Big Bay Surf Forecast and Surf Report

Alright, crew, Rusty here. Let’s break down the waves for Big Bay. This spot is exposed to the open ocean, really loves a good SW groundswell, and the water is way colder than it should be for this time of year—checking in at 56°F with a 4°F anomaly.

We get the first proper surf on Saturday, August 1st. A clean 4ft SW swell, 14-second period, with a light cross-off breeze from the ENE. The wave energy is moderate (585), and the morning looks very good. A nice way to start the weekend.

Sunday the 2nd is a bit average with messy cross and cross-on winds. Better to sit this one out.

Monday, August 3rd is the first real standout. The morning is glassy, a 5ft SW swell, 12-second period, and a NNE breeze that’s turned it to glass. The combined energy is moderate (795). This is clean, fun-sized surf—perfect for an intermediate surfer, and no crowds are mentioned.

The swell builds through the week, but Wednesday, August 5th is a mess with 15 mph cross-on winds and a 7ft choppy, blown-out wave. Don’t bother.

Thursday, August 6th is where the big boys come out to play. A powerful 13ft WSW swell, 13-second period, and the energy is ripping at 5723. The wind is a clean cross-off from the SSE. This is expert-only territory—way too big for beginners, and even experienced surfers need to be on their toes. This is the best wave of the entire forecast.

Friday the 7th and Saturday the 8th stay big, but the wind gets messy with onshore and cross-shore chop. The size is there, but the quality is average.

Sunday, August 9th through Tuesday, August 11th is a massive swell event. The combined energy hits five digits—12945 on Sunday morning with a 20ft SW swell. The wind is clean, but the forecast says it’s simply too big for this break. Even experts will be looking at a close-out. By Tuesday afternoon, the swell drops to a more manageable 8ft, and the energy is still strong (3434), with a clean cross-off breeze. That afternoon window is a good one for the experienced.

We get a beautiful long-period groundswell on Wednesday, August 12th and Thursday, August 13th with a 7ft WSW swell and an 18-second period. The combined energy is moderate to strong (3162). The offshore wind from the SE on Wednesday morning will make for clean, lined-up waves, but that very long period can make things a bit straight at a beach break. Still, a great option.

The final week, from Friday, August 14th onward, fades into smaller, cleaner surf. The morning of the 15th offers a 7ft WSW swell with a clean cross-off breeze and moderate energy (1800)—a decent Saturday for the experienced.

Sunday, August 16th is back to being too big, with a 15ft swell and very high energy.

Bottom line: Thursday the 6th is the call for the experts, and Monday the 3rd morning is the best for everyone else wanting clean, glassy surf. The big swell window from the 9th to the 11th is mostly for watching, but Tuesday afternoon could be a sneaky good one.

Stay sharp, and don't be late for the 3rd. The 6th is for the brave.

Rusty.
