Jacobs Bay Surf Forecast and Surf Report

Alright, let’s talk Jacobs Bay in feet and degrees, the way we used to before all them fancy meters.

The first real look we get is Friday, July 31st. You’ll want the morning session. It’s a clean 4ft of SW groundswell, 12-second period, with a light east-southeast offshore breeze. The water temp is 57°, which is a bit colder than usual for this time of year. Swell energy is moderate at 446. It’s a gentle start, but for a beginner-friendly, fairly consistent spot that can get a crowd sometimes, it’s a nice way to shake off the rust.

Now Saturday, August 1st morning – this is a standout. The swell holds at about 5ft from the SW, but the period stretches to a juicy 14 seconds. Proper groundswell, plenty of energy. The wind is a light east-northeast offshore, keeping the surface glassy clean. Combined energy goes up to 731. For a break like this, that long period SW swell can line up real pretty. This is the one to circle.

But the crown jewel of the first week is Monday morning, August 3rd. It’s dead glassy. No wind at all. You’ve got a clean 4ft SW swell with a 12-second period, and the combined energy hits 935 – getting into that strong range. The surface will be like a mirror. If you can only surf one morning in the first week, this is it.

Then we hit a rough patch. From Wednesday, August 5th, the swell goes nuts – we’re talking 10ft to 14ft of SW swell with energy readings in the thousands. That’s expert-only territory at a break that’s not suited for it. The winds are mostly cross-shore or onshore. Keep your board in the car for a few days.

The wind goes full gale from August 10th, so those days are a write-off.

The second week brings some redemption. Wednesday morning, August 12th, goes glassy again with a 5ft WSW swell, 13-second period. Clean as a whistle.

Then Thursday morning, August 13th, is the second-week standout. A light south-southeast cross-offshore wind, a 4ft WSW swell but with a 14-second period. That long period gives it real punch for its size. The combined energy is 838 – strong. For a fairly consistent break, mornings like that in mid-August are a gift. Friday morning, August 14th, is also clean with a 5ft swell and light winds.

The very end, Saturday August 15th, the wind swings north and kills it. Small, mixed-up, cross-shore junk.

So, the call: Saturday August 1st and Monday August 3rd are your best shots in week one. For week two, get on Thursday August 13th morning. Watch the tide for that long period swell.

Rusty.
