Jetty Surf Forecast and Surf Report

Alright, let’s have a look at what’s on the cards for the next couple of weeks. To be straight with you, it’s a pretty quiet stretch. The first real chance of any waves doesn’t even show up until Friday morning the 11th of September, and even then, it’s tiny—knee-high at best. We’ve got a long wait ahead.

Friday 11th September kicks things off at Jetty. We’re looking at a tiny 2 ft swell from the south, with a short, weak 6-second period. Combined swell energy is a paltry 40 (weak). The morning sees a light offshore breeze from the north, which will keep the surface clean, but honestly? There’s barely enough water moving to paddle. It’s a poor surf call.

Saturday is even smaller, with 1 ft from the southeast. The period stretches out a bit to 9 seconds, but that’s a long period for such a weak, tiny wave. It won’t do much. Winds are cross-onshore or onshore, so it’s a write-off.

Sunday 13th sees a slight bump to 3 ft from the south-southeast, but the period is a snappy, weak 6 seconds. Combined energy is still low at 69. With a light cross-shore breeze, it’s small and a bit bumpy. Not worth suiting up.

Monday 14th brings a clean morning with a moderate north offshore wind at 25 km/h. The swell is small, 2 ft from the south-southeast, with a period of 6 seconds (energy 46). The offshore wind is a nice touch, but the wave height just isn’t there. You’d be scratching for a ride.

We then go through a mid-week slump. Tuesday through Thursday (15th to 17th) are all tiny, with swell heights between 0.5 ft and 2 ft. The energy is very low (15-42). The wind is messy. There’s nothing doing.

Then, Friday 18th September—the afternoon shows a bit of life. The swell picks up to 4 ft from the east with a 7-second period, and the combined energy jumps to 161 (moderate). However, it’s a cross-shore wind of 25 km/h, so expect some cross-chop. Still, it’s the first time we’ve had any real push, but the wind will ruin it. It’s still a poor surf call.

Saturday 19th has a similar 4 ft from the east-northeast (6-second period, energy 168) but again, cross-shore winds and a bit of chop. Not clean.

Sunday 20th to Monday 21st return to tiny, clean waves under offshore winds, but we’re talking 1 ft to 3 ft. You could maybe find a knee-high runner if you’re desperate.

Now, Tuesday 22nd September is the best shot in the entire outlook. The morning brings 4 ft from the east-southeast with an 8-second period, and the combined energy is a solid 159 (moderate). Yes, the wind is cross-shore at 25 km/h, which puts a bit of chop on it. It’s not perfect, but this is the peak size we get. The afternoon is similar but cross-onshore, so aim for the morning. Crowds at Jetty can happen, and being a breakwater setup, it’ll hold that east swell okay.

After that, the size drops back. Wednesday 23rd is a windy, choppy mess with 3 ft and strong winds (35-40 km/h). Thursday 24th through Saturday 26th sees a return to clean conditions under strong offshore or cross-off winds, but the swell is mostly 1 ft to 3 ft. On Saturday 26th, a 4 ft south-east groundswell rolls in with a very long 12-second period and combined energy of 346 (strong), but the wind is a stiff 30 km/h cross-off. That groundswell will be powerful, but the wind will make it a battle and it’ll likely be a straight close-out at a beach break. Best left for experts, if anyone even goes.

Overall, this is a genuine flat spell. The swell window just isn’t open. There’s no standout day worth circling on the calendar. Tuesday the 22nd gives you the biggest waves, but the cross-shore chop will spoil the party. Don’t get your hopes up; the run of poor conditions is pretty normal for this area when it goes quiet.
