The Lowdown
Alright folks, Rusty here. Let’s have a look at what Porsmilin’s got cooking for us.
Right off the bat, the next few days are a write-off. We’re looking at a stretch of poor, messy conditions from Sunday the 30th right through the first week of August into September. The wind is a problem: strong onshore and cross-onshore, whipping up a chop. You’ll be fighting a fresh breeze and a lumpy ocean with combined swell energy sitting around 400 to 486 (moderate), but it’s just not worth it. The swell is there, but the quality is cooked.
We’ve got a dry spell until Friday the 4th of September. That’s a solid gap of almost a week with no real reason to paddle out. But hold onto your leash, because Friday morning is the standout. The water temperature is about average for this time of year, so no surprises there.
Friday the 4th of September morning is the one. We’ve got a solid 12ft swell rolling in from the WNW with a very long period of 14 seconds – that’s proper groundswell, lots of energy. The combined energy reading is a massive 4223, which is very strong. Now, the wind is a moderate cross-shore breeze, which will keep it clean. The catch? This is a sandbar break, and 12ft is not a beginner wave. It’s expert territory. That long period, 14-second swell can make a beach break like this wall up and close out, but on a good sandbar, it will be a sight to see. The wind and tide are favorable, but the sheer size makes it one for the experienced crew.
Saturday the 5th of September afternoon is your next best window. The swell drops to 5ft from the WNW with a 10-second period, and the wind goes light and cross-offshore from the NW. The combined energy is 539 (moderate), and the conditions are clean. It’s a much more manageable size, better for the intermediates. The crowd factor is “sometimes,” so you might have some company, but it’s a much friendlier paddle-out than the Friday morning beast.
The second week is a bit of a mixed bag. Sunday the 6th is a no-go with strong onshore winds. Monday the 7th is lumpy and cross-onshore. The standout in the second week is Sunday the 13th of September. The morning sees a 7ft swell from the W with a 12-second period, and a cross-offshore wind from the NW. The combined energy is 1538 (strong), and the conditions are clean. The afternoon is similar with a 6ft swell and a clean cross-offshore breeze. The numbers are decent, but it’s a long-range call, so keep an eye on it.
So, to sum it up: the first week is a bust. The absolute best on offer is the Friday the 4th of September morning for the big-wave specialists, and the Saturday the 5th of September afternoon for a cleaner, smaller session. The second week has a promising window on Sunday the 13th of September.
Stay safe out there.
Rusty.
