The Lowdown
Alright, friends, let's take a look at the next couple of weeks out at Steamer Lane-The Slot. This is a solid reef setup, very consistent, and it's fairly exposed to the swell, so it's always got a bit of a pulse. The water temp is around 60°, which is about normal for this time of year, so no need to dig out the thickest wetsuit just yet.
Right now, we're in a bit of a lull. The first few days are pretty flat and average. Sunday the 30th and Monday the 31st are offering some small, marginal waves with a SSW swell, but the wind is mostly cross-onshore, making it choppy and messy. Not worth paddling out for. Tuesday the 1st of September is even smaller, and Wednesday the 2nd, while glassy in the morning, only has tiny 2 ft waves. It's a quiet start, so you might as well save your energy.
Now, things start to get interesting by Thursday the 3rd of September. The morning shows a bit of life with a clean 3 ft SSW groundswell, period around 19 seconds. That's a long-period swell, which means better shaped waves and more grunt, but it can make the sets a bit inconsistent. The wind is light and onshore, so it's not perfect, but there's a pulse. The energy is moderate (601). Friday the 4th of September morning is similar, with a touch more size at 4 ft, but again, the wind isn't doing us any favours.
Finally, the standout window arrives. Saturday the 5th of September is the pick of the first week. The morning is glassy, with a clean 3 ft SSW swell, a period of 16 seconds, and moderate wave energy (676). The forecast suggests very good surf conditions, and with that glassy wind, the Slot will be clean and lined up. This is a solid, fun-sized day for a reef. The afternoon goes cross-onshore, so get out early.
Sunday the 6th of September morning is also looking tidy with another glassy session and a 3 ft SSW swell (389). A good follow-up session. Monday the 7th brings a bit of rain, but the morning is glassy again with a 3 ft S swell. It's a little different direction, but could be worth a look.
Now, moving into the second week, the long-range stuff shows potential. Tuesday the 8th of September afternoon sees a jump in size to 10 ft from the S, with a period of 14 seconds. That's a lot of energy (3367) and it's borderline for experts only. The wind is light onshore, so it could be a bit lumpy, but for the crew charging, it's a massive window. The following morning, Wednesday the 9th, is glassy again with a 5 ft S swell, and the forecast is calling for very good surf. That's another strong contender.
Later in the week, Friday the 11th is marginal, but then Saturday the 12th of September morning throws a curveball. A 6 ft NW swell, short period of 8 seconds, glassy conditions. The energy is solid (868). That short period, glassy wind, and a clean reef like the Slot could produce some fun, punchy waves, especially for the more experienced. The wind stays light onshore for the rest of that weekend.
So, to sum it up: the first few days are a write-off, but from the 3rd of September onwards, we start seeing windows. The absolute best bet is the morning of Saturday the 5th of September, with the glassy 3 ft SSW groundswell. For the bigger, more powerful stuff, the morning of Tuesday the 9th of September is another standout, and the short-period NW swell on the 12th is a wildcard worth watching.
