The Lowdown
Alright, I’m Rusty, and this is what we’ve got for Southerndown over the next 16 days. Honestly, it’s a rough stretch. The whole period is a tough slog, with wind and swell out of sync almost every day. There are no real standouts here, and the first decent-looking surf doesn’t show up until the end of the second week.
The water temperature is sitting at 67°F – that’s 6°F warmer than normal for this time of year, which is very unusual. You’ll be surfing in a wetsuit, but it won’t be as cold as usual.
The week starts with tiny, weak swell and bad wind. Sunday afternoon (6th September) has a 2ft WSW swell, but cross-on 20 km/h winds from the SSE ruin it, and the combined energy is a measly 32. Monday (7th) sees a jump in energy – 633 in the morning with a 4ft WSW swell and a 14-second period, which is a nice long groundswell, but it’s cross-shore and messy with a cross-chop. The afternoon gets worse: 5ft W swell, strong 25 km/h cross-on wind, and 1296 energy – but it’s choppy and unsurfable.
Tuesday through to Saturday (8th–12th) is a write-off. Swell sticks around 3ft to 5ft, but the wind is either cross-on or onshore, fresh to strong, and the water is lumpy. A few spots hit moderate energy (like 393 on Tuesday afternoon), but the quality is just poor.
Sunday morning (13th) is a glimpse of hope: glassy conditions with a 2ft WSW swell and light SE winds at 5 km/h. That’s the only clean window in the whole first week, but the swell is tiny (energy 51) and it’s inconsistent. Afternoon goes back to light cross-on and small ripples.
The next week drags on with similar problems. Monday (14th) and Tuesday (15th) are all cross-onshore chop. Wednesday morning (16th) finally brings a bigger swell – 7ft from the WSW with an 8-second period, cross-offshore NW wind at 15 km/h, and 615 energy. That’s the best looking wave of the whole forecast, but it’s a 7ft wave – that’s only for experienced surfers, and the short period (8 seconds) means it’ll be a bit weaker and more broken up. Thursday (17th) has a 5ft WSW swell with onshore wind, making it unappealing. Friday (18th) morning shows a 7ft WSW swell with light cross-on wind and 444 energy, but it’s still marginal.
Saturday (19th) onward fades fast: 4ft dropping to 1ft by Monday (21st), with energy dropping from 127 down to just 24. The wind stays cross-on or onshore, so it’s flat and ugly.
If you’re a beginner, the only safe-sized day is the glassy Sunday morning (13th) with 2ft, but it’s inconsistent. For experts, Wednesday morning (16th) with the 7ft WSW swell is the only real shot, but the wind is a bit cross-offshore, not perfect. For the rest, the combination of poor winds and messy swell makes this more of a kite-surfing setup than a paddle session.

Further information to help with frequently asked questions about our surf forecast for Southerndown may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
