The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you… this next fortnight at Southerndown is a write-off. There’s not a single surfable moment in the whole 16-day window, from the 2nd of September right through to the 17th. Every session is rated as poor surf conditions, and honestly, it’s a brutal run.
Right from the get-go, Wednesday the 2nd kicks off with rain showers and a howling onshore wind gusting 22 mph out of the WSW. Swell’s a messy 5 ft with a short, weak 7-second period – the combined energy is only 216, so it’s weak and wonky. Water temp is 68°, which is a wild 7° warmer than normal for this time of year – a freakish warm spell that doesn’t help the slop.
That same pattern sticks around for days. Thursday the 3rd, Friday the 4th, and into the weekend – swell wobbles between 2 ft and 6 ft, but the wind is always cross-onshore or onshore, mostly fresh breeze to strong breeze. Saturday the 5th and Sunday the 6th are tiny and choppy, with energy dropping as low as 30. Not worth a paddle.
Monday the 7th sees a spike to 6 ft from the WSW and a 9-second period, energy jumps to 667 (moderate), but the wind is still cross-onshore at 22 mph, killing any chance of a clean face. Tuesday the 8th through Friday the 11th is more of the same – cross-onshore winds and lumpy conditions. The best you get is a brief cross-off on Sunday morning the 6th, but that’s on a measly 1 ft wave. Forget it.
From the 12th of September onward, it gets even smaller – 2 ft down to 0.7 ft, with periods all over the place. A 10-second period appears on Sunday the 13th, but the swell is barely a ripple (energy 77) and the wind is fresh and lumpy. The final few days, the 16th and 17th, are just pathetic – 1.0 ft and 0.7 ft, with a howling near gale on the 16th afternoon. Clean but tiny.
There’s no standout, no hidden gem, no consolation prize. Southerndown is a beginner-friendly, fairly consistent break that’s fairly exposed to the SW, but not even that helps here. With the consistent cross-onshore wind and mostly weak energy, it looks more like a kiteboarder’s day than a surfer’s. The blank run is long but for this spot, when the wind and swell line up wrong, it can go quiet for stretches. Don’t hold your breath.
Rusty.
