The Lowdown
Alright, folks, Rusty here. Let’s break down the surf for the next couple of weeks. It’s a bit of a slow start, but we’ve got some serious juice coming in.
The first few days are a bust. Wednesday the 22nd and Thursday the 23rd are blown out with onshore wind. The surf is poor, so don’t bother.
It gets interesting on Friday morning the 24th. The wind goes glassy, and we’ve got a small 3ft swell from the SSW with a long 15-second period. The energy is moderate (714). It’s clean. The swell builds through the weekend, with glassy conditions on Saturday the 25th and a solid 4ft from the SW. Sunday the 26th morning has a 3ft groundswell with a very long 20-second period – that’s going to be a bit straight and tricky at the beach. The water temp is 76°, which is a touch warmer than normal.
The first real standout is Monday the 27th. We’re looking at a 7ft to 8ft SW groundswell, with a 16-second period and glassy conditions all day. The combined energy is strong to very strong (around 3244 in the morning, 3375 in the afternoon). This is excellent, but anything over 8ft is for experts only. Beginners, stay out of the water.
The quality holds through Tuesday the 28th and Wednesday the 29th, with clean 5ft to 6ft SW swell and glassy winds. The energy is strong (over 1000). Thursday the 30th has a rough morning, but it cleans up by the afternoon.
Now, the big one. Monday the 3rd of August. This is a monster. We’re talking a massive 13ft S swell, with a 12-second period and glassy, calm conditions. The energy is exceptional – 8780 in the morning and 9063 in the afternoon. This is only for expert surfers. That size is no joke. It’s a powerful groundswell, so it’ll be wide and breaking straight at the beach. The following Tuesday the 4th of August is still excellent, with 8ft S swell and clean.
The last few days, from the 5th to the 6th of August, the swell drops to 3ft to 5ft, with the energy falling to moderate. It’s glassy, but the waves are smaller.
The standout is Monday the 3rd of August. That’s the session to plan for if you’ve got the skills. Crowds at Black Rocks Jetty can be a problem sometimes, so be prepared. For the rest of us, Monday the 27th of July and Tuesday the 28th of July are the best bets – excellent, clean, and powerful.
Rusty.
