The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ at St Tugen over the next couple of weeks.
The short story is that we’re in for a long, long quiet spell. The surf is just not present for a solid week. The first real chance of a wave is on the morning of the 25th, with a tiny 2 ft of west swell, but the combined energy is weak at only 76. The wind is light and offshore from the NE, so it’ll look clean, but honestly, you’ll be battling for knee-high dribbles. It’s more of a longboard or a paddle than a proper surf.
We then have another run of poor conditions until the very end of the month. The first standout that gets me talking is the morning of Sunday, the 30th. We get a cleaner 5 ft WNW swell with a period of 9 seconds, delivering a moderate energy reading of 314. The wind goes light and cross-off from the NNW, so it’ll be shaped and clean. This is the first time in a while the place might actually offer a decent wave.
But the real firecracker in this forecast is Monday morning, the 31st of August. That’s the one. We’re looking at a solid 7 ft swell from the west, and the combined energy jumps to 912 – that’s serious power. The wind is light, offshore from the ENE. It’ll be glassy. This is the best session on offer by a long shot. It’s a proper groundswell at 8 seconds, which isn't a super long period, but the size and the clean offshore wind will make St Tugen really throw its shoulders. It's a solid intermediate wave at this size – a bit much for beginners.
After that, on Tuesday the 1st of September, the swell jumps to 8 ft from the SW with huge energy (1106). That’s expert territory, and the cross-shore wind will mean it’s a bit ragged by afternoon. The morning might still hold some cleanish lines if you’re brave.
Overall, don’t bother paddling out until the morning of the 31st. That’s the one to circle on the calendar. It won't be perfect, but it’ll be the best we get. The earlier stuff on the 30th is a consolation prize.
Stay patient, keep the wettie dry till then.
Rusty.
