The Lowdown
Hey folks, Rusty here. Let’s break down what St Tugen’s got for us over the next couple of weeks. It’s a bit of a mixed bag, but there’s a real gem of a session if you’ve got patience.
The opening weekend is pretty average. Saturday morning the 12th has some waist-high, 3ft swell rolling in from the W with a short 8-second period, and the wave energy is weak. The wind is glassy though, so it’ll be clean, but there’s no power. Water temp is about 64°F, which is normal for the season. By Saturday afternoon, a cross-on breeze messes it up.
Sunday the 13th picks up a little, with a 5ft W swell and a longer 11-second period, pushing moderate energy. But the wind is onshore in the morning and cross-on in the afternoon, so it stays messy and marginal. Not worth rushing for.
There’s a real lull from Monday the 14th through Thursday the 17th. The swell drops, the winds are mostly onshore or cross-shore, and everything looks flat or poor. A few days of nothing.
Now, here’s the session you’ve been waiting for. Friday morning, September 18th is the clear standout. St Tugen wakes up to a solid 7ft swell from the WNW, with a proper 14-second period – that’s serious groundswell. The combined wave energy is pumping. And the best part? Glassy conditions. Dead calm, no wind. This is for the experienced crew – 7ft is too big for beginners. That clean, lined-up energy is going to be a dream.
The rest of that Friday afternoon gets a cross-on wind, dropping quality. Saturday the 19th and Sunday the 20th are back to poor or marginal.
Into the second week, Monday morning, September 21st has potential. A 6ft swell from the WNW with a 14-second period, strong energy. The wind is a fresh offshore from the NE at 18 mph, so it’ll be blown smooth and clean. Another promising window for the experienced surfer.
Tuesday the 22nd and Wednesday the 23rd mornings also offer clean conditions with smaller, cleaner 4ft and 3ft swells, best for intermediate surfers when the offshore holds. After that, the forecast gets messy again through the end of the period.
For the whole 16-day window, Friday the 18th morning is the absolute best on offer. Monday the 21st morning is a close second. Don’t waste your time on the rest.
Stay stoked,
Rusty.
