The Lowdown
Alright, let’s get this sorted. Sandy Mouth, it’s been a rough patch, and honestly, for the next week and a half, it’s not looking like a whole lot of fun for us paddle surfers. The ocean’s got some juice at times, but the wind’s just been ruining it. We’ve got a long stretch here with nothing worth your time, from Saturday the 12th right through to the 22nd. It’s a solid ten days of onshores and cross-off junk, with the swell getting chopped up into a mess.
Now, there is some serious energy in the water on Sunday the 21st. We’re looking at 8ft of west-northwest swell, with a period of 13 seconds. The combined energy is a massive 2008, which is strong, no two ways about it. But before you get excited, remember the wind is blowing 30 km/h straight onshore from the west-southwest. It’s going to be a chaotic, blown-out mess. This is a time for the kite crew, not for us. At 8ft, that’s also well into the expert-only zone anyway, but with that wind, it’ll be a washing machine.
Then, after that, it finally cleans up. There’s a real change on Wednesday the 23rd. The wind swings around to a light offshore easterly in the morning, and then it goes glassy in the afternoon. This is the one to wait for. The swell drops a bit from the big weekend, but we’re still looking at a solid 6ft in the morning, pushing 6ft by the afternoon, all from the west. The period is a bit short at 7-8 seconds, so it won’t be the most powerful thing, but with that clean, glassy surface, it’ll be the best we’ve seen in a long time. This is your standout window. The water temp is 65°, which is 4° warmer than normal for this time of year. That’s a big deal, it feels like summer out there.
Following that, Thursday the 24th still has clean conditions with a cross-offshore breeze, but the swell drops to 4ft and it’s a bit weaker, with the energy down to 240. It’s a poor cousin to Wednesday, but still rideable. And then, from Friday the 25th onward, it just fades away into tiny, weak surf and the wind turns messy again. The best bet for the whole run is clear: that Wednesday morning and afternoon glass-off is your window.
