Black Rocks Jetty Surf Forecast and Surf Report

Righto, Rusty here. Let’s have a look at what’s on the cards for Black Rocks Jetty over the next couple of weeks.

First up, it’s not looking pretty for Monday the 6th and Tuesday the 7th of July, with messy, cross-onshore winds and some pretty raw conditions. There’s a solid 7 to 10ft south-west and south swell running, but the wind has it chopped up bad, so I’d give those days a miss unless you’re keen on a wrestle. The combined swell energy is moderate to strong (around 1462-4091), but it’s wasted.

Wednesday the 8th, though, that’s when things get interesting. The wind drops right off – glassy conditions in the morning – and we’ve got a clean 5ft south swell with a period of 10-11 seconds. The wave energy is moderate (around 609). This is a proper window for a session, especially if you’re looking for clean, lined-up waves. Not huge, but well-shaped and fun.

Thursday the 9th and Friday the 10th see the swell ease to under 3ft, with a long-period groundswell from the south-west on Friday (15 seconds), but the energy is on the lower side (246 to 461). Glassy mornings, good for a longboard or a cruise, but nothing to get too excited about.

Now, Saturday the 11th shapes up nicely with a 5ft south-west groundswell (15-second period) and a clean, cross-offshore wind in the morning. The energy picks up to moderate (959), and the waves should have some punch. The afternoon brings a bit of rain and a cross-shore breeze, so get in early.

The standout period, without a doubt, is Sunday the 12th and Monday the 13th of July. This is the one to circle on your calendar. We’ve got a solid 8ft to 8ft south-west swell on Sunday, with a long period of 14-15 seconds, and glassy conditions all day. The wave energy is strong (2307 on Sunday morning). This is serious groundswell – faster, more powerful waves, and with that direction hitting the jetty, it should be offering some proper, well-shaped right-handers. It’s in the “excellent for experienced surfers” range, and that’s exactly what it looks like. Monday the 13th holds onto a glassy 6ft of south-west swell in the morning too, with a similar energy level (1438). If you can handle the size and the crowd (it’s listed as “sometimes” busy), this is the absolute best of the whole run. Because the swell is over 5ft, it’s not one for beginners – you’ll want to be comfortable in solid waves.

The week following that keeps the consistent south and south-west swell rolling, with clean, glassy mornings from Tuesday the 14th right through to Wednesday the 15th and Thursday the 16th. Swell heights sit between 4ft and 5ft, with periods that go long again – 17 seconds on the 14th afternoon is a very long period groundswell. Energy stays moderate to moderate-strong (645 to 1425). This is consistent, clean, and perfect for anyone who missed the big Sunday session. It’s all reef-break territory, so those long-period swells will stand up nicely on the jetty structure.

Friday the 17th and Saturday the 18th see the swell drop away fast. Friday morning has a small 3ft clean wave, but by Saturday it’s down to 2ft, with a bit of cross-onshore wind and rain. The energy falls to around 123-250, so it’s a flat end to the week.

But then, looking at Sunday the 19th and Monday the 20th of July, we get another pulse of solid swell. Sunday morning kicks off with 5ft from the south-west (16-second period), building to 7ft in the afternoon. Monday the 20th holds a clean 7ft south-south-west swell with 14-second period. Both days show glassy winds and excellent conditions for experienced surfers, with strong wave energy (1196 to 2002). That Sunday/Monday run at the end sounds very promising, but it’s over a week away, so treat it as a hopeful forecast rather than a sure thing.

Overall, there’s good surf here. The absolute pick is Sunday the 12th, closely followed by the Monday the 13th morning for that big, glassy south-west groundswell.

Rusty.
