J-Bay Surf Forecast and Surf Report

Alright, Rusty here again. Let's talk J-Bay in numbers you can feel.

First off, the water is freakishly cold right now. We're talking about a massive 9°F below the norm for this time of year. At 55.9°F, you’ll want a pretty thick steamer, particularly for that first session on the 20th. Now, the good news is we’ve got a solid run of swell coming, but there are plenty of trade-offs along the way.

We kick things off on Thursday the 20th afternoon with a hefty 11.5ft SW swell. The energy is big, a reading of 4886, but the wind is cross from the SSW at 9 mph, putting a slight chop on it. It’s big enough that only experienced surfers should be looking at it. The overall forecast is pretty marginal, so don't expect perfection. Friday morning the 21st is still hanging in at 8.2ft SW, but an onshore easterly at just 3 mph won't do it any favors. That one is only a slight breeze, but it’s coming from the wrong direction causing little ripples.

Saturday the 22nd cleans right up with a strong offshore WSW breeze. However, it's howling at 28 mph in the morning. The swell is still a chunky 8.2ft SW, but that kind of wind, even offshore, is going to be punishing. The afternoon eases to a still-stiff 19 mph. It's clean, but is it fun? Probably not.

Now, Sunday the 23rd is a big step in the right direction. Morning glass-off conditions with an 8.2ft SW swell and a solid 11-second period, and a combined energy reading of 1764. The comment says “excellent for experienced surfers,” and I’d agree—that’s the best window of this first block. No crowds mentioned, but at a spot like this on a Sunday morning, don’t be surprised if there are a few others with the same idea. The afternoon gets a little lumpy with onshore wind, but the morning is the clear standout.

Monday the 24th keeps the quality up with clean offshore cross-off winds and a nice 6.6ft SW swell. Another morning session to circle. The back half of the week sees a building swell with a very long 14-second period from the SW on Tuesday the 25th, hitting 9.8ft. This is a groundswell, and at J-Bay, that long period will wrap beautifully down the point, though a light cross-shore wind might put a tiny wrinkle on the face. The energy is seriously pumping at 3427.

We drop off for a few days there from Wednesday the 26th. The swell drops to 4.3ft to 6.9ft with onshore winds and poor conditions, including the 28th Friday afternoon. There is a glassy window on Thursday the 27th afternoon with a tiny 4.3ft S swell, but it’s small and weak with an energy of only 826, so not much to get excited about.

The real standout, the one I’d be circling on the calendar, is Thursday the 3rd of September. Look at this: morning brings an enormous 18.0ft SW swell at a 14-second period. Combined energy is a staggering 11949. The description calls it “exceptional for expert surfers” with a top score. The wind is a light offshore cross-off from the SW at only 9 mph. That is a world-class J-Bay day for the big-wave chargers only. Friday the 4th of September is almost as good with a 14.8ft SW swell, glassy conditions, and energy readings of 9878. These two days are a month away, so a bit of long-range hype, but the signal is incredibly strong. Expect periods of these waves to be very long, making paddling out easier between sets, but the wave faces will be huge and demanding only expert skill. This is the one.
