Mohaka River Mouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for the Mohaka River Mouth.

This stretch of the coast is about to go through a real rollercoaster. We’ve got a solid run of swell coming through, but the wind is gonna be a big drama for the first week, so don’t get your hopes up too early. There’s a bit of a gap in quality conditions before we find the real windows.

Right now, the water is sitting at 53°, which is a bit colder than normal for this time of year – you’ll want a good hood and gloves.

Thursday the 13th afternoon kicks off with some small, clean waves at 3 ft from the ESE, with a light cross-off breeze. The energy is weak (139) and the period is short at 8 seconds, so it’s not going to be anything special.

Friday the 14th morning will be even smaller, about 2 ft, but the wind will be glassy. That’s a nice start to the day for a paddle if you’re desperate, but the swell energy is very low (53).

Saturday the 15th morning is where it starts to get interesting. The swell jumps to 5 ft from the ESE, with a period of 9 seconds, and the wind is glassy. The wave energy is building strong (418). This is a genuine standout window for those who can get out early. The wave direction is a bit off the optimum (S), but the clean conditions will make it worth it. Expect crowds to be possible though.

From Saturday afternoon, things get ugly quick. Sunday the 16th brings strong onshore winds from the SSW cranking at 30 km/h, making a mess of things. The swell drops to 4 ft and then 3 ft, but it’s all junk.

Monday the 17th sees a big pulse of swell – 10 ft from the S! But the wind is a fresh cross-on at 25 km/h, so it’s going to be a choppy, blown-out mess. The combined energy is huge (2565), but for surfing, it’s a write-off. This is more kite-surfing territory. That size is for experts only, anyway.

Tuesday the 18th and Wednesday the 19th stay rough with strong cross-on winds and big swell (6 ft to 8 ft). The energy stays high (791 to 2056), but the quality is poor.

The wind finally turns in our favour on Thursday the 20th morning. The swell will be a clean 6 ft from the SSE with a light cross-off breeze from the west. The energy is moderate (530), and the waves should be clean and fun. This is another solid, short window.

Friday the 21st morning is glassy with a 4 ft SSE swell, and the energy is climbing (466). Nice and clean for a morning session.

Friday the 21st afternoon brings a very long period swell of 16 seconds at 4 ft from the SSE. The energy is high (772). This is a proper groundswell. At a river mouth sandbar, that long period can make things a bit straight and tricky, but it’ll have serious push. The wind is light and cross-shore.

Saturday the 22nd morning is still clean with a cross-off breeze and a 3 ft swell from the S, with a very long period of 15 seconds. The energy is moderate (374). It’s small but clean, and that long period will give it shape.

After that, the swell fades away into the second week. From Sunday the 23rd onwards, we’re looking at tiny waves, mostly under 3 ft, with a mix of clean and glassy conditions but nothing with any real power. The best of the second week looks like Monday the 24th morning with a 2 ft SE swell and offshore wind, but it’s just too small to get excited about.

The real standouts are Saturday the 15th morning for the glassy conditions on a decent 5 ft ESE swell, and Thursday the 20th morning for the clean cross-off on a solid 6 ft SSE swell. Get on those.

Rusty.
