Mngazi Surf Forecast and Surf Report

Alright, let’s get into it. The forecast window opens with a real beast of a swell hitting Mngazi on the afternoon of July 28th. This is a river break, and it’s inconsistent, so when it turns on, it’s a special thing. The water is sitting at 71°F – a touch warmer than normal for this time of year, which is nice.

That first pulse on Tuesday the 28th is a solid 10ft south swell with a 15-second period – that’s proper groundswell, and it’s packing some serious energy (5867). The combined energy is right up there, but the waves are going to be too big for most. The wind is a cross-on southerly at 9 mph, which isn’t ideal, but the forecast says wind and tide are favorable. Still, for the average surfer, this is a day to watch from the sand. The long period on a south swell lines up well with the optimum direction for Mngazi, which is SE, so the reef and river mouth should be handling it.

Come Wednesday morning, the 29th, the swell drops to 7ft from the SE, but the period drops to 8 seconds – that’s a shorter, weaker swell. The wind is light cross-on. Not great. But then Wednesday afternoon... that’s the standout session of the early window. The swell holds at 6ft from the SE, period still 8 seconds, but the wind goes glassy – 0 mph. It’s going to be clean. The energy is moderate (882), and the forecast says “expect very good surf conditions.” This is the moment. For a break that’s inconsistent, this is the one to circle.

Thursday the 30th through to the end of July and into the first week of August is a long stretch of marginal surf. The swell hangs around 6ft to 7ft, mostly from the SE or E, but the wind is always cross or cross-on, and the scores are low. The energy is moderate, but the conditions are just never quite right. There’s a lot of chop and cross-chop. It’s not a total write-off because the swell is consistent, but you’d be fighting the wind.

Then we hit a gap. From around August 5th, the swell really drops off. The 5th has 4ft and 4ft waves with weak energy (292-317), and it goes to poor or marginal. The 6th sees a new pulse from the SSW with a very long period of 14 seconds, but the height is only 3ft to 5ft, and the wind is cross-on. The 7th and 8th are similar – small, long-period SSW groundswell, but with messy wind. The energy is moderate (408-843), but the size isn’t there for Mngazi to really work. This is a quiet period.

Now, hold on to your board. The 11th of August, Tuesday morning, is a massive call. Another 10ft swell, but this time from the SW with a 17-second period. That’s an incredibly long, powerful groundswell. The combined energy is huge (5422). The wind is light cross-offshore from the ENE. But again, the warning is clear: the swell is predicted to be too big for this break. Mngazi is a river break, and that kind of size and period will make it a washing machine. Only for the most experienced, and even then, it’s sketchy.

The 12th of August, Wednesday, is even bigger. We’re talking 18ft from the SSW with a 12-second period. The energy is off the charts (8866). The wind is light cross. Again, the forecast says it’s too big for the break. This is not a surfing day unless you’re tow-in ready. The river mouth will be a mess.

So, to sum it up: The clear winner is the Wednesday afternoon, July 29th. That’s your window. Glassy, 6ft SE swell, moderate energy, and the break is inconsistent, so when it’s on, it’s a treat. The July 28th and the August 11th and 12th are massive, but they’re too big for Mngazi, so unless you’re an expert with a death wish, give them a miss. The rest of the window is a bit of a slog with marginal conditions. Keep your eyes on the 29th.

Rusty.
