The Lowdown
Alright, this is Rusty checkin' in from Black Rocks Jetty. We've got a solid 16-day window ahead, but it kicks off with a bit of a rough patch before we hit some real gems.
The forecast starts this Friday the 28th of August, and honestly, it's a bit of a mess to begin with. We've got a big 13ft SSW groundswell rollin' in with a 16-second period, and the energy is massive at 7697. But the wind is a fresh 19 mph SSE breeze, cross-on, and it's just lumpy and poor. Not what you want to paddle into. The afternoon cleans up a little, but it's still a cross-shore chop. Not worth the fight.
You'll want to wait for Saturday the 29th of August. That's when the magic starts. The swell drops to a still-chunky 12ft from the SSW, period hangs at 15 seconds, and the wind swings to a light 3 mph Easterly, making it cross-offshore and clean. This is a standout window for experienced surfers. The energy is still strong at 4900, and the conditions are excellent. Saturday afternoon is just as good, with 10ft swell and clean conditions. That's the time to get wet.
Sunday the 30th of August morning is a treat. The swell eases to 8ft from the SSW, still a long 14-second period, but the wind goes glassy from the WSW at 3 mph. It's clean, glassy, and perfect for the advanced crew. The energy is still moderate at 2048.
The water temp is about average for this time of year, so no surprises there.
Then we have a bit of a lull from Monday the 31st of August through to Friday the 4th of September. The swell drops off, and while there are some clean, glassy moments, the wave heights are small (1ft to 5ft) and the energy is weak to light. Nothing to get excited about.
But hold onto your board, because Saturday the 5th of September is a beauty. The swell picks up to 5ft in the morning, then 7ft in the afternoon, both from the SW with a long 16-17 second period. The wind is glassy, the energy is strong (1389-2070), and the conditions are excellent. That's a standout for the forecast period.
The following week, from the 6th to the 12th of September, continues to deliver. We've got a run of clean, glassy mornings with solid SW groundswells, ranging from 4ft to 7ft, and periods from 13 to 17 seconds. The energy is moderate to strong. The morning of Monday the 7th of September is a standout, with 6ft SW swell, a 17-second period, and glassy conditions. The afternoons can get a bit tricky with some rain showers, but the mornings are pure gold.
The final Saturday the 12th of September has a 7ft S swell with a 15-second period, but a light cross-onshore breeze will put a bit of texture on it. Still surfable, but not as clean as the rest of the week.
So, the best of the best? Lock in for Saturday the 29th of August for the big, clean groundswell, and Saturday the 5th of September and Monday the 7th of September for the glassy, long-period perfection. Get out there and score.
