The Lowdown

Alright, mate, Rusty here. Let's take a look at the next couple of weeks and see what she's giving us.

The next few days are looking pretty flat, so there's no rush to get wet. The first stretch, from Thursday the 6th through Saturday the 9th, is looking weak and small. The wave energy is low, and the waves are just too small to be worth the effort. It’s clean, but it’s a lot of nothing.

There’s a bit of a pulse on Sunday the 9th, with a 7ft swell, but it's a short-period, wind-blown mess. The wind is putting a real chop on it, so it’s not going to be pretty.

The real standout of this whole window is the morning of Monday the 10th. The wind goes glassy, the swell drops to a clean 2.5ft, but the period is a solid 16 seconds. The water temp is 56.7°, which is just about normal for this time of year. This is your window for some real quality at Manu Bay. That long-period, south-west swell will set up some proper lines.

The surf stays small for the next few days, with Tuesday and Wednesday offering only marginal waves. But then we get another spike on Thursday the 13th. The morning shows an 8ft swell from the west with a 13-second period and a clean, cross-off wind. The energy is strong, and the conditions are looking excellent for the more experienced surfers. The afternoon glass-off is also a treat, with 7ft and that same clean energy. This is a proper day for the better surfers among us.

Friday the 14th is a bit of a messy one with a building wind that will ruin the fun. Then Saturday the 15th is a full-blown write-off. The swell is huge, 13ft, and the wind is howling onshore. It will be a complete stormy mess. That’s not a surf day; that’s a day to stay in bed.

However, the real gem, the one you should be circling on the calendar, is the morning of Sunday the 16th. This is the big one. We're looking at a 16ft groundswell from the west with a 14-second period, and the energy is massive. The wind is forecast to be glassy. This is exceptional, expert-level surf. The size is well over 8ft, so it's strictly for the experienced crew. Manu Bay will be charging. It’s a long way out, so don’t bank on it, but if the wind holds, this will be the session of the month.

The following week is looking more consistent, with chest to head-high waves from the 17th to the 20th. The winds are mostly offshore, and the conditions should be clean. The standout in this run is the morning of Thursday the 20th, with a 4ft swell, a 15-second period, and glassy conditions. Another good call for the fins.

So, the plan is simple: be patient, hit Monday the 10th for a quality session, then save your energy for the 16th and the following week. The potential is there for something special.

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.
