The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Sandy Mouth over the next couple of weeks.
First up, I gotta be straight with you: it's a tough run. The data shows a long stretch of poor surf conditions, with the swell tiny and the wind all over the place. The first real recommendation doesn't pop up, so we're looking at a gap of several days where the surf just isn't offering anything worthwhile. The combined wave energy is weak, with values mostly in the double digits (27) to start, and the water is sitting at 66°F which is much warmer than normal for this time of year – a bit of a surprise.
We're in for a long wait. The tiny swell and poor conditions just keep rolling through the end of August and into the first week of September. It's a blank run, and honestly, for this area, that's not unusual. The consistency is there, but the quality is not.
Then, there's a glimmer on Saturday the 29th of August. The swell jumps up to 8ft from the WNW, but hold your horses. The wind is howling onshore from the W at 19 mph, making it a mess. The combined energy shoots up to 661, but with that wind, it's not a paddle session – it's a kite-surfing show. It's too big for beginners and only for the experts who don't mind a battle.
The only other notable spike comes on Monday the 31st of August, with a 7ft NW swell and a combined energy of 385. But again, the wind is cross-onshore from the NW, making it choppy. It's a little better than the weekend, but still not what you'd call a standout.
Honestly, there's nothing here that qualifies as a true standout. The forecast is consistent, but consistently poor. The long-range stuff into the first week of September is even less promising, with the wind staying strong and messy. The best advice I can give is to keep an eye on the charts because it tends not to stay this poor for long, but right now, I'd leave the board in the car.
Rusty.
