The Lowdown
Alright, Rusty here, looking at the 16-day forecast for the Raglan coast. You’ll want to be patient for the first week because the wind is going to make a mess of things. No point getting wet in lumpy, cross-shore junk.
The first real shot is on Tuesday the 8th. The standout is Manu Bay (Raglan-Manu-Bay). Tuesday morning brings a 2.5m west swell, 13-second period, with a combined energy of 2537 – that’s moderate-to-strong. The wind is glassy, dead calm. It’s a point break, and that long-period swell will wrap in and give you long, clean walls. It’s an advanced wave, so you need to know what you’re doing. Water temp is about 57°, which is normal for the season.
After that, we get a few cleaner days, but the next real standout is Sunday the 13th. The morning has a 1.2m WSW swell, light cross-offshore wind. The afternoon is the real beauty: a 1.0m west swell with a very long 21-second period. Glassy conditions, calm wind. The energy is moderate at 1536. For a point break, that’s a classic setup. Expect long, peeling waves. Crowds are sometimes a thing here, but it’s a big wave.
The period around the 10th and 11th gets small and messy, but the 12th has a clean 1.5m session with glassy conditions, and the 15th has another glassy afternoon with a 1.3m 15-second swell. The second week is a bit more hit-and-miss, but the 13th is the one to circle. Stick with the glassy windows and you’ll score.

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.
