The Lowdown
Alright folks, Rusty here with a look at what Broadhaven South has in store for us over the next couple of weeks. Honestly, it's a bit of a mixed bag, but there are a few moments that’ll get the heart pumping.
The water is running pretty warm, about 65°F, which is a solid 4°F above what you'd expect for late August. That's a notable difference, so you can probably get away with a spring suit for a dawn patrol.
The first week is honestly a grind. There's a bit of swell around, but the wind just won't play ball. Saturday the 29th kicks off with a gusty 16 mph cross-on shore from the south, making a mess of the 5ft SW swell. By the afternoon, the wind swings west and cleans it up a little, giving us a cleaner 5ft SW swell, but the whole day is a write-off for quality sessions.
Sunday the 30th is a no-go with a fresh cross-shore breeze making for lumpy, choppy 7ft surf. Monday the 31st is the best of a bad bunch early on, with a strong 22 mph offshore from the northwest cleaning up a 8ft WSW swell. The energy is really starting to build, and it looks clean, but it’s still a bit full-on and the tide conditions might make it tricky. The trend continues through Tuesday, Wednesday, and Thursday with similar stories: consistent swell but the wind is just too strong, gusting 19-25 mph.
We finally get a reprieve on Monday, September 7th. The morning looks like the standout for days. The swell drops a little to 6ft from the west, but it's packing a long 11-second period, which means proper groundswell energy. The wind drops right off, barely a whisper from the north at 3 mph, creating clean, cross-off conditions. This is a true winner. This would be a much better fit for a point break or a reef than the beach, given that long period, but if she's holding, the shape will be quality.
We go through another quiet and generally poor spell with small, onshore surf before something catches my eye for Sunday, September 13th. That morning shows a 6ft west swell with a 7-second period, building to a 5ft swell in the afternoon with a very long 12-second period. The combined energy jumps right up as the day goes on. The wind is light and glassy from the west-southwest, giving us clean cross-off conditions. It's far out, so keep your fingers crossed, but this is another true standout. The long period again suggests a reef or point break will be your best bet for a proper wave. The afternoon session could be the pick of the trip.
So, if you can, sit out the windy days of this week and lock in Monday the 7th morning. For the patient ones, the long-range call for Sunday the 13th afternoon looks like it could be a beauty.
Rusty.
