The Lowdown
Alright, this is Rusty. Let’s break down what’s on the table for Broadhaven South over the next couple weeks.
It’s a challenging stretch. The first week is mostly a no-go – small, choppy, or just awful conditions. The real big deal is that massive swell hitting around September 8th, but that one’s not for everyone. Early on, it’s dead quiet, with hardly a wave worth mentioning through the end of August. Things perk up a bit on Monday August 31st with a clean offshore wind and some building swell, but it’s still a mixed bag.
The absolute highlight is Tuesday September 8th. That morning and afternoon, a serious southwest groundswell slams in at 18ft to almost 20ft with a long 11-second period from the WSW. The combined swell energy is massive – through the roof at 6770 and 7905 – that’s a ton of power. Wind is a strong offshore from the WNW, making it clean. This is expert only territory – anything over 8ft is for experienced surfers only. With that long period and big size, it’s a heavy, powerful beast. Leave it to the guys who know what they’re doing.
Before that, the best bet for a decent wave is Monday August 31st afternoon. The swell is 6ft from the WSW with a moderate offshore wind from the WNW. It’s clean and rideable, with moderate wave energy (551). A solid option for intermediates who don’t want to wait for the monster on the 8th.
After the 8th, it drops off fast. Wednesday September 9th is smaller at 5ft, clean but nothing special. And then from the 10th, it gets messy again with onshore winds and poor conditions.
Water temp is a notable 65°F, which is about 4°F warmer than average for this time of year – pretty unusual, so you might get away with a thinner suit.
A quick note: for Thursday the 10th and Friday the 11th of September, the swell is still around 5ft but with strong onshore winds and lumpy conditions. That setup looks more interesting for kite surfing than paddle surfing.
So, the plan: wait for Monday August 31st afternoon for a clean, fun session, and if you’re an expert, circle Tuesday September 8th for a massive, powerful groundswell. Everything else is a grind.
Rusty.
