The Lowdown
Hey there, Rusty here. Gotta be straight with you – it’s looking pretty grim on the surf front for a good long while. We’re staring down a big stretch of flat or just plain messy conditions before anything halfway decent shows up.
We’ve got a nasty gap of poor to no surf starting now and running all the way to Friday the 29th of August. That’s over a week of little to no hope. That little spike of swell on the 28th looks massive on paper – a 13ft swell from the WSW – but the combined energy is off the charts (2808) and the wind is howling onshore. That mess is for the kite crew, not us.
The one true standout comes on Saturday, the 29th of August. Broadhaven South finally offers something. Early doors we’ve got an 8ft groundswell from the WSW with glassy, clean conditions. That’s a proper swell, with a combined energy of 1020. This is not a learner’s wave; anything over 8ft is expert territory here. The water’s sitting at 64°, which feels a touch warmer than average, so that’s something.
The good conditions hold into Saturday afternoon with a cleaner 6ft and offshore wind. A solid session if you’re game. After that, it’s back to tiny, weak dribble for the rest of the outlook. Mark your calendar for Saturday the 29th.
