Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at the next couple of weeks for Black Rocks Jetty.

The pattern shaping up is a slow start, but patience is going to pay off big time. The first few days are pretty average, but then we get a proper pulse of strong, consistent SW groundswell that will have this reef firing. The water is sitting at 76°F at the start, which is a touch warmer than usual for this time of year (anomaly of 2°F), so it’s a bit of a treat.

Saturday 18th July is a bit of a write-off. The morning has a 3ft S swell at 13 seconds, but it’s onshore, and the wave comment is marginal. The afternoon goes downhill with a cross-on shore breeze and poor conditions. Not worth paddling out for.

Sunday 19th July looks better in the morning. The swell drops a fraction to 3ft, but it’s a cleaner SW groundswell with a 16-second period and glassy conditions. The wave energy is moderate (452). It’s a small day, but it’ll be clean if you’re on a log.

Monday 20th July is where things start to get exciting. A solid 7ft SSW swell rolls in overnight with a 14-second period. The morning is glassy, and the combined energy jumps to a strong 1987. This is excellent for experienced surfers, but that 7ft is getting a bit big for beginners. The afternoon holds similar size at 8ft, still glassy. This is a standout window.

Tuesday 21st July keeps the quality high. You’ve got a 6ft SSW swell, 12-second period, and glassy offshore winds (N) in the morning, with strong energy (1016). The afternoon is clean too, with a WNW breeze. Excellent, clean surf.

Wednesday 22nd July gets a bit messier. The swell holds around 5-6ft, but the wind goes cross-onshore and cross-shore, putting some chop in the water. Still surfable, but not the cleanest.

Thursday 23rd July sees the swell easing to 5ft, with a glassy morning and a 12-second period. It’s a very good, clean option for the intermediate crew.

Friday 24th July looks like a sweet little day. A 4ft SW groundswell with a 15-second period, glassy in the morning. That long period will make it feel bigger and more powerful, but it’s a great size for most.

Saturday 25th July and Sunday 26th July are a bit of a mixed bag. Saturday sees small, weak swell (4ft, 652 energy) with cross-on wind. Sunday morning is tiny (2ft) but with a very long 20-second period and glassy conditions – it’ll be super clean but small. The afternoon gets a bump in size (5ft) but with rain showers and cross-on wind.

Monday 27th July is the absolute standout of the whole forecast. This is a serious swell. We’re looking at a 10ft SSW groundswell with a 17-second period, glassy in the morning. The combined wave energy is a massive 5905. This is exceptional, expert-level surf. It’s too big for anyone but the best. This is a huge, powerful groundswell that will be at its best on a reef like this.

Tuesday 28th July and Wednesday 29th July keep the size hefty at 10ft. Mornings are glassy, afternoons get a bit onshore. Still, for the experts, this is a solid run of big, clean waves.

Thursday 30th July sees the swell ease back to 5-6ft, with glassy conditions and a 14-second period. Excellent conditions for experienced surfers again.

Friday 31st July through to the start of August, the surf drops back to a more manageable 3-5ft, with clean conditions. A nice end to the run.

The standout sessions are the glassy mornings of Monday 20th July and Monday 27th July. The 20th is a great size for experienced surfers, and the 27th is a proper big-wave day for experts only. The jetty is a very consistent reef, so it’ll handle the swell well, but keep in mind that when the swell is that big and long-period, it can be a bit of a handful. Crowds are possible here from time to time, so get in early.

Rusty.
