The Lowdown
Hey, Rusty here. Let’s break down the outlook for Guarda do Embau, a river break that’s open to the swell. Gonna be a real mixed bag over the next couple weeks, so listen close.
Water temp is 66°F, right where it should be for this time of year – nothing unusual.
We start slow. Sunday, August 16th, first waves are 7ft out of the ENE, but it’s a weak 8-second windswell. Bumpy cross-shore wind, combined energy reading 1031 – moderate push but messy. Morning is slightly better, but still just marginal.
Monday (Aug 17) stays similar with 6ft ENE windswell. Morning is clean with offshore wind, but energy is low – only 369. Few lined-up runners for the keen ones. Afternoon gets hammered by 19 mph cross-shore, so hit it early.
Tuesday (Aug 18) – 6ft NE windswell, still short period. Energy climbs to 779 – moderate. Morning stays clean, afternoon has a light cross breeze. Not firing, but more user-friendly.
Wednesday morning (Aug 19) – surf drops to 4ft ENE – small, but the wind goes glassy. Combined energy is a weak 183, so small and clean waves. Perfect for a longboard or a beginner. Dawn patrol gold.
Thursday (Aug 20) through Friday (Aug 21) – swell dries up. Knee-to-waist high slop, weak energy under 200, and mostly choppy. Not worth the paddle.
Saturday (Aug 22) – new S swell starts filling in. Saturday morning we’ve got 5ft S at 10 seconds – energy 956 – moderate and building. Light cross-shore is okay. Afternoon hits 6ft S with energy up to 1284, but it’s cross-onshore and choppy. Power’s there but the surface is rough.
Now… Sunday, August 23rd – this is the one. Morning is 8ft S at 9 seconds, combined energy 934, and it’s glassy. Completely flat water. This is the standout session. At 8ft it’s pushing into expert territory, but the river mouth will handle it beautifully. The afternoon gets to 8ft S at 11 seconds – long-period groundswell, energy 1515 – powerful but cross-onshore messes it up.
Monday (Aug 24) – 8ft S at 11 seconds, combined energy a massive 2150 – strong to very strong. Morning is clean offshore. This is solid, expert-level surf. Not for the learning crowd.
Tuesday (Aug 25) – drops to 4ft SSE groundswell at 10 seconds, glassy in the morning. Clean and fun.
Wednesday (Aug 26) – 5ft SSE with a very long 12-second period. Morning stays clean. This long-period groundswell will line up nicely along the river bank. Energy is 833 – moderate but quality.
Thursday (Aug 27) – back to short-period 6ft ENE windswell. Morning is clean, energy 856 – okay, not special.
The last week, from Friday (Aug 28) onward, is smaller, choppier, and weaker. Not much to chase except one or two clean mornings that produce small waves.
Best bet: Lock in Sunday morning, August 23rd. That’s your clean, solid, glassy session. Don’t miss it.
Catch ya out there,
Rusty
