The Lowdown
Alright folks, Rusty here.
Let's look at what’s lined up for us at Guarda do Embau over the next couple of weeks. We’ve got a classic setup here – a river mouth that can really turn it on when everything lines up. Right now, water temp is sitting at 66°, which is pretty much bang on average for this time of year, so no surprises there.
The early part of the week is looking a bit ordinary, to be honest. Wednesday and Thursday see some SE swell, but the wind and conditions are messy. The combined energy is moderate – around 886 and 944 on Wednesday – but with cross and cross-on breezes, it’s just not clean enough to get excited about. Thursday morning has a bit of clean cross-off wind, but the swell has dropped to 5 ft and the energy is down (566), so it’s marginal at best.
Friday and the weekend are flat and poor. Swell barely cracks 4 ft, the wind is all over the shop, and you’ll be battling cross-chop. We’re talking a few days of basically nothing worth paddling for.
Monday the 7th is the first standout. We’ve got an 8 ft S swell rolling in with 10-second periods, and the combined energy is a massive 2271 – that’s strong wave energy. The wind is a gentle cross-off from the SSW, which will keep it reasonably clean. This is a solid, powerful swell, and at that size it’s getting into expert territory. The river mouth should handle it well, but be ready for some juice.
After a bit of a lull, Thursday the 10th brings another good window. The afternoon looks the pick with a clean 6 ft ENE swell (combined energy 565) and nice light cross-off wind. This is a much friendlier size for a good range of surfers, and the conditions should be glassy.
Looking further out, Sunday the 13th shows promise. A clean morning with 6 ft S swell, but the real highlight is the afternoon – combined energy jumps to 1069 and the swell bumps up to 6 ft with light cross breezes. It’s a big build-up, and worth keeping an eye on.
Monday the 14th is another one to circle. The morning has a clean 5 ft SSE swell with a long 12-second period – classic groundswell – and light offshore wind. The energy is moderate (655), but that period will give the waves some real push and shape. A river mouth like Guarda loves that.
After that, the second week trails off into smaller, wind-affected conditions. Tuesday the 15th has a clean morning but only 4 ft, and by Wednesday the 16th we’ve got a 15-second period swell hitting, but the wind is cross and choppy, so it’s a tough call.
Overall: Your best bets are Monday the 7th for the big, powerful surf (experts only), and Thursday the 10th afternoon or Monday the 14th morning for cleaner, more manageable waves. Guarda is a consistent spot, so even if it goes quiet for a few days, it tends to fire back up.
