The Lowdown
Alright folks, Rusty here. Let’s look at the next couple weeks at Black Rocks Jetty. There’s a proper window of pumping swell coming, then it fades out to a long quiet spell before another pulse shows up far out.
The week kicks off with some nice, clean groundswell. Tuesday the 25th morning has a 6 ft SSW swell with a 13-second period, light west wind making it glassy. It’s got solid energy (1007) and the wave comment is excellent for experienced surfers. By the afternoon, still glassy at 5 ft, but the energy drops a notch (797).
Wednesday the 26th keeps the good times rolling—morning is 5 ft from the SW, glassy, with 12 seconds on the clock. The combined energy is back up (949). The afternoon sees a shift: smaller at 3 ft but the period jumps to a very long 18 seconds from the SSW. That’s proper groundswell energy (1144), and with a clean cross-off breeze, it’ll be lined up and offering some real quality for the experienced crew on this reef setup.
Then Thursday the 27th morning is the standout of the entire outlook. Big 10 ft SSW swell, a 17-second period giving it plenty of punch, and glassy conditions. The combined energy is massive (4932). This is a serious, powerful, clean swell—perfect for advanced surfers. It’s big, so leave the foam boards at home. The afternoon stays big at 10 ft, but the south wind gets cross-on, making it rougher and less inviting.
Friday the 28th the swell holds at 12 ft, but those southeasterly winds are cranking at 12 to 16 mph, cross-shore, creating a messy cross-chop. The energy is huge (7091) but the quality is gone; this setup looks more interesting for kite surfing than paddle surfing.
Saturday the 29th is redemption day. The swell is still a solid 12 ft from the SSW, period 15 seconds, but the wind drops to glassy in the morning. The energy is still very strong (4716), and the wave comment is excellent for experienced surfers. That Saturday morning session will be a true highlight, with big, clean lines. The afternoon drops a touch to 10 ft but stays glassy.
Sunday the 30th sees the swell easing to a still-chunky 7 ft, glassy morning, with energy at 1883. Good for the strong intermediates who want a taste of the bigger stuff.
After that, the wheels fall off. Monday the 31st drops to 4 ft, then it’s a slow bleed through the first week of September. From Tuesday 1st September onward, swell sizes fall under 3 ft, with combined energy dropping below 200, and the wave comments range from “ordinary” to “poor.” There’s a long gap of quiet surf from about Tuesday 1st September out to Saturday 5th September.
Saturday the 5th of September afternoon brings a tiny pulse back: 3 ft from the SW but with a long 16-second period, giving a touch of energy (377) and glassy conditions. Sunday the 6th of September morning builds a little more to 4 ft, glassy, 14-second period, energy at 672, and the wave comment is “very good.” A promising but distant flicker after a long dry spell. Monday the 7th gets messy with rain and onshore winds, and Tuesday the 8th looks marginal with cross-shore breeze.
The absolute best on offer is Thursday 27th August morning: 10 ft SSW, 17-second period, glassy, and massive energy (4932). That’s the one to circle. The runner-up is Saturday 29th August morning: still big at 12 ft with glassy wind, for the brave ones.
For the first break mentioned, Black Rocks Jetty, the water temperature is around average for this time of year—nothing unusual there.
Rusty.
