The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of surf on the way at Black Rocks Jetty, but you’ll need to be patient for the real gems.

The week kicks off with a bit of a slow start. Thursday the 16th has some small 2ft to 2ft SSW swell, but the wind is a cross-off, so it’s not really doing the spot any favours. Friday the 17th is similar, with a bump in size to 4ft but onshore winds, so it’s pretty messy. Saturday the 18th is more of the same—small, cross-on, not worth getting excited about.

Then we hit our first real standout. Sunday morning the 19th is a beauty. The swell drops back to 3ft, but it’s a clean, glassy 16-second SW groundswell. The combined energy is moderate (481), but with the wind dead calm and glassy conditions, this will be a fun, clean session on the reef. That’s the one to aim for early in the week.

Monday the 20th sees a big jump in size. The morning is 6ft SW at 14 seconds, glassy, and the combined energy has surged to 1271 (strong). This is excellent surf, but at 6ft, it’s edging into the territory for experienced surfers only. The afternoon is even bigger at 7ft and glassy again. The crowd factor here is “sometimes,” so you might get some company, but it’s worth it.

Tuesday the 21st and Wednesday the 22nd keep the quality high. Tuesday morning has 5ft SW at 12 seconds, glassy, with moderate energy. Wednesday is the pick of the mid-week with a 6ft morning and a 7ft afternoon, both glassy, both with strong energy (over 4300). The wind is offshore, so expect clean, lined-up waves. These are for experts only.

Thursday the 23rd is a bit of a mixed bag—morning glassy with 4ft SW, but the afternoon goes onshore and the quality drops. Friday the 24th has a very long-period 16-second SW groundswell at 5ft in the morning, glassy, with strong energy (1389). That long period will make the reef (Black Rocks Jetty) work beautifully, but it might be a bit straight for a beach break. The afternoon is a touch bigger at 5ft but with a cross-on wind, so it’s a bit less clean.

Now for the second week. Saturday the 25th and Sunday the 26th are absolute standouts. Saturday has 4ft to 5ft SW, glassy, with strong energy. Sunday the 26th is the big one: a 8ft SSW swell at 15 seconds, glassy, with very strong energy (3050). This is a serious, expert-level swell. The wave state is excellent, and the wind is offshore. This is a true standout for the whole period.

Monday the 27th has a 7ft morning, glassy, and strong energy, but the afternoon gets a cross-on wind. Tuesday the 28th is a bit wild: 6ft SW but with a very long period of 18 to 20 seconds from a cross-shore wind. The energy is extremely high (4290), but the wind is across, so it’s a “marginal” call. That’s a lot of power for a reef with a cross-shore wind.

Wednesday the 29th and Thursday the 30th are the final real gems. Wednesday has 6ft to 7ft SSW, glassy, with strong energy. Thursday the 30th is a monster: 8ft SSW at 17 seconds, glassy, with very strong energy (3353). That’s an expert-level, big-wave day. The afternoon is also glassy at 8ft. Friday the 31st winds down with a 7ft morning but a cross-on wind, so the quality fades.

The water temperature is about average for this time of year, so no surprises there.

Overall, the standouts are Sunday the 19th for a clean, fun session, and then the big, glassy days from Sunday the 26th through Thursday the 30th for the experienced crew. The swell direction is mostly SSW to SW, which matches the optimum direction for Black Rocks Jetty, so the reef will be firing.

Stay safe, and I’ll see you out there.
