Big Bay Surf Forecast and Surf Report

Alright, friends, Rusty here. Let’s cut through the noise and get straight to it. We’ve got a solid run of southwest swell on the charts for the next couple of weeks. It’s got some serious pop to it, so it’s not for the timid, but there’s definitely some good ones in there if you’re keen.

The first couple of days are a bit of a tease. Monday has some small, crossed-up energy, but the tide is making it a pain. Tuesday is glassy and clean though, with a nice 5ft SW swell rolling in. It’s a sign of things to come, but still a bit small.

Then things get serious. Wednesday the swell jumps to around 7-8ft, but the wind goes cross-on and chops it all up. It’s going to be a messy, bumpy day. Better to wait it out.

Thursday is where it all connects. That southwest groundswell builds to a proper 10ft, and with light cross-offshore winds, the surface is going to be clean. The combined wave energy is strong, hitting 3136 on the morning push. This is excellent surf for experienced surfers. It’s big, with a 13-second period, so there’s real power. If you’re an advanced surfer, this is the first standout.

Friday keeps the size up, pushing 12ft in the afternoon. The wind stays offshore, the surface is clean, and the energy soars to 4250. Another big, strong day for experts only. The southwest direction is perfect for Big Bay’s exposed setup.

Saturday morning drops slightly to around 8ft, but it’s glassy and clean. This is a great window for strong intermediates and up, with excellent conditions and a bit more manageable size. The energy is still moderate. Saturday afternoon gets a bit lumpy with a cross-on breeze though.

Sunday morning is another clean one at 8ft, but the afternoon is a different story. The wind howls from the SSE at 28 mph, and the swell jumps to a massive 15ft. The energy reading is off the charts at 6937, but it’s going to be a blown-out, chaotic mess. This is not a day for paddling.

Monday, the 10th, sees the wind even stronger, near gale force, with the swell still at 15ft. The energy is still enormous, but it’s wild. This is beyond expert level; it’s survival stuff. I’d give it a miss unless you’ve got a death wish. This setup looks far more interesting for the kite surfers than us paddle folk.

Tuesday, the 11th, the wind swings offshore and the swell drops to a very surfable 8ft. The surface is clean and the energy is still moderate. This is a great day for a lot of people, with conditions finally matching the size.

Now, looking into the second week, we’ve got another pulse of proper long-period groundswell. Wednesday morning, the 12th, brings in a 6ft swell with a 20-second period and glassy conditions. That period is exceptionally long, meaning powerful, well-shaped waves that will be best at a point or reef break, not a beach break that might close out. The energy is solid, and this is a promising standout, but remember, the long range is less certain.

Thursday and Friday keep the fun going with consistent 7-8ft SW swell and light winds. Friday morning looks particularly clean and glassy with that long period energy still in the water.

The weekend sees the swell easing a bit, but there’s still rideable 7-8ft surf. The wind could be a bit of a factor, but the following Tuesday, the 18th, looks like another big one, with the swell jumping back up to 13ft. That’s another huge, expert-only day on the horizon.

So, the two true standouts in this whole run are the Thursday and Friday, the 6th and 7th of August, with that big, clean, powerful southwest swell. And keep an eye on that Wednesday morning, the 12th, with the very long period and glassy conditions – that’s a special one if it holds up. Be smart, be patient, and pick your sessions.

That’s the long and short of it from Big Bay, where the water is sitting at about 57°, which is a bit colder than average for this time of year. Bring the booties.

Rusty out.
