Big Bay Surf Forecast and Surf Report

Alright, this is Rusty, and I’ve got the goods on Big Bay. We’ve got a solid run of surf coming through, but it’s a bit of a mixed bag at first. Let’s get into it.

Right off the bat, the water temp here is about where you’d expect for this time of year, so no need to dig out the thickest wetsuit just yet.

The weekend kicks off on Saturday, August 29th, with a clean 5ft swell from the WSW, period a solid 14 seconds. That’s a proper groundswell. The morning is your window with a light offshore breeze, making for clean conditions. The wave energy is strong, around 828, so it’s got some push. The afternoon sees the wind swing onshore and chop it up, so get it early.

Sunday, August 30th, the swell jumps up to 8ft from the SW. This is getting into expert territory – too big for beginners. The wind is cross-offshore, keeping it clean, but the power is serious (energy at 2051). This is a big, powerful ocean.

Monday, August 31st, the swell drops back to a more manageable 6ft from the SW. The morning is clean with a light offshore breeze, and the energy is still moderate (961). That’s a good day for an intermediate surfer.

But the real standout window starts mid-week. Wednesday, September 2nd, is the first absolute gem. The morning is pumping 10ft of SW swell at 13 seconds, with a light offshore wind. The wave energy is massive (3527), and the conditions are described as excellent for experienced surfers. This is a big, clean, powerful day.

The next big highlight is way out there on Saturday, September 12th. This is the crown jewel of the whole forecast. The morning sees an 12ft swell from the SW with a 14-second period, and a gentle offshore wind. The wave energy is through the roof at 4314. The afternoon is nearly as good with 10ft and the same clean offshore wind. Both sessions are rated as excellent for experienced surfers. This is a day for the crew who know what they’re doing and can handle serious size. Mark your calendar.

Between those big days, there’s a pulse of SSW swell around the 4th and 5th of September, but it’s short period (8 seconds) and looks a bit junky. The waves are there, but the quality is not the same. After that, the swell fades into the 2ft to 4ft range from the 7th to the 9th, with clean conditions but small and weak energy. Kite surfers might get more out of those days.

Sunday, September 6th, is a weird one. The morning is a write-off with onshore wind and rain, but the afternoon turns glassy with a 4ft, 15-second groundswell. That’s a sneaky good session if you’re patient.

The end of the second week, from the 10th onwards, looks promising again. Thursday the 10th brings a 6ft, 17-second swell from the WSW, but the wind is messy. Then Friday the 11th has a 10ft, 15-second WSW swell with clean offshore wind, but the energy is a staggering 4692. That’s serious power. It’s a solid day, but the 12th is the best of the best.

For the average surfer, aim for the August 31st to September 1st window, or the glassy session on the 6th. For the experts, September 2nd and especially September 12th are the ones to chase. The crowds at Big Bay can be an issue, so get in early for the standout days.
