The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough run for Southerndown. The whole 16-day window is practically a write-off for decent surf. We’re looking at a long stretch of tiny, wind-affected swell, so you’ll be waiting a while for anything rideable.
The water temp is sitting at 69°, which is a massive 8° warmer than usual for this time of year – that’s very unusual, and honestly, if you’re getting in, you won’t need a thick suit.
The first week is a real struggle. Saturday the 1st kicks off with a tiny 2 ft west swell and a cross-onshore breeze, making it choppy and messy. The combined wave energy is weak at just 22. The next few days are similar with tiny 1.0 ft to 2 ft swells from the WSW. The best wind you’ll see in this period is on Sunday afternoon the 2nd, when it goes glassy, but the swell is still only 1.0 ft with a weak 8-second period – you’ll be bobbing around more than surfing. The combined energy is a paltry 13. On Wednesday the 5th, the swell bumps up to 4 ft from the WSW, but the period is a short 6 seconds, making it weak and bumpy, especially with a 16 mph cross-on wind. The energy hits 100, but the quality is poor. Thursday the 6th sees a similar 4 ft west swell, but a 19 mph cross-on wind makes it lumpy.
Friday the 7th through to the end of the first week and into the second is a washout. Swell sizes drop back to 0.3 ft to 1.0 ft, with periods all over the place. The wind might be light on Monday the 10th morning, but with a 0.3 ft, 7-second swell, there’s nothing to ride.
The second week is no better. From the 11th through to the 16th, we’re stuck with tiny 0.3 ft to 2 ft swells, mostly from the WSW, with cross-on winds from the west. The combined energy barely cracks 50 on the 13th, but it’s all for nothing with the poor conditions. The 14th brings some rain and a 28 mph cross-on wind, just to make it thoroughly unpleasant. By the 16th, it’s a 0.7 ft WSW swell with a gentle cross-on breeze – still not worth paddling out for.
Honestly, for this stretch, the setup looks more interesting for a kite session than for paddle surfing, if you’ve got the gear and the wind.
Rusty.
