Morro Negrito - Rivermouth Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about Morro Negrito - Rivermouth. It’s a slow start, but there’s some real gems hidden in this forecast if you’re willing to wait for the glassy mornings. The water is about 86°, which is a touch warmer than usual for this time of year, so it’s nice and comfortable.

Right off the bat, Friday the 28th of August is tiny. We’re lookin’ at 1ft of SW swell with a long 19-second period – that’s proper groundswell, but the combined energy is only 159, so it’s a weak push. The morning is dead calm, glassy as glass. You could have a laugh on a longboard. The river mouth will handle that long period nicely. Afternoon has a risk of storms, but still glassy – same small, ordinary waves.

Saturday the 29th morning is where things start to look up. Clear skies, glassy, with 2ft of SW swell and a 16-second period. The energy jumps to 299 – that’s moderate now – and the comment says “expect good surf conditions.” The wind is offshore from the SW, dead calm. The swell direction is perfect from the optimum SW. It’s still small, but clean and fun. Crowds can show up sometimes, so get in early.

Sunday the 30th morning is similar – 2ft SW, 14-second period, glassy with a light WSW breeze. Energy’s 226. Another solid small-wave morning. Afternoon gets cross-onshore and stormy, so quality drops.

Monday the 31st morning is back to 2ft, 13-second period, glassy but weak at 163 energy – ordinary. Afternoon turns onshore and poor.

Tuesday the 1st of September and Wednesday the 2nd are much the same: around 2ft, glassy mornings but weak energy, afternoons chopped up. Not worth getting excited about.

Thursday the 3rd morning is 1ft, 16-second period, glassy, but only 135 energy – very weak.

Now, Friday the 4th of September morning is a standout again. We’ve got 2ft of SW swell, 18-second period, and the energy jumps to 362 – solid moderate. Glassy conditions with a light SSE breeze. “Expect good surf conditions.” That long-period groundswell will push clean lines down the river mouth. Crowds are possible, but it’s worth it.

Saturday the 5th of September morning gets a touch bigger at 3ft, but the wind swings cross-onshore from the WSW at 10 km/h, with storm risk. Energy is high at 456, but quality is only marginal. Not the best.

Sunday the 6th of September morning is cross-on and marginal, but the afternoon turns glassy again with 2ft, 15-second period and 245 energy – that’s a solid second-window for a clean session. “Expect good surf conditions.”

Monday the 7th and Tuesday the 8th mornings are glassy but small – around 2ft. Tuesday the 8th morning has an 18-second period and 300 energy, so it’s got a bit more grunt. Good for a river mouth.

Wednesday the 9th morning is a cracker – 2ft SW, 17-second period, glassy, 328 energy. “Expect good surf conditions.” Another standout morning. Swell direction is ideal.

Thursday the 10th is solid – both morning and afternoon are glassy with 2ft, 15-second period and around 250 energy. Two clean sessions in one day – that’s a treat.

Friday the 11th morning is glassy again with 2ft, 16-second period and 268 energy – “expect good surf conditions.” The run of clean mornings is the real story here.

Saturday the 12th of September drops off – cross-onshore, poor conditions, small swell.

So, the standout windows are the mornings of Saturday the 29th of August, Friday the 4th of September, Wednesday the 9th of September, and the whole day Thursday the 10th of September. The swell never gets above 3ft, so it’s perfect for all skill levels. No big scary waves, just clean, fun lines when the wind plays ball.
