The Lowdown

Alright, Rusty here, let's have a look at Bali Bay (Glen Reef). The forecast shows a bit of a mixed bag over the next couple of weeks, but there are some definite windows to get excited about.

The first few days of the outlook are pretty lackluster. The swell is small, around 2 ft to 3 ft, and the wind is messing it up. Tuesday the 8th and Wednesday the 9th are just not worth paddling out for, with cross-shore breezes and a weak, messy energy reading. Thursday the 10th morning sees a jump in size to 8 ft, but that 15 km/h SSE cross-shore keeps things choppy, and the energy is still moderate. It's a bit of a frustrating start.

Things start to look a little more promising on Friday the 11th morning. The wind is clean and cross-offshore, with a 6 ft swell from the WSW at 12 seconds. It's not huge, but it's clean, which is a big plus. The energy is moderate. Saturday the 12th and Sunday the 13th also have some clean morning windows, but the wind gets too strong to be really enjoyable. Sunday afternoon the 13th has a 8 ft SSW swell, but a short period of 9 seconds, and the wind is light, so it might be a bit average.

The standout period is shaping up for the middle of the second week. That Tuesday the 15th afternoon is a real eye-opener. A solid 7 ft WSW swell is rolling in with a very long period of 24 seconds. That's some serious groundswell energy, with a massive energy reading. The wind is a fresh cross-shore, so it's not perfect, but the power of that swell is undeniable. This is a spot for experienced surfers only.

Then, hold on to your board. Wednesday the 16th is a monster. The swell is predicted to be 16 ft from the WSW with a 17 second period, and the energy is off the charts. The wind is light and clean on the morning. The notes say it's too big for this break, and I agree. This is big, serious, powerful surf. The following Monday the 21st and Tuesday the 22nd of September also see solid 10 ft to 15 ft swells, but again, these are likely to be too big for a comfortable session at Bali Bay, especially for anyone who isn't a seasoned expert.

For the best of the manageable, clean surf, I’d be looking at the morning of Friday the 11th. It's not the biggest, but the clean conditions and consistent 6 ft swell from the WSW will give you some fun, clean waves. The other standout is the morning of Sunday the 20th, with a 6 ft, 14-second groundswell from the WSW and very light winds. The energy is moderate, but the clean conditions and solid swell make it a great call. Crowds are possible here, so keep an eye out for company.

The water temperature is about average for this time of year, so no complaints there.

Rusty, signing off.
