The Lowdown
Right then, let's have a look at what's on the cards for Broadhaven South. It's going to be a bit of a mixed bag, and honestly, you're going to have to be patient. The 16-day window kicks off with a long, flat spell, so don't bother rushing down there for the first week or so. The first real chance of a wave doesn't show up until Sunday the 13th.
Alright, so Sunday the 13th of September. This is your standout window, no question. We've got a nice little pulse of WSW groundswell rolling in, with a clean 5ft on the push in the morning. The period is a decent 10 seconds, so there's some proper energy in the water (moderate wave energy around 415). The wind is going to be a light W breeze, which is cross-offshore, meaning it'll be groomed and clean. This is your best shot for a session – it's got quality written all over it. The swell direction is bang on from the SW, which is exactly what this sheltered spot wants. It's intermediate territory, but just be aware it's an inconsistent wave, so you'll be waiting for the sets. And being an inconsistent spot, when it does come together like this, it's worth the wait. The water temp is sitting about average for the time of year.
After that Sunday high, the week gets pretty ordinary. Monday the 14th sees the swell dropping and the wind turning onshore and cross-shore, making a mess of things. Tuesday the 15th has a clean morning with offshore wind, but the swell is weak and the period is short, just 5ft at 8 seconds. It's surfable, but it's not going to blow your hair back. The combined energy is a moderate 229. Wednesday the 16th is much the same story – a few small, clean waves in the morning, but nothing to write home about.
Then it gets really quiet. From the 18th of September right through to the 27th, it's a desert. The swell drops to knee-high at best, the energy is weak (under 100), and the wind flips around. We get a weird glassy day on the 23rd with a tiny 0.3ft, 17-second groundswell, but that's barely a ripple. For the last week of the window, you're looking at tiny surf and onshore winds. There's absolutely nothing to recommend.
So, to sum it up: your one and only play is Sunday morning, the 13th of September at Broadhaven South. Get it while it's clean and has a bit of power, because after that, the taps are turned off for a long while.
