The Lowdown
Right then, let’s have a look at what’s coming up for St Tugen. Honestly, the next couple of weeks are a bit of a mixed bag, and we’ve got a long stretch of nothing much to start with. The water's sitting at about 66°F, which is pretty normal for this time of year, so don't expect any surprises on that front.
The first real chance of a wave doesn't come around until Friday morning, the 21st of August. That's a solid few days of waiting. But when it does arrive, it looks like a decent little window. Friday morning, we’ve got a clean 5ft swell from the WNW, with a period of 10 seconds and a light cross-offshore breeze from the NNW. The combined energy is moderate, around 403, and with the wind being light and clean, the surf should be proper fun. The tide might be a factor, but the conditions are there for a good session. The swell direction is a bit off the optimum, but with that clean wind, it’s a solid pick. Be aware, crowds are a possibility here.
After that, it drops right off again. Saturday and Sunday are tiny, with nothing to get excited about. The whole following week, from the 24th to the 29th, looks pretty average. The wind is mostly onshore or cross-onshore, the swell is small, and the conditions are just poor. There’s a bit of a bump on the 30th of August, with a 5ft swell from the WNW, but the wind is onshore and the whole thing looks marginal at best.
Now, looking further out, things get interesting again, but it’s a long way off. On the 1st of September, we’ve got a big swell coming in – 8ft from the W, with a period of 10 seconds. The combined energy is massive, over 1400, but the wind is howling from the SSW at 31 mph, so it’s going to be a complete mess. Not one for the paddle.
The real standout, if you can wait, is the 2nd of September. Wednesday morning and afternoon both have a solid 7ft to 8ft groundswell from the W, with a period of 11 seconds. The wind is a clean cross-offshore from the NNW, and the combined energy is over 1000, so there’s plenty of power. This is expert territory at that size, especially with a period that long, which can make the waves a bit straight at the beach. But at St Tugen, with that wind and swell, it’s going to be a proper session. The only catch is that it’s a long way out, so keep an eye on the charts.
