The Lowdown
Alright, Rusty here, givin' you the lowdown for your local spot.
We got a slow start, then a big pulse of south swell later on. The winds are gonna be the story, so pick your sessions.
First real chance to get wet is Saturday morning, August 15th. There's a 5ft swell from the SSE with a 12-second period, and the energy is pumping at 1208. That's a proper groundswell, and at *Guarda do Embau*, a river mouth, that long period can really groove. The wind is a light ENE cross-on at 6 mph, so it's a bit bumpy but doable. Water temp is feeling about normal for the time of year.
The weekend and early next week are kinda messy. We have size – 6ft to 6ft on Sunday and Monday – but the north wind is howling at 12 to 16 mph, chopping everything up. Tuesday morning the 18th looks cleaner with an offshore breeze, but it's still just a 6ft NE windswell with a short 8-second period. You can surf it, but it's nothing special.
We hit a real flat spell from Wednesday the 19th through Friday the 21st. The swell drops below 3ft, and conditions are pretty ordinary. Friday morning the 21st is glassy with a tiny 3ft, 7-second wave, but it's barely a ripple.
Now, here's the good stuff. Saturday the 22nd morning, a new SSW groundswell rolls in at 5ft with an 11-second period. The wind is a light north offshore, keeping the faces clean. The energy is moderate at 530. This is a solid, fun session.
The real standout – the one you need to plan for – is Sunday the 23rd. The swell jumps to 8ft from the south with a super long 15-second period, and the energy is massive at 5251. This is serious, heavy water. The wind is a moderate cross-shore from the SSW, so it's not pristine, but at that size and period, the river mouth at *Guarda do Embau* will funnel that energy into some beasts. But listen, 8ft is big. This is for experts only. Beginners, stay on the beach and watch. It's too dangerous.
The swell hangs around Monday the 24th and Tuesday the 25th, dropping from 6ft to 5ft but keeping that long 12 to 13-second period and a ton of energy (1014 and 1122). Tuesday morning the 25th looks the best of those days, with a light offshore breeze and clean conditions.
After that, it fades back into small, mixed-up dribble through the end of the month and into early September.
So, the first week is a wash. But if you can wait, the 22nd and especially the 23rd of August are your best shots at some real power. Don't be a hero on the 23rd if you're not ready for it.
Rusty.
