The Lowdown
Alright, this is Rusty, and I’m looking at your local outlook for the next couple of weeks. We’ve only got one spot that’s really on the radar, and that’s Black Rocks Jetty (reef break). The water here is sitting at 77°, which is a couple of degrees warmer than what we’d usually expect for this time of year – that’s a pleasant surprise.
Right off the bat, we’ve got a standout. Saturday the 29th of August is looking absolutely killer. The morning is glassy, with a solid 12ft SSW groundswell rolling in with a 15-second period. The combined energy is massive at 4900 – that’s a lot of power. This is strictly for the experienced crew; it’s not a day for beginners. The afternoon stays glassy with 10ft SSW swell, still pumping. This is the best session of the whole run.
Sunday the 30th drops off a bit. The swell drops to 8ft, but the wind swings cross-on, so it’s not as clean. The energy is still decent at 2048, but it’s a step down. Monday is smaller again, around 4ft, and pretty average until the afternoon when the wind goes glassy – that’s a small window of clean, small waves.
Then we hit a flat spell. From Tuesday morning (September 1st) through to Friday morning (September 4th), it’s all under 3ft. The combined energy drops to triple digits, and the wave quality is ordinary. Basically, a few days of nothing much to write home about.
Things start to perk up from Friday afternoon (September 4th) with a clean 3ft SW swell and a slight cross-off breeze. Still small, but it’s a sign of life. Saturday the 5th is a bit bigger at 5ft, but the wind is messy again.
Now, here’s the next real highlight. Sunday the 6th of September morning is glassy with a 5ft SW groundswell, period of 16 seconds, and energy of 1267. That’s a clean, solid session for those who know what they’re doing. Monday the 7th gets bigger, with 8ft SSW swell in the morning and 12ft in the afternoon, but the wind is cross-on or cross-shore, so it’s not as perfect. That’s big, powerful stuff – definitely for experts only.
The following week continues to show promise. Tuesday the 8th has a 7ft SSW swell in the afternoon with a gentle offshore wind from the NNE – that’s clean and ripe for the taking. Wednesday the 9th is clean again with 4ft swells, and the pattern holds through to the weekend.
The real gem in the second week, though, is Saturday the 12th of September. Morning is glassy, 7ft S swell with a 19-second period – that’s a very long-period groundswell. The energy is huge at 4724. The afternoon is glassy again with an 8ft SSW swell. This is a full day of epic, clean, powerful surf. Just remember, a long-period swell like this will break a bit better at a reef break like Black Rocks Jetty, so that’s a bonus.
Sunday the 13th is still good, with 6ft and glassy conditions in the morning, but it’s a bit of a comedown from the day before.
So, to wrap it up: the absolute best two days are Saturday August 29th and Saturday September 12th. Both have clean, glassy conditions and solid, powerful swell. The first week has a big gap of flatness mid-week, but the second week is more consistent. Keep an eye on that long-range forecast for the 12th – it’s looking prime.
Rusty.
