Mohaka River Mouth Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s coming up at Mohaka River Mouth. It’s a sandbar set-up that needs a solid S swell to fire, and right now, we’ve got a bit of a waiting game on our hands.

The next week and a bit is pretty grim. From now through to the end of next week, the surf is small, messy, or just plain poor. There’s a long stretch of nothing worthwhile. A few tiny pulses show up but with onshore or cross winds, and weak energy (values in the low teens to low 30s), there’s nothing to get excited about. Even the bigger lump on Monday the 9th (about 4ft, ESE) stays clean but lacks any punch. It’s a frustrating start.

Things start to look up around Sunday the 13th when a proper S swell pushes through. That morning we’re looking at around 6ft from the S, with a period of 11 seconds, and clean conditions under a cross-offshore WNW breeze. The combined energy hits 893 (moderate) – it’s a decent pulse but still not quite the standout. The wind gets a bit cross-shore in the arvo, so the morning window is your move.

Now, the real standout comes on Monday the 14th. This is the one to circle. Overnight the swell builds to about 8ft from the S, with a long period of 13 seconds – proper groundswell. The combined energy is massive at 1968 (very strong). And here’s the kicker: glassy conditions with a light NNW breeze. It doesn’t get much cleaner than that. That said, at 8ft, this is expert territory. The long period groundswell is best handled at the river mouth – it’ll set up nicely there, with those long gaps between sets making paddle-outs a bit easier. This is easily the best on offer across the whole outlook. Crowds are possible here, so expect some company if you go.

After that, Tuesday the 15th keeps the fun going with about 4-5ft S swell at 12 seconds, clean under a cross-offshore NW breeze, energy at 558 (moderate). It’s a notch down but still very good. Friday the 18th sees another solid S swell – around 6-7ft in the morning, clean with a light offshore N breeze, and energy at 849. That’s another good morning. The following Saturday the 19th gets big again (around 10ft S, 10 seconds) but with a stronger WNW cross-offshore – that’s big and punchy, definitely for experts only, and the shorter period means it’ll be a bit more walled up. Energy at 1584 (strong), but not quite as clean or lined-up as Monday the 14th.

Water temp is about average for this time of year, so nothing to worry about there.

Alright, that’s the rundown. The Monday the 14th morning is your absolute standout – mark it in your calendar. A close second is the Friday the 18th morning. Get amongst it.

Rusty.
