The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the menu for the next couple of weeks at St Tugen.
Right off the bat, I gotta be straight with you – the first week and a half is a write-off. We’re looking at a solid gap from now until about the morning of Wednesday, September 2nd. There’s just nothing worth paddling out for. The wind is all over the place, mostly onshore or cross, and the swell is either small, weak, or just plain messy. That WNW swell that shows up on the 20th and 21st is around 5ft to 7ft, but the cross-onshore wind is ruining it completely. The water temp is sitting at 64°F, which is about 1°F cooler than normal – nothing to write home about, just your average late summer feel.
So, we wait. The real window opens up on Wednesday morning, September 2nd. That’s where the first bit of hope kicks in. It’s not a world-beater, but it’s clean. We’ve got a 5ft swell from the SW with a 8-second period, which is short-period wind swell, but the wind is light and cross-off from the NNW. The combined energy is moderate (272). It’s surfable and clean, and after all that crud, I’ll take it.
But the standout – the one you want to circle on the calendar – is Friday morning, September 4th. This is the best we’ve got. The forecast is showing a clean 6ft swell from the NW, with a 8-second period and a light offshore breeze from the ENE. The combined energy jumps up to 759 (strong), and the conditions are expected to be very good. That’s the one. The swell direction (NW) is a bit off the optimum WSW, but with that offshore wind and clean conditions, it’s the pick of the bunch. It’s not huge, but it’s solid and clean. The afternoon might get a bit lumpy with a cross-wind, so get on it early.
The rest of the second week is a mixed bag. Thursday the 3rd has a 6ft swell from the W, but the period is short and the wind is cross-off – it’s marginal. The following weekend and into the next week, the size jumps up again (10ft to 12ft on the 28th and 29th), but the wind is howling onshore, making it a mess. That’s a pass for paddling, but if you’re into kiting, that setup might be more your speed.
In short, the surf is dead for over a week, then we get a few clean windows. The Friday morning session on the 4th is your best bet. Don’t get your hopes up for the rest.
Rusty.
