The Lowdown
Alright, Rusty here again, switching to the old-school numbers.
The first week and a half out at Surfside Jetty is a real bummer. The water is sitting at a very unusual 75°, which is much warmer than normal for this time of year. From the start, right through to the 5th of September, we’re looking at small, weak swell with poor conditions. The combined energy is weak, mostly in the 200s (232), and the winds are onshore or cross-onshore, churning things up. It’s a real struggle for any kind of decent wave. The swell is tiny, around 2 ft to 3 ft, and the period is all over the place, but it doesn’t matter much when the wind is ruining it.
Now, the real story starts on Sunday the 6th of September. The finder shows a proper pulse of energy. We’re looking at a solid 8 ft swell from the south, with a long 15-second period. The combined energy absolutely jumps to 3440 – that’s strong, serious groundswell energy. The best part? The wind goes glassy in the morning, with a light breeze switching to a clean offshore from the northeast in the afternoon. This is the standout window. This is big, powerful stuff. At 8 ft, it’s not for the faint-hearted – this is expert territory. The long period means it’ll have plenty of punch and shape, but at a beach break, it might be a bit straight. For the experienced crew, this is the day to be in the water.
Monday the 7th still holds size, around 8 ft to 10 ft, but the wind gets messy, turning cross-offshore then cross-shore and choppy. The energy is still huge (2384, 2660), but the quality drops. Still a solid day for the brave, but Sunday is the pick.
After that pulse, the swell drops fast. From Tuesday the 8th onward, we’re back to small, weak conditions. The swell drops to 6 ft or less, the period shortens, and the winds go back to the onshore and cross-onshore garbage. The combined energy plummets back into the low hundreds (573, 230). It’s a frustrating return to flatness for the rest of the outlook.
Rusty.
