The Lowdown

G’day, Rusty here. Let’s break down what’s brewing for the next couple of weeks at Manu Bay.

The main spot is Manu Bay (Raglan-Manu-Bay), and we’ve got a solid run of groundswell coming in from the WSW, but the wind’s going to be the deciding factor on whether it’s a go or a no. Water temp is 58°F, which is totally normal for this time of year – no surprises there.

Right off the bat, it’s not good. Sunday the 13th has a 12 ft WSW swell with 30 km/h cross-winds and lumpy chop – a total mess. That strong energy is wasted. Monday and Tuesday morning are still messy with cross-shore winds and a cross-chop, even though the swell sits around 7 ft to 8 ft.

The first real standout is Tuesday morning the 15th. Swell drops to a clean 6 ft from the WSW, period a solid 14 seconds, and the wind goes glassy from the ENE at just 5 km/h. That’s going to be smooth, lined-up waves at Manu Bay – a real window of opportunity.

After that, the swell drops off. Wednesday and Thursday see the waves below 5 ft and the wind turns cross-onshore, choppy, and not worth your time.

Friday the 18th brings a new 6 ft to 7 ft WSW groundswell, but it’s cross-onshore in the morning. The afternoon is a bit better but still not clean. Saturday the 19th has a 8 ft swell again but with 20 km/h cross-winds and showers, so it’s lumpy.

The next standout window is Monday morning the 21st. We’ve got an 8 ft WSW groundswell, period 14 seconds, and light onshore wind from the NW at just 5 km/h. It’s rideable, and the energy is strong.

From the 22nd to the 24th, we get steady 7 ft to 8 ft swell, mostly cross-shore or cross-off winds. The 22nd afternoon and 23rd morning look clean with cross-off breezes.

The 25th and 26th get rough again with strong 35 km/h winds and lumpy, poor surf.

Then, Sunday morning the 27th is another beauty. A 5 ft WSW groundswell, 14-second period, and a light southerly at 5 km/h blowing cross-off. The report says “clean,” and this is looking like the pick of the whole run for smooth, crowd-friendly waves.

If I had to call it: Tuesday the 15th for the glassy 6 ft waves, and Sunday the 27th for the light offshore clean lines on a 5 ft swell. Both are prime Manu Bay moments.

Remember, the longer-range forecast is promising but not locked in. The near-term stuff is rough, so be patient.

Stay stoked, check the tide, and I’ll see you out there.

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.
