The Lowdown
Alright, Rusty here again, but this time in feet and miles per hour. Let’s break down what Indian River (Southside) has in store.
The first week and a half is a write-off, plain and simple. From the 5th of September onwards, the swell is tiny, mostly under 3ft, with weak energy readings. The wind is a mess, often onshore or cross-onshore, leaving the surface choppy. We’re looking at a long stretch of poor surf conditions.
There’s a little moment of hope on Sunday the 13th, with a glassy morning and 0.8m (about 3ft) swell from the East. The wind is glassy, dead calm. The waves are surfable but very ordinary, just small and weak.
The only real highlight, the one you’ve been waiting for, is Thursday the 17th of September. The swell jumps to 2.2m (around 7ft) from the East with an 8-second period. The combined energy is strong, at 627. The wind is cross-off from the WSW at 15 km/h (9 mph), making for clean conditions. This is the best session of the whole outlook. At 7ft, it’s a powerful, heavy wave, strictly for the experienced surfers. The water is much warmer than normal, at 25° with a 3° anomaly. Thursday afternoon is similar, with 2.3m (8ft) swell and energy at 736, but with a light cross-onshore wind from the NE at 10 km/h (6 mph), so a few ripples will be on it.
Friday the 18th and the weekend after that drop back down to poor, onshore conditions.
So, there’s a big, empty gap for over a week until Thursday the 17th. That’s your day if you’re an advanced surfer looking for some clean, solid waves. For the rest, it’s a waiting game.
Rusty.
