The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the coming days.
To be straight with you, the next week and a half is a bit of a write-off for decent surf. We’ve got a long gap with very little to recommend. The first real glimmer of hope doesn’t show up until Saturday the 15th of August, and it’s a blink-and-you’ll-miss-it window. The wave energy is moderate (578) through the morning, with a clean 5.9ft swell from the WNW and a 10-second period. The wind is gentle offshore from the north, so it’ll be clean. That’s the standout of the whole outlook, no question, and it’s the only time conditions really come together.
Before that, we’re looking at days of small, weak, or messy surf. The middle of the first week has some tiny waves, but nothing worth paddling out for. The water temp is about average for the time of year at Porsmilin, so no surprises there.
The real excitement, if you can call it that, lands on Monday the 17th of August. We’ve got a solid 6.6ft swell from the WNW ramping up overnight, with strong energy (833). The morning looks clean under light winds, but the period is short at 8 seconds, so it’ll be a bit crumbly on the sandbar. Still, it’s the biggest swell of the forecast. By the afternoon, the wind swings cross-shore and the energy drops a bit, so the morning is the pick.
After that, things get ugly. Tuesday the 18th sees a big 9.8ft swell from the WNW, but the wind is howling from the WSW at 22 mph, making it a lumpy, onshore mess. The energy is huge (3263), but that’s for the kite surfers, not paddle surfers. The afternoon cleans up a touch with a cross-offshore wind, but the size and power are still only for experts.
The final few days look poor with more onshore wind and choppy conditions. Nothing to get excited about.
