The Lowdown
Alright mates, Rusty here. Let’s break it down.
We’ve got a solid push of south-southeast groundswell hitting Guarda do Embau this week. That 14-second period swell brings real energy, long lines, and that deep-water punch. The combined energy sits at 926 (moderate wave energy) – enough to get you moving.
Wednesday morning the 12th kicks things off. Swell is 6ft from the SSE with a 12-second period, and a light north wind holds it cross-offshore. Clean, workable, and the water temp is about average for this time of year. A proper start for intermediate surfers. Beginners might find 6ft a bit much.
Thursday morning the 13th is the real standout. Swell holds at 6ft, period jumps to 14 seconds, combined energy hits 1331 (moderate wave energy), and the wind drops to a 3 mph south-west cross-offshore – almost glassy. This is excellent surf. The river mouth will be lining up nicely. Expect good shape and longer waits between sets.
Friday the 14th through Sunday the 16th sees the swell hang around 4ft to 6ft, but the wind turns light cross-onshore and the period drops to 8 seconds. That’s windswell territory – less grunt, more chop. Not the best, but still surfable for a paddle.
Next week, from Monday the 17th onwards, the wind gets stronger and the swell direction shifts east-northeast. The 17th afternoon sees 8ft from the ENE with a fresh 18 mph cross-shore. That’s bumpy, and at that size, it’s for experts only. The combined energy jumps to 1472, but the quality is marginal. This setup starts looking more like a kite day than a clean surf day.
There’s a stretch of poor conditions from the 18th to the 24th. Winds are moderate to fresh, cross or cross-on, and the swell drops to 1ft to 5ft with poor energy. A few days of small, weak, messy surf. Not much to write home about.
Then, on Tuesday the 25th, we get a second pulse. The morning shows 5ft from the SSE, 13-second period, with a 3 mph west wind and glassy conditions. Combined energy is 914 (moderate wave energy). That’s a clean, punchy morning session. It’s a week and a half out, so keep an eye on it, but it looks promising.
The 26th and 27th bring size back to 7ft to 8ft, but the wind is moderate cross-shore from the south-west and the period drops to 8 seconds. That’s a lot of water moving around without much shape – more for the experienced crew, and only if the wind plays ball.
Best of the outlook: Thursday morning the 13th and Tuesday morning the 25th. Both are clean, solid groundswell with light winds. The 13th is the clear winner.
Rusty.
