The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Alright, let's be straight with you. The next week or so is looking pretty average for the most part. We’ve got a long stretch of lumpy, cross-shore wind and messy conditions that just aren't doing the waves any favours. The early part of the forecast is a write-off for a decent paddle. There’s a real gap here from the start with no real quality surf on offer.
Things start to get interesting around Sunday, September 13th. The wind finally swings around to a clean cross-offshore breeze, which is a massive plus. This is the first real window of clean surf. The swell is coming from the east at about 6ft, but it's a short period windswell. The energy is moderate (620). It’s not going to be a world-beater, but after that long stretch of chop, it’ll feel like a gift. The water temperature is sitting at a very normal 80.8°F.
Then, on Monday, September 14th, we get a proper offshore wind. The swell is a bit bigger from the east-northeast at 7.6ft, still with a short period. The energy is solid (1433). The wind is light and blowing straight offshore, which will make the lineup clean. This is a definite standout for the period.
The real standout, though, is shaping up for Tuesday, September 15th. It's a morning session all the way. We’re looking at a 3.6ft groundswell from the southwest with a very long 21-second period. The energy is strong (1486). The wind is forecast to be glassy. Absolutely zero wind. This is a recipe for perfect, long lines. The break is a reef, so that long period swell will wrap in beautifully. It's a spot for experienced surfers, especially with that long period, but the conditions are described as excellent for experienced surfers. This is the one to circle on the calendar. It’s still a fair way out, so keep an eye on it, but it’s the most promising day on offer.
After that, the swell backs off a bit, and the cross-shore winds return, so the quality drops off for the rest of the outlook.
