The Lowdown
G’day, Rusty here. We’ve got a 16-day stretch that’s got its ups and downs, but there’s some absolute smoking waves if you play it smart. The main event is Raglan-Manu Bay (New Zealand), a classic point break that knows how to handle a solid swell. Water temp is about 57°F, right on average for the season, so nothing weird going on.
We start Monday, 17 August morning, and it’s game on. Solid 7ft WSW swell with a 15-second period – that’s real groundswell, packing a punch. Combined energy is massive at 2055 (very strong). Wind is light S at 15 mph, cross-off, meaning clean, peeling waves for the experienced crew. This is expert territory; that size is too much for beginners. A standout right out of the gate.
Monday afternoon picks up some wind – 25 mph from the SSW, still cross-off – and the swell holds at 7ft. Still quality, but the morning is prime.
Tuesday, 18 August morning eases to 5ft from the WSW, 14-second period, energy at 874 (moderate). Wind is light S at 10 mph, cross-off. Clean, fun lines – more friendly for a wider range of surfers. Manu Bay is consistent and crowds are only sometimes, so you’ll have room.
Wednesday, 19 August morning has 25 mph wind from the S, swell at 5ft, 13-second period, energy at 1087 (moderate). Still clean, but the afternoon looks better with the swell bumping to 6ft and period stretching to 16 seconds, energy at 1550 (strong). Winds ease to 15 mph from the SSW. Worth it.
Thursday, 20 August morning is the glassy sleeper. Swell is 5ft from the WSW, 14 seconds, energy at 956 (moderate), but wind is SE at just 3 mph, glassy. Expect clean, nearly perfect surf.
Friday, 21 August through Saturday, 22 August gets messy. Onshore winds from the WNW chop things up, swell drops. Poor conditions.
Sunday, 23 August morning sees a new pulse – 8ft from the W, but only 8-second period – short-period windswell, lumpy with strong cross-on winds. Not worth it.
The big second-week standout is Monday, 24 August morning. That’s the one. Swell hits 10ft from the WSW, 16-second period, combined energy at 4151 (very strong). Wind is light SW at 10 mph, cross-shore. Massive groundswell – expert-only, but for those who can handle it, it’s a dream. The afternoon stays similar at 10ft, 15-second period.
Tuesday, 25 August has 8ft swell but onshore winds from the NNW, poor.
From Wednesday, 26 August to Friday, 28 August, it’s mostly onshore, rain, and choppy. A lull.
Saturday, 29 August morning offers a clean but short-period pulse – 6ft from the WSW, only 8 seconds, but light SSE cross-off winds. Fun if you’re desperate.
Sunday, 30 August morning is another gem: 4ft swell, but a 16-second groundswell with glassy offshore wind from the NE at 3 mph. Energy at 792 (moderate). That long period on a point means groomed, lined-up waves. Very clean.
Monday, 31 August and Tuesday, 1 September finish with small, clean days – 3-3ft, 16-second period, light offshore or glassy winds. Good for a longboard.
Best bets: Monday, 17 August morning, Thursday, 20 August morning for glass, and Monday, 24 August morning for the big stuff. The long-range call on Sunday, 30 August is promising but less certain – keep checking the wind.
Stay stoked.

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.
