The Lowdown
Alright folks, let's have a look at what's on offer down at Southerndown over this forecast period.
Honestly, looking ahead, it’s a pretty grim run for the next couple of weeks. There’s nothing here that gets me excited at all. I’ve scoured the numbers and we’re staring down the barrel of a long, flat period with poor surf conditions pretty much all the way through.
The first real chance of a wave, if you can even call it that, doesn’t show up until Saturday the 25th of July in the afternoon, and even then it’s a messy situation. We see a weak 3 ft swell from the West with a short, gutless period of 4 seconds, and the combined energy is only 32 – that’s weak stuff. The problem is the wind is a fresh 19 mph cross-onshore, making for lumpy, blown-out conditions. It’s not worth paddling out for.
We get a slight bump on Sunday the 26th of July. The swell lifts to 4 ft from the West, with a slightly better 7-second period. The combined energy hits 120 (moderate), so there's a bit more push. But again, the wind is a moderate cross-shore breeze, creating a cross-chop. It’s going to be a messy, bumpy ride, and the quality just isn’t there. This is the best of a bad bunch, but I wouldn't call it a standout.
After that, we drop right back into tiny, weak swells and onshore winds for days and days. There’s a stretch from the 28th of July right through to the end of the forecast on the 7th of August where we see the swell height barely tickle 1 ft, the energy levels are in the single or low double digits, and the wind is mostly cross-onshore or simply not cooperating. There are a few brief moments of glassy conditions, like on the morning of the 28th and the 5th of August, but with swell heights of 1 ft and no energy, you’ll be sitting on a flat sea. A couple of sessions on the 3rd of August show a clean, light offshore wind, but again, with only 1 ft of swell, it’s a non-event.
So the honest truth is: leave the boards at home. The entire 16-day window is a write-off for surf at Southerndown. The forecast suggests a long, flat spell, and sometimes that’s just the way it goes around here. Maybe the forecasts will change, but right now, there’s nothing to paddle for.
