The Lowdown
Alright folks, Rusty here with a look at the upcoming swell window for Black Rocks Jetty. This is a proper reef set-up for advanced surfers only, and the next couple of weeks have a few windows of opportunity.
The standout session is hands down the morning of Wednesday, September 16th. We've got a solid 8ft SSW groundswell (very long 15-second period) rolling in, with glassy conditions and slight air. The combined energy is pumping at 3221 – that's strong to very strong energy. This is a proper, powerful reef swell. For the experienced crew, this is the pick of the fortnight. Just be aware, at this size it's expert territory only. The water temp is sitting at 75°F, which is about average for this time of year.
Sunday, September 13th morning is another good call. It's a touch smaller at 5ft from the SSW, but with a very long 17-second period and glassy conditions. The energy reading is 1820 – still strong. It’s a great way to kick things off, but remember the crowds can be an issue here sometimes.
Tuesday, September 15th afternoon also looks clean. A 6ft SSW swell with a 17-second period and glassy conditions (energy at 2011). That's another solid, clean session for the experienced surfer.
Thursday, September 17th afternoon sees the swell drop to 4ft from the S, but with calm, glassy conditions and moderate energy (556). It's a smaller, cleaner option for a quieter paddle.
After the 16th, the swell slowly fades through the rest of the week and into the second week. Monday, September 28th afternoon brings a bit of a pulse – a 3ft S swell with a 16-second period and clean, cross-off wind. The energy is moderate at 558, making it a decent option for a clean, smaller wave.
From around September 19th through to the 27th, most days are small and marginal, with only a few clean windows for a tiny wave. The 20th morning and 26th morning offer clean, small 3ft SW swells, but it's really just a cruiser board or longboard situation. The gap between the main action and these smaller pulses is noticeable.
Overall, the first week has the most punch. Lock in that Wednesday morning if you can handle the size and the reef.
Rusty.
