The Lowdown

Alright, grab your wettie. Rusty here, and I’ve been staring at the charts for the next couple of weeks. It’s a bit of a mixed bag, but there are a few windows you’re gonna wanna be wide awake for.

The big story is that Raglan-Manu Bay is going to see a whole heap of energy, but most of it is going to be blown out. The first week is a write-off for the most part. We’ve got a big, powerful groundswell rolling in on the 5th and 6th, packing some serious punch with combined energy readings of 3434 and 3720, but the wind is a mess. That early swell on Saturday the 5th is 9.8 ft from the WSW, but it’s cross-onshore and choppy. By Sunday morning it’s dropping slightly to 8.2 ft from the W, but it’s onshore again. It’s just not happening.

Then we get a gap of really sloppy conditions through the middle of the first week. It’s not until Tuesday the 8th that things start to look interesting. That morning the wind drops to glassy. Zero wind. The swell is still a solid 6.9 ft from the west, with a long period of 12 seconds and moderate wave energy (1249). This is your standout for the whole run. It’s going to be clean, powerful, and long. The water temp here is 57.2°, which is about 0.5° off normal for the time of year, so pretty average for the water temp. But the tide will be a factor with a swell this size on a point. This is advanced, long-period wave energy, so the paddle out will be easier between sets.

Wednesday morning the 9th is glassy again but the swell has dropped right off to 3.6 ft with light energy (397). It’ll be clean but small.

After that, it gets ugly again. By the 10th and 11th, we’ve got another massive pulse. On Friday the 11th, the combined energy hits a massive 9700 and 11924, with a 13.1 ft to 14.8 ft swell. But the wind is screaming at 25 mph, leaving a messy cross-chop. That is pure kite surf territory, not a paddle session.

Conditions slowly start to improve into the second week. By Monday the 14th, the wind drops back to a gentle cross-shore, but the swell is still a chunky 9.8 ft with strong energy (3912). It’s still marginal though.

The real promise for a second look is towards the very end. On Friday the 18th of September, we’ve got an 8.2 ft west swell with a 13-second period and a light cross-shore wind. The combined energy is 2235 and the score is decent. Saturday the 19th is smaller at 5.2 ft with a 10-second period, but it’s a light cross-shore again. And then Sunday the 20th gives us a 3.3 ft to 4.3 ft WSW groundswell, but with a cross-offshore breeze. It’s clean, but small.

Best bet? Get out there Tuesday morning the 8th. That’s the one.

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.
