Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here with a look at what Black Rocks Jetty has coming our way.

We’ve got a pretty wild ride ahead over the next couple of weeks, with some proper solid swell mixed in with a few windows of absolute perfection. The water temp is sitting at a comfortable 77°F, which is about average for this time of year.

The first proper call is Saturday afternoon, 4 July. It’s not going to be anything special – a 5ft SSW swell with a 13-second period, but the wind is blowing from the SW onshore straight into the spot. The combined energy is moderate (803) but the conditions are marginal, so this one’s really just a warm-up.

Sunday morning, 5 July, sees the swell dip a little to 4ft from the SW, but the period jumps to a long 16 seconds. That's a proper groundswell, and on a reef setup like Black Rocks it should wrap in nicely. The wind is cross-onshore though, so expect some bump on the surface. The energy is ramping up though (1488). By Sunday afternoon the swell gets a boost to 7ft from the SW (15 sec period) and energy is pumping (2030), but the wind is up to 15 km/h from the SSW and cross-on, making it choppy. A tough one to read.

Monday 6 and Tuesday 7 July are messy. Monday has solid 7ft swell but strong 25 km/h cross-onshore winds – downright poor. Tuesday is the big one: a 10ft southerly swell with a 12-second period, and the combined energy is massive at 4965! That’s strong, powerful stuff. But it's blowing 25 km/h cross-shore and the conditions are only marginal. This kind of size is for experienced surfers only.

Now, here’s where we get excited. Wednesday, 8 July, is a beauty. The morning has a 6ft southerly swell with an 11-second period, but the wind is NNE at 5 km/h and glassy. That’s clean. The afternoon gets even better with 7ft from the SSE, zero wind, and glassy conditions. Energy is solid (1333) and the surf report says it’s excellent for experienced surfers. This is a standout.

Thursday 9 July starts glassy again with a 3ft southerly, but it fades quickly in the afternoon.

Friday 10 through Saturday 11 July is our next true highlight. Friday morning has a small 2ft SW groundswell with a 15-second period and glassy conditions – ideal for a clean, longboard session. The energy is moderate (391). Friday afternoon is glassy again with 4ft from the SW, 14-second period, and a calm ocean. By Saturday 11 July, we’re in business: 5ft and 6ft SW swells, both with a 14-second period, glassy wind from the NW and N, energy building from 1009 to 1340. The surf report says excellent for experienced surfers. This stretch from Friday 10 July afternoon through Saturday 11 July is the best on offer.

After that, things get a bit lumpy. Sunday 12 July brings light rain and a 8ft SW swell with a 15-second period, but cross-onshore wind makes it marginal. The energy is high (2732) but the quality is lacking.

The middle of the following week, from 13 to 16 July, is mostly small and messy with cross-shore winds, though Wednesday 15 July morning and Thursday 16 July afternoon offer a brief glassy window on tiny waves.

Then, from Friday 17 July morning through Saturday 18 July afternoon, we get another run of very good conditions. Swells are 4ft to 4ft from the SSW, period is a solid 13-15 seconds, and the wind is calm or glassy. Energy is moderate (down from 959 to 377). Clean, easy-going waves for a fun session.

We finish up the outlook on Sunday 19 July with small, fading 3ft SSW swells and light cross-shore winds – not much to write home about.

Final call: The standout sessions are Wednesday 8 July, and the real gem is Friday 10 July afternoon right through Saturday 11 July. Get in the water.

Rusty.
