves at a smaller size.
Keep an eye on the tides, and I’ll see you out there.
Rusty.

Information about the Raglan-Manu Bay Surf forecast
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. Our Raglan-Manu Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Raglan-Manu Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
Raglan-Manu Bay is 42 km (26 miles) from Hamilton. If you plan a holiday in Raglan and West Waikato, look for hotels and other accommodation in Hamilton. Hamilton has rooms for a wide range of budgets as well as car hire and transport links.
