Malua Bay Surf Forecast and Surf Report

Alright, Rusty here again, same story, different numbers. Let's talk in feet and miles per hour.

The first few days are mostly a dog, but there are a couple of days worth marking on the calendar. The real standout for glassy, powerful waves is sitting at the very end of the run, so don't get too itchy.

First up, Thursday, September 10th. Malua Bay is getting a solid 7ft south swell, with a period of 9 seconds. Water temp is 63°F, which is about average for the time of year. That's a decent amount of juice, with a combined energy reading of 1076 (moderate to strong). The wind is a light cross-offshore breeze out of the south at 9 mph, which is going to keep things clean. This is for experienced surfers only; there's some heft in it. By Thursday afternoon, it pushes up to 7ft from the SE, but the wind swings cross-shore, and the energy jumps to 1239, so it’ll be a bit more chopped up.

Then we hit a dead zone. From Friday, September 11th through Wednesday, September 16th, it’s a real struggle. The swell tanks, the wind is mostly onshore or junk, and the scores are flat. You’re looking at tiny, weak waves for the best part of a week. A few mornings show a little puff of cross-off breeze, but with swell under 3ft, it’s a hard pass.

Now, look ahead to Saturday, September 19th. This is the one to circle. By Saturday morning, we’re looking at 7ft of SSE groundswell with a long 12-second period. The combined energy is a serious 1321 (strong). The catch is the wind is onshore from the NE at 6 mph, which is messy. The period is long enough that it might be a bit too lined up for the beach, but there will be some serious power. The crowd factor at Malua Bay says "often," so you might have to share. It’s a standout for size and power, but the wind is the key.

Sunday, September 20th morning looks a bit more user-friendly. The swell has dropped to a punchy 5ft from the SSE (10 seconds), energy is still a solid 495, but the wind is a clean 9 mph cross-off from the SSE. That’s a far cleaner look. It’s an excellent morning for someone who can handle a bit of power.

Finally, Friday, September 25th. This is the big one, but there is a serious warning. The model is showing a massive 12ft to 13ft south swell rolling in with a 10-second period, and a combined energy reading of over 2800 (very strong). The wind is a perfect cross-off from the south and SSE. The forecast even says wind and tide are favorable, but at this size, Malua Bay is simply too big for the break. It’s a bomb, but only for the absolute core crew, and honestly, for the rest of us, it’s a spectator sport.

So, to wrap it up: the best bet for a clean, solid session is Sunday, September 20th morning at Malua Bay. The standout for sheer power, if you’re an expert, is that early window on Saturday, September 19th, but the wind needs to cooperate. The end of the run on the 25th is for the camera, not the board.
