The Lowdown
G’day, I’m Rusty. Let me tell you straight up – we’ve got some real quality on the table for Raglan-Manu Bay over the next couple of weeks, but you’ll need to pick your moments. The water temp is sitting at about 57°, which is pretty much spot-on average for this time of year, so nothing crazy there.
The first real standout is Thursday morning, the 20th of August. It’s dead glassy with the wind swinging around to the ESE at 0 mph, and we’ve got a clean 5 ft swell rolling in from the WSW at 14 seconds. That’s a proper groundswell, and on a point break like Manu Bay, it’s gonna groom up nicely – long, lined-up walls. The combined energy is sitting at 1076 (moderate wave energy), so there’s enough push to get you moving without it being a handful. This is the pick of the first week.
After that, the wind gets a bit messy through Friday and Saturday – cross-on breezes and choppy conditions. Sunday the 23rd gets a big pulse of 8 ft from the west, but it’s onshore and sloppy with a short 9-second period, not worth paddling out for. By Monday the 24th, we see energy jump right up to 1790, but the wind is still cross or cross-on, so the quality isn’t there yet.
Now, if you can wait, the absolute standout session in the entire 16-day window lands on Tuesday afternoon, the 1st of September. We’re talking a clean 6 ft swell from the west at 13 seconds, light SSW breezes giving you a cross-off trim, and the combined energy cranks to 2193 – that’s strong wave energy, proper grunt. Conditions rated as excellent for experienced surfers. Manu Bay will be rifling down the point. This one’s a long-range call, so keep an eye on it – forecast might shift, but if it holds, it’s the session to circle.
The following morning, Wednesday the 2nd of September, also looks solid – 8 ft from the WNW with clean cross-off winds, though at that size it’s definitely for the experienced crew only. That one’s got 1898 on the energy scale.
Late in the run, Sunday the 30th of August and Monday the 31st see a drop in size to around 2 ft to 3 ft, but with clean offshore ESE winds and a long 18-second period on the Sunday, it’ll be glassy and fun for a longer board – nothing epic, but a nice way to finish the month.
Rusty.
