Jacobs Bay Surf Forecast and Surf Report

G’day, Rusty here, and I’ve been staring at the charts for a while. There’s a pretty solid run of surf coming up for Jacobs Bay, but you’ve got to be patient and pick your windows. The first week has some real gems, but there’s a big stretch of nothing at the end where you’ll want to find something else to do.

Things kick off Monday morning, the 20th of July. The bay is glassy, dead calm, with a 6ft SW swell rolling in at 9 seconds. The energy is moderate (678), and it’s a beginner-friendly spot. The water temp is about average for this time of year, nothing unusual. It’s a great little session to start the week.

The real standout is Tuesday morning, the 21st of July. The swell picks up to 7ft from the SSW, and the period stretches out to a beautiful 14 seconds – that’s groundswell with proper energy (1705). The wind is cross-offshore, and the report says it’s clean. This is the best of the first week. The crowd might be around sometimes, but when it’s this good, you don’t care.

Now, Friday morning, the 24th of July, is a different story. The swell is 12ft from the SW at 14 seconds – that’s a lot of water moving (4899 energy). The wind and tide are favorable, but this is too big for beginners. It’s expert territory only. The afternoon stays big at 10ft, but the wind gets cross-shore and messy.

The next week has some good, clean mornings. Saturday the 25th, Sunday the 26th, and Tuesday the 28th all have clean, cross-offshore winds and solid 6ft to 7ft SW swell. The energy is good (2245, 1073, 1378). Nice, consistent waves for experienced surfers.

Then comes a big gap. From Wednesday the 29th, the surf gets a bit tricky, and from Friday the 31st of July all the way through to Sunday the 3rd of August, the conditions go bad. The winds get strong, the swell drops, and it’s blown out. Poor surf, not worth paddling out.

But hold on. Monday the 3rd of August, the charts show a massive pulse. The swell hits 12ft from the WSW, with a 15-second period (5928 energy). The wind is offshore and light. Again, this is an expert-only wave. Too big for the average punter. The same goes for Tuesday the 4th – 16ft of W swell at 14 seconds (8544 energy). That’s a beast. If you’re a pro, look out.

So, the pick of the entire run? Tuesday morning, the 21st of July. That’s your standout. Clean, long-period groundswell, and the bay will be working. The other big swells are just too much for this spot.

Rusty.
