The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up for Guarda do Embau.
Right off the bat, the first few days are a bit of a write-off. We’ve got small, short-period SSE swell bumping into cross or cross-onshore winds, and the energy is weak to moderate at best. Tuesday and Wednesday of this week are just not worth paddling out for. The wait continues.
Thursday morning the 17th we finally get a window. It’s not big—around 3ft from the S with a short 8-second period—but the wind goes glassy. That’s a major positive. It’ll be clean and workable for a beginner-friendly wave. The combined energy is moderate (202), so don’t expect power, but it will be fun. Friday morning the 18th is also tidy with a light cross-offshore breeze and clean surf around 3ft from the SSE. That’s a solid run of small, clean, user-friendly waves.
The standout session in the whole outlook is Monday morning the 21st of September. We’ve got a solid 6ft swell coming from the ENE with a 9-second period, pushing moderate-to-strong combined energy (575). But the real kicker is the wind: glassy and offshore from the SSE. That’s about as perfect as it gets for a river mouth setup. The waves will have some push and shape, but at this size it’s still doable for intermediate surfers, though beginners might find it a bit much. The dawn patrol is going to be worth setting the alarm for.
Water temp is about average for this time of year, so no surprises there.
The second week gets a bit messy again. There are pulses of swell, but wind and chop spoil most of them. The 23rd and 24th have some SSE swell up to 6ft, but cross-shore winds keep it from cleaning up well. Late in the month, around the 28th and 29th, we see a bigger S swell building—up to 8ft on Monday afternoon with very strong energy (1387)—but those are marred by onshore wind and rain. That’s expert territory with poor conditions, so it’s more of a look-and-see situation.
Overall, your best bet is the glassy Thursday the 17th and the standout Monday the 21st. The river mouth won’t be crowded mid-week, but keep your eyes open for others with the same idea on Monday.
Rusty.
