The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Guarda do Embau over the next couple of weeks.
We’re starting off with a bit of a slow burner. The first couple of days offer some small, clean waves, but nothing to write home about. The real story builds up towards the end of the first week and into the second, with a couple of windows that could be really special.
Tuesday morning the 18th gives us a little 5ft wave from the ENE with a short 8-second period. The wind is a clean cross-off, so it’ll be a fun size for a beginner-friendly spot like this river mouth. The water is sitting at 66°F, which is bang on average for this time of year. The combined energy is weak (298), so don’t expect any punch, but the conditions are right.
The rest of the week into the weekend is pretty ordinary. Wednesday and Thursday are small and messy. Friday morning the 21st has a tiny 3ft wave with a light cross-off and glassy morning conditions, but it’s just not got enough juice. Then we hit a bit of a dry spell until the swell picks up again.
Now, the first standout. Saturday the 22nd sees a jump in swell, but the morning is a bit of a write-off with a 7ft S swell and a cross wind kicking up some chop. The energy is moderate (1206). However, Sunday the 23rd morning is the better call. We’ve got a 6ft swell from the S with a longer 11-second period, giving it a bit more shape. The wind is light and variable, almost glassy, so it’ll be clean. The energy is moderate (674). This is a solid window for a longboard or a fun mid-length board.
The next standout comes on Monday the 24th. This is a big one. The swell jumps to 8ft from the SSE, with a very long 14-second period. The combined energy is strong (2408). This is serious groundswell. The morning wind is light and cross, keeping it manageable. For a river mouth setup, that long period means the wave will be lined up and powerful, but it could also be a bit too straight for the bank. This is definitely for experienced surfers only. The size is pushing into expert territory.
After that, the swell drops back down through the rest of the week. Tuesday the 25th has a drop in size with a strengthening wind, so it’s a pass. The following week has some clean, glassy mornings, like Friday the 28th morning with a small 4ft NE swell and glassy conditions. Then Saturday the 29th is a real gem for beginners or small-wave enthusiasts. The morning is dead flat calm and glassy, with a 5ft SSW swell. The energy is moderate (482). It’s a perfect window for a long, clean session on the inside.
Towards the end of the run, Monday the 1st of September sees a bit more size, but the conditions are marginal with light rain and onshore wind. The 7ft SSW swell on the 31st of August morning is a powerful one (1085 energy), but the onshore wind makes it a tricky call.
So, to wrap it up: the best bets are Sunday the 23rd morning for a clean, fun 6ft groundswell, and Monday the 24th morning for the serious, powerful 8ft SSE groundswell for the experts. The Saturday the 29th morning is your best bet for a small, glassy longboard session.
Rusty.
