The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Irmas/Leftpoint. I’ll be straight with you – this stretch of the next 16 days is a real mixed bag, and most of it is a write-off. We’ve got a decent amount of swell energy coming through, but the wind is just killing the vibe.
First up, we’ve got a bunch of days with nothing worth paddling out for. Friday the 24th through Monday the 28th of July are all showing poor surf conditions. The wind is hammering from the ENE, mostly cross or cross-shore, and it’s strong. We’re talking 18 to 28 mph winds creating a messy cross-chop. The swell is there, but it’s short-period stuff, 7 to 12 seconds, and the wind just ruins any chance of a clean face. Not worth getting wet.
Now, there’s a small window on Tuesday the 28th of July, afternoon. The wind shifts to a cross-offshore from the NNE at 22 mph, and the wave state cleans up. The swell is 7 ft from the East at 12 seconds. That’s a bit of a highlight, but it’s still marginal. It’s a reef break, so that longer-period groundswell will actually shape up nicely here, but it’s also a bit hefty for beginners. The crowds are *sometimes* there, so you might have some company but not a zoo.
Wednesday the 29th of July morning is a real standout for the brave. We’re looking at a solid 12 ft swell from the ENE, with a period of 11 seconds. That’s a lot of power. The wind is cross from the NE at 12 mph, so it’s moderate chop. This is expert territory only – 12 ft is beyond big, and the energy is intense. If you’re not a seasoned charger, stay on the beach. The afternoon switches to onshore and it’s gone.
After that, from Thursday the 30th of July all the way through to Saturday the 8th of August, it’s a long, bleak run. The wind is relentless from the ENE, mostly cross or cross-onshore, and the wave state is either lumpy, choppy, or just messy. The swell drops off and picks up again, but it’s never clean. Even the bigger pulses on the 5th and 6th of August (7 ft and 5 ft) are ruined by the wind.
So, the best on offer? That Tuesday afternoon the 28th of July is your most realistic shot for a decent, clean-ish session, but it’s not a classic. The real standout is Wednesday morning the 29th of July, but that’s for experts only. If you’re not in that boat, you’re looking at a long wait.
Rusty.
