The Lowdown
G’day, Rusty here. Let’s break it down for Raglan – Manu Bay over the next couple weeks. The water temp is 57°, right on average for the season, so nothing weird there.
Thursday, September 3rd starts off with 5 ft swell from the WSW, 15-second period, but a cross-on wind from the WNW at 9 mph messes it up. Energy is moderate (1088). Not worth it. Friday the 4th is a total loss – 35 mph onshore winds and bumpy 8 ft – 10 ft swell.
Saturday the 5th and Sunday the 6th have solid 8 ft – 10 ft swell, but winds are cross or cross-on, so choppy. High energy readings (over 3000) don’t help the quality.
Monday, September 7th starts to turn. Morning has 8 ft swell, 16-second groundswell, and light 6 mph wind from the W. Slight chop, but it’s workable. Afternoon drops to 8 ft swell with near-calm 3 mph winds – almost glassy. This is the pick of the first week.
Tuesday morning, September 8th, is the standout. You’ve got 8 ft swell from the W, 13-second period, and glassy conditions from the WNW at 3 mph. Perfect for experienced surfers. Crowds are a possibility, so get in early.
Wednesday the 9th through Saturday the 12th is mostly poor or messy. Thursday the 10th has 10 ft swell but 25 mph winds; by Friday the 11th, swell hits 13 ft – 15 ft with 28 mph winds and energy over 11000 – that’s a kite-fest, not for paddlers.
Sunday morning, September 13th, you get another clean one: glassy from the SSE at 3 mph, 8 ft swell, 15-second period. Strong energy (2686). Expert territory. Crowds likely.
The week of September 14th to 16th is poor – strong winds, messy 7 ft – 13 ft swell. Skip it.
Thursday morning, September 17th, brings clean cross-off winds from the SSW at 9 mph. Swell is 6 ft, 11-second period. Excellent for experienced surfers. Energy is moderate (2027).
Friday morning, September 18th, wraps it up with glassy ENE winds at 3 mph, 6 ft swell, 15-second period. Good clean waves.
The gap between good sessions runs from the 9th to the 12th, then again from the 14th to the 16th. Your two best bets: Tuesday morning, September 8th and Sunday morning, September 13th.
Rusty.

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.
