The Lowdown
Right, folks, Rusty here. Let's get into it.
Honestly, looking at the next 16 days for Alkantstrand, it's a real mixed bag. We’ve got a long wait for anything worth paddling out for, so be patient.
The water temp is sitting around 69.8°, which is pretty much what you’d expect for this time of year – nothing wild there.
The first proper chance doesn't come until Thursday the 17th of September, and even then it's a marginal call. We get a fresh offshore wind from the SSW, cleaning up a 5.2ft easterly swell. The combined energy is moderate (617), so there's some push, but it's a "marginal" call, so keep your expectations in check.
Friday the 18th looks promising on paper, but it’s for experts only. The swell jumps to 8.2ft from the SSW with an 11-second period, giving the water some serious energy (1773). The wind is light and offshore from the SSW, meaning it should be clean *and* big. This is a standout for the big wave crew, but if you're not experienced, give it a wide berth.
Saturday the 19th and the 20th both have offshore winds and solid swell, but again, the size is the story. Saturday has a 9.8ft S swell (1351 combined energy) with a light cross-offshore breeze, and Sunday the 20th morning offers a 6.2ft SSE swell with a moderate offshore breeze (582). That Sunday morning is probably the best bet for the average surfer – it's still solid but not terrifying, and it'll be clean.
After that, the window closes fast. Monday the 21st has a clean 5.9ft ESE swell in the morning (773), but by the afternoon it’s too big again at 7.2ft. Tuesday the 22nd is the same story: clean, big, and for experts only (7.5ft ESE, 1297 energy). After that, we slip back into a few days of poor, choppy conditions from Wednesday the 23rd through to the end of the month.
So, the only true standout here for the general surfer is Sunday the 20th of September – a clean, solid SSW swell with moderate offshore wind. For the big-wave chargers, Friday the 18th is the call. Don't expect much else.
