Monabe Rivermouth Surf Forecast and Surf Report

Alright, grab your board and let’s look at what’s coming up for the Monabe Rivermouth area.

The next week and a half is pretty quiet, honestly. There’s not much doing. We’ve got a bunch of days with tiny, weak surf, and the wind, while often glassy, just isn't lining up with any real swell. It’s a bit of a snoozer. But hold on, because the back half of this outlook is where things get interesting. We're looking at a stretch that has the potential to be something special, if you're an experienced surfer. Just keep in mind, this rivermouth break is rare, and it's unpredictable - it doesn't break often, so when it does, you gotta be ready.

The first real sign of life is on the morning of Friday the 21st of August. It’s not epic, but there’s a pulse of swell showing up at around 3ft from the south with a 9-second period. The combined energy is weak, so it's just making the water move. The wind is glassy and it’s surfable, but it's not going to be a day to write home about. This is more of a “get your wetsuit on and get some practice” kind of session.

Then we go quiet again. From the 22nd through the 23rd, we're back to tiny ankle-slappers with weak energy readings. Not worth the paddle.

Now, hold on to your leash, because things start to get real on Monday the 24th. The morning brings a solid groundswell from the southeast, pushing 5ft with a 16-second period. The energy is moderate, but it’s a taste of what's coming. The wind is glassy, which is a huge plus, but the report says the conditions are just "ordinary." It’s building.

But Tuesday the 25th is when it truly kicks off. We’re looking at 8ft of southeast swell with that long 16-second period, and the energy is strong. The wind is glassy early, too. Now, at this size, it's getting a bit too big for beginners, and you need to know what you're doing out there. This is where it gets exciting.

Then, it just gets bigger and better for the experts. Wednesday the 26th sees the swell jacking up to 11ft in the morning, with a 16-second period and huge energy. The wind is completely calm, which is going to make for some absolutely clean, epic conditions at this river mouth. The afternoon only gets better, pushing 13ft with a 17-second period and incredible energy. This is the standout period for true chargers. With a period that long, the river mouth and point setups are going to be handling it best, it might be a bit wonky at a pure beach break.

Thursday the 27th keeps the size up, with 15ft of south-southeast swell in the morning. The energy here is very strong. The wind is offshore and light, so the sets will be holding their shape. It's still expert-only territory. This is a day for serious boards and serious nerves.

Friday the 28th is still pumping, with another 13ft of swell. The wind clocking around to a cross-offshore in the morning and offshore in the afternoon, keeping things clean. The energy is still very strong. This is another cracker of a day for those who are comfortable charging heavy water.

The weekend is still on. Saturday the 29th brings 10ft waves with the energy still strong. The morning is glass, a perfect time to get out before the wind turns onshore in the afternoon. Sunday the 30th looks very similar—10ft and glassy in the morning, but the wind is more onshore later in the day.

We’re still in the thick of it on Monday the 31st, with 10ft and glassy conditions in the morning, but the swell is starting to ease back. Then into September, things start to trend down. On Tuesday the 1st, we’ve got 6ft in the morning, still with decent energy. The following Wednesday, the 2nd, looks like a smaller, but still fun, 7ft to wrap things up.

So there you have it. A long stretch of nothing, and then a serious window of powerful, long-period groundswell. If you’re not an expert, this is your warning to stay on the beach and enjoy the show. The standout days are the 26th and 27th of August, with that huge, clean, glassy swell. This is promising, but with a long-range forecast like this, you gotta keep an eye on it—things can always change.

Catch you in the water.
