Ninja's Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about the next stretch at Ninja's. It's a reef setup, and it’s pretty consistent in picking up swell, but we’ve got a bit of a mixed bag coming our way. The water’s sitting around 87°, which is a touch warmer than normal for early September, so you'll be comfortable even if the waves aren't firing just yet.

The week starts off with a pulse of solid, long-period groundswell rolling in from the SSW, but the wind is the problem. Friday morning we’re looking at a 1.3m (4 ft) SSW swell with a thumping 19-second period, and the energy is wild – 2080 (strong). But that cross-off wind from the WNW at 30 km/h (19 mph) is gonna put a bit of a texture on it. It’s surfable, but not glassy. That same pulse runs through Saturday and Sunday, with heights around 1.4m (5 ft), still with that long period (15-17 seconds) and still cross-off wind. The combined energy is strong to very strong, but the wind just won't give us that perfect clean face. There’s a bit of a drop-off on Monday morning (0.9m / 3 ft), but the afternoon bumps back up to 1.3m (4 ft) with a 17-second period – that’s the best quality of the early week for me. The wind eases slightly to 20 km/h (12 mph), so it’s still cross-off, but a bit more manageable.

Tuesday and Wednesday are smaller, in the 0.9m to 1.2m (3 to 4 ft) range, with energy dropping into the moderate zone. The swell direction stays SSW and the period hangs in, but the wind stays up. Nothing to call in sick for.

Things get a bit choppy from Thursday the 18th through the weekend. The swell starts to mix up with some shorter-period stuff, and the wind swings more cross-shore, which will make for a lumpy surface. The combined energy takes a big dip into the low hundreds and even drops to zero on some days – that’s weak and not worth paddling out for. The swell does bump up to 1.5m (5 ft) and then 2.0m (7 ft) on the 19th and 20th, with the 2.0m (7 ft) on the afternoon of the 19th coming with cleaner cross-off wind. That 2.0m (7 ft) SSW swell with 15-second period and 2320 energy is the standout from that stretch, but the wind is still a moderate breeze so it’s not perfect. Anything over 1.5m (5 ft) here, especially with this reef, is getting into expert-only territory, so the beginners should sit that one out.

After the 20th, it’s a rough run. The wind stays up over 30 km/h (19 mph) for days, the swell gets short and weak, and everything gets scored as poor. There’s a blip on the 23rd afternoon with a 1.7m (6 ft) swell from the west, but it’s only 7 seconds – that’s a short-period, wind-driven lump, not a proper wave.

Further out, around the 24th and 25th, we get some very long-period swells again (up to 21 seconds), but the heights are tiny – 0.5m to 0.9m (2 to 3 ft). That kind of period on a reef like Ninja's *can* produce some beautiful, long lines, but with such little height and the wind still cross or onshore, it’s a gamble.

Honestly, the best bet in this whole 16-day window is the early part: the afternoon of Monday the 14th and the afternoon of Saturday the 19th. The 14th gives you a manageable 1.3m (4 ft) with decent period and lighter wind, and the 19th gives you the biggest clean swell, but it’s for experts only. There are long gaps of several days where it’s just not worth it, so pick your window and don’t force it.

Stay tuned, forecasts can change. This is Rusty, signing off.
