The Lowdown
Alright folks, Rusty here. Let’s cut through the data and talk about what’s really happening.
Honestly, the next week and a half is a bit of a struggle for surf. We’ve got a long stretch of tiny, weak swell and onshore winds that just won’t give us a break. The combined wave energy sits at feeble numbers like 18 to 22 (weak energy) for most of that time, with waves rarely cracking 2 ft. It’s mostly cross-onshore breezes and choppy conditions, so don’t expect much – it’s poor surf, day after day. The water temperature is about average for this time of year, nothing unusual.
Now, the one glimmer of hope comes much later. On Tuesday morning, September 8th, we finally see some life. Agios Ioannis, a point break that’s exposed to the swell, will start to pick up some energy. The morning looks clean with glassy conditions – a light wind from the ENE, basically no breeze. The swell will be 5 ft from the ENE with a period of 7 seconds, and the combined energy hits 274 (moderate wave energy). That’s the best window we’ve got. It’s an intermediate-level spot, and it’s inconsistent, so don’t expect it to be pumping all day, but that Tuesday morning is your standout. The wind is perfect, the waves are a decent size, and the direction is right on the money for the optimum NE swell direction. It’s a solid pick for a session.
The rest of the forecast is a lot of waiting. You’ll see a few days with glassy moments but no real swell to push them, so don’t get your hopes up. That Tuesday morning is the one to circle.
Rusty.
