Ninja's Surf Forecast and Surf Report

Alright, this is Rusty, and I’ve got the goods on Ninja's.

We’re starting off a bit slow, but the first real surf comes through Saturday morning, September 5th. You’re looking at a clean 5ft swell out of the SSE with a 10-second interval, and the wind is off from the NNW at just 3 mph. That’s glassy, clean conditions. The combined wave energy is a solid moderate 392. This reef break is fairly consistent and loves a south swell, so it’s lining up real nice. For beginners, it’s a good size—under 5ft—and the conditions are sweet.

Saturday afternoon gets even cleaner. The swell drops a touch to 4ft, but the wind goes glassy—WNW at 3 mph. That’s about as good as it gets for clean faces. Energy is still moderate at 323.

Sunday the 6th is a mixed bag. Morning brings a light cross-shore from the SW at 6 mph, which puts a bit of ripple on the surface, but the swell holds at 4ft and 10 seconds. The afternoon cleans up with a cross-off wind from the WSW, making it rideable again. But nothing beats Saturday.

Monday the 7th is tricky. We’ve got a risk of thunderstorms and a cross-shore wind, with the swell dropping to around 3ft. It’s marginal, so pick your tides carefully.

Then Tuesday the 8th throws us a curveball. Morning brings a clean 4ft swell from the SE, 9-second period, with a light cross-off breeze from the west. Energy is moderate at 404. The afternoon though—just 2ft from the SW with a 15-second period. That’s a long-period groundswell, and at a reef like Ninja's, that often means super clean, lined-up waves, even if it’s small. The wind is still light and cross-off. Quality over quantity.

Wednesday the 9th gets a little bigger in energy but smaller in height. We’ve got 2ft to 2ft swells, but the period jumps to 18 seconds in the morning and 17 in the afternoon. That’s very long-period energy. Combined energy reads 554 and 611—solid moderate. Wind is cross-off from the WNW at 9-12 mph, keeping it clean. This is more of a mellow, long-period groundswell setup.

Now, here’s where it gets real. Thursday the 10th, we start seeing a jump. Morning brings 5ft from the SSW at 16 seconds, and energy jumps to 1520—that’s strong. By the afternoon, it’s 5ft, 16 seconds, and energy at 1602. Wind is cross-off at 12 mph. This is expert territory. The size is getting up there, and the power is serious.

Friday the 11th keeps the energy high. 4ft in the morning with a 20-second period—very long period—and energy at 2099. Afternoon goes to 4ft from the S, but the period is still 20 seconds, and energy hits 2463. That’s very strong energy. This is a serious groundswell. For a reef, this could be epic, but it’ll be big, powerful, and for experienced surfers only.

Saturday the 12th sees the biggest peak: 7ft from the SSW at 17 seconds in the morning, and 6ft in the afternoon. Energy is north of 2000 both sessions. Wind is cross-off from the west at 12-15 mph. This is the standout window if you’re an advanced charger. Crowds are likely at Ninja's, but for a wave this good, it’s worth it.

After that, it slowly drops through the second week. Sunday the 13th still has 5ft at 15 seconds, energy around 900, but the wind picks up to 15 mph. It stays rideable but not as clean. Through to mid-week, we’re seeing 3ft to 4ft swells with periods around 14-15 seconds, and energy dropping into the 600-900 range.

One notable late entry: Wednesday the 16th of September. Morning shows 3ft from the SSW at 18 seconds, cross-off wind at 9 mph, and a “very good surf conditions” tag. Energy is 978. That’s a long-period groundswell with clean conditions, and it’s a promising little pulse for the second week.

The last few days—17th to 20th—are smaller and more marginal. Swells hang around 2ft to 5ft, but the period drops to 11-15 seconds, and winds stay cross-off. Nothing to get too excited about, but still rideable for a quiet session.

Overall, the standout is Saturday the 12th of September—7ft, SSW, long period, and cross-off wind. Big, powerful, expert only. For the average surfer, Saturday the 5th is your best bet with glassy conditions and clean 5ft waves.

This is Rusty, signing off.
