The Lowdown

Alright, surfers, Rusty here. Let’s take a look at what’s brewing.

We’ve got a solid run of south-west swell coming in. The first few days are looking prime, with a mix of longer period groundswell and glassy conditions. The water temp is sitting at 77°F, which is a touch warmer than normal for this time of year, so you’ll be comfortable.

The standout session is shaping up to be Thursday, July 30th, at Black Rocks Jetty. The morning kicks off with a clean 5ft swell from the SSW at a long 13 seconds, and it’s dead glassy with a slight WNW breeze. The combined energy is pumping at 1019 (moderate). By the afternoon, the swell pushes up to 6ft with a 16-second period, and the energy jumps to 1373 (strong). It’s still glassy, but with a few rain showers. This is proper reef-break territory, so it’s for experienced surfers only.

Friday, July 31st, holds up well. The morning has a clean 6ft SSW swell (16s) with a light cross-off N breeze, keeping the surface tidy. The energy is still strong at 1305. The afternoon sees a similar 6ft swell (15s), with a light ENE cross-off breeze. This is a very solid day.

Saturday, August 1st, is another cracker. The morning is glassy with a 6ft SSW swell (15s) and the combined energy reading a strong 1447. The afternoon goes dead calm, with a 6ft SSW swell (14s) and 0 wind. You’ll be sharing the line-up with occasional crowds, but it’s a reef, so expect a few locals.

Sunday, August 2nd, the morning is still glassy and clean with a 4ft SSW swell (15s). The energy is at 1062 (moderate), but the afternoon gets a little messy with a cross-on breeze, so the morning is the call.

We then see a drop in size through the middle of the week, with smaller swells and some onshore winds. The surf will be smaller and more marginal, but there are still some glassy windows.

The action picks up again for the second week. Monday, August 10th, looks like a standout for the more experienced crew. The morning has a 6ft SW swell (15s) with glassy conditions, and the combined energy is a massive 1750 (very strong!). The afternoon is similar at 6ft SSW (15s) with a 1649 energy reading and light offshore wind. This is big, powerful, and only for experts.

Tuesday, August 11th, still has some punch with a 6ft SSW swell (15s) and glassy conditions in the morning. Energy is 1145 (strong). The afternoon turns onshore, so get it early.

The final week sees a mix of smaller swell and some interesting longer-period pulses. The Wednesday, August 12th afternoon offers a 6ft SSE swell but with a very short period of 7 seconds, so it’ll be a bit weak and messy. The Saturday, August 8th afternoon and Sunday, August 9th morning are worth a mention, with clean, glassy conditions and building 4ft to 4ft SW groundswell.

Overall, the first four days are your best bet. The 10th and 11th are the big ones for the experienced crew, but keep an eye on the forecast as it gets closer.

Rusty.
