Monabe Rivermouth Surf Forecast and Surf Report

Right, let’s have a look at the only spot on the menu here. It’s Monabe Rivermouth, and it’s a real tricky one. This break is a rivermouth, rarely breaks, and is very sheltered. It’s not the kind of place you can just rock up and expect waves. The next 16 days have a few moments, but you’ll need to be patient.

The first decent chance comes Monday morning, 24th August. The wind is glassy, and there’s a clean 1.0ft swell from the SE. The period is a very long 16 seconds, which is proper groundswell energy. The combined energy is 654 (moderate), so there’s some push. For a rivermouth, that long period can really line up, but it’s still only knee to waist high. Not a standout, but a quiet morning session might be on.

The real standout is Wednesday morning, 26th August. This is the best of the run. The wind is dead calm, glassy, and the swell is a solid 12ft from the S with a 14-second period. The combined energy is a massive 4527 (strong). This is serious, powerful groundswell. For a rivermouth, that long period will make it hollow and fast, but this size is only for experienced surfers. It’s too big for beginners. The water temp is about average for the time of year.

Thursday morning, 27th August, sees the swell drop to 7ft from the SSE, but the wind is cross-onshore, making it lumpy. Not great.

Friday morning, 28th August, is another good call. The wind goes glassy again, and there’s a 8ft S swell with a 10-second period. Combined energy is 1310 (moderate). This is a much more manageable size, and the glassy conditions will make it clean. A solid option for a Friday surf.

After that, the run gets more ordinary. There’s a gap of smaller, poor surf through the weekend and into the start of the following week.

Then, looking ahead to Thursday morning, 3rd September, there’s a promising one. Offshore wind from the NNE, combined with a 5ft SE swell, but the period is a very long 18 seconds. Combined energy is 2379. That’s proper groundswell, and the offshore wind will groom it. For a rivermouth, that long period and direction is a good match. It’s a bit far out, so less certain, but worth keeping an eye on.

The rest of the second week gets messy with strong winds and rain, so it’s mostly a write-off.

So, the best on offer is Wednesday morning, the 26th of August, for the big, powerful groundswell, but only if you’re experienced. The most accessible, clean session is Friday morning, the 28th of August.
