Righto, let’s have a look at what’s on the cards for the next couple of weeks.

We’ve got a solid run of surf coming up, but it’s a bit of a mixed bag with conditions. The first standout is Black Rocks Jetty with a very strong SW groundswell arriving Sunday morning, July 12th. We’re talking 8ft of swell from the SW, with a period of 15 seconds – that’s proper long-period groundswell, full of energy (combined energy of 2699). The wind is light from the SW, but it’s onshore, so it’s a bit of a battle. The morning is a little marginal, but the afternoon glass off is where it’s at. The afternoon sees the wind go glassy, with 8ft of SW swell, 14-second period, and the water temp is a warm 76°F, which is about normal for this time of year. That Sunday afternoon session is going to be clean and powerful for the experienced crew.

Monday morning, July 13th, is a bit cross-on with a southerly breeze, but the swell is still a solid 7ft from the SSW. The real gem is Monday afternoon: glassy conditions with 7ft of SSW swell and 14-second period. That’s a dream window for the advanced surfer. Tuesday, July 14th, keeps the glass running with a morning glass-off and 6ft of SSW swell, and the afternoon turns offshore with a NE breeze, 5ft of swell, and clean conditions. That’s a cracking run.

The swell drops off through the middle of the week, with 4ft on Wednesday morning, July 15th, and offshore winds, then Thursday, July 16th, we’re down to 2ft – small but glassy. That’s more of a longboard or funboard session.

Now, we’ve got a real wildcard on the horizon. For the week starting July 20th, things get a bit messy. Monday, July 20th, is a write-off – strong cross-onshore winds and 8ft of swell, but it’s lumpy and poor. But hold onto your board – Tuesday morning, July 21st, is the absolute standout of the whole outlook. 10ft of S swell, 13-second period, with a light cross-offshore ESE breeze. The combined energy is a massive 4510 – that’s serious power. This is a big, clean, groundswell for experts only. The reef at Black Rocks Jetty will handle this size well, but it’s not for the faint-hearted. That’s the best on offer, no question.

The swell then backs off, but we get another clean, glassy window on Wednesday morning, July 22nd, with 4ft of S swell. Then, heading into the last weekend of the month, we have a classic SSW groundswell building again. Sunday morning, July 26th, is glassy with 7ft of SSW swell, 15-second period – another excellent session for the experienced crew. Monday, July 27th, keeps the size at 7ft from the SW, but the wind is cross-on, so it’s a bit more of a handful.

Overall, there’s plenty of action, but the absolute best windows are the glassy afternoon sessions on Sunday, July 12th, and Monday, July 13th, and the big, clean, powerful morning on Tuesday, July 21st. That Tuesday is the one to circle on the calendar.

Rusty.
