Monabe Rivermouth Surf Forecast and Surf Report

Alright, Rusty here, let’s have a look at what’s on offer for Monabe Rivermouth.

Straight up, the first few days are a bit of a letdown. There's some small swell around, but it’s nothing to write home about. We kick off on Wednesday, September 2nd with a bit of SSE swell around 4ft and glassy conditions in the morning – the water is a touch warmer than normal for this time of year at 85°. But honestly, the energy is weak and the conditions are just ordinary. That afternoon it turns onshore and messy, so you’re not missing much.

Thursday the 3rd and Friday the 4th stay in that same mediocre zone – small, short-period swell, rain around, and just average wave quality. Not worth paddling out for unless you’re desperate for a splash.

Now, there’s a gap of poor to ordinary surf right through until Sunday the 6th. That’s when things start to get interesting. Sunday morning sees a solid 13ft easterly swell roll in, with a combined energy of 2319 (moderate-strong) and clean conditions thanks to a cross-offshore breeze. That afternoon is even better – still 13ft, offshore wind, and glassy. This is the first real standout of the forecast period. It’s big, though – over 8ft – so this one’s for the experienced crew only.

Monday the 7th stays solid but drops a little, with 10ft ESE swell and clean conditions in the morning. Good, but not the peak.

The true highlight of this whole run is Tuesday the 8th. We’re looking at 15ft ESE groundswell with a period of 11 seconds, and the combined energy is a hefty 4688 – that’s strong. Offshore winds from the north, glassy conditions, and excellent surf for those who know what they’re doing. The swell direction is a bit east of the optimum, but the quality is undeniable. This is the day. Crowds are sometimes an issue here, so get in early if you can.

Wednesday the 9th still has decent 7ft swell and glassy conditions, but it’s a step down. From Thursday the 10th through to Monday the 14th, it’s a mixed bag of onshore winds, smaller swell, and poor to ordinary conditions. A few windows of glassy weather, but the swell is weak and short-period.

Then, another big pulse hits on Tuesday the 15th – a massive 13ft ESE groundswell with a very long period of 15 seconds. Combined energy is a whopping 6938. That’s expert territory, and the morning looks clean with a slight cross-offshore breeze. That afternoon gets too messy with onshore wind, but the morning session is a ripper for the bold.

Wednesday the 16th and Thursday the 17th both have 10ft easterly groundswell, glassy mornings, and offshore winds. Quality waves for experienced surfers, but the swell is a bit east of the sweet spot.

All in all, the standout days are Tuesday the 8th and Tuesday the 15th – both have big, powerful groundswell, clean conditions, and serious energy. Mark your calendar.

Rusty.
