The Lowdown
G’day, Rusty here. Well, to be straight up with ya, it’s a pretty bleak run ahead at Middles/Generals. This stretch is exposed to the swell, and the optimum direction is ESE, but what we’ve got on the cards just isn’t lining up. The whole 16-day window is a struggle, and you’re gonna have to sit this one out unless you’re desperate for a paddle.
Let’s start with Wednesday the 9th. Wednesday morning has a small 3 ft swell from the SSW with a 14-second period, and the energy is moderate at 631. The water temp’s sitting average for this time of year. There’s a light NE breeze at 6 mph making it cross-shore, so there’s a bit of ripple on it. It’s marginal, and honestly, not worth rushing for. Wednesday afternoon drops off even more with the same size but shorter period and a gentle breeze—still just a marginal, lacklustre vibe.
From Thursday the 10th right through to Tuesday the 24th, it’s a long, grim stretch. Nearly every session is marked as poor surf conditions. The wind is a constant problem—ENE blowing anywhere from 12 mph to 25 mph, mostly cross or cross-onshore, creating chop and lumpy conditions. The swell bounces around between 1 ft and 7 ft, but with short periods mostly under 10 seconds, it’s weak and messy. Even when the energy kicks up—like Wednesday the 18th with a 3 ft SSW swell and a long 17-second period giving strong energy (1199)—the wind is still a strong 25 mph cross-shore, trashing any chance of clean waves.
There is one stand-out moment if you’re looking hard: Wednesday the 16th afternoon. We get a 3 ft SSW swell with a very long 18-second period, and the energy is strong at 731. But the wind is a fresh 22 mph cross-shore, so it’ll be lumpy. If you absolutely have to get wet, that’s the closest thing to a pulse, but don’t get your hopes up. For experienced surfers only, and even then it’s a gamble.
Overall, the consistency is fair, but the quality just isn’t there. The constant cross-shore winds dominate, and the swell direction rarely matches the optimum. It’s a blank run, plain and simple. Might be worth waiting for a change in the forecast, because this stretch looks more interesting for kite-surfing than paddle-surfing with all that side wind.
Rusty.
