Jacobs Bay Surf Forecast and Surf Report

Hey everyone, Rusty checking in from Jacobs Bay. This is a mellow beginner-friendly spot that's fairly consistent, open to the SW swell and likes it best from the WSW. The water's at 53°F – that's a massive 7°F colder than normal for this time of year, so it's really unusual. You'll be needing a thick suit and booties for sure.

We've got a bit of a mixed picture over the next two weeks, but there are a couple of sessions that are absolute standouts. It kicks off this Sunday, September 6th, with some proper groundswell. Sunday morning looks clean with an ESE cross-off breeze at 9 mph and a solid 7ft SW swell running with a super long period of 18 seconds. The energy is massive (3251). This is serious, powerful stuff – way too big for beginners and really for experienced surfers only. That long period means the waves will be well-shaped but there'll be long waits between sets. The afternoon gets choppy, so hit it early.

Monday, September 7th is another beauty. Glassy conditions on Monday morning with that same 7ft SW swell, but the period drops to 14 seconds. The energy is still strong at 1527 and it'll be clean. Again, it's a big wave for learners.

Tuesday morning, September 8th is glassy too, but the swell drops to 4ft from the SSW with a period of 12 seconds. This is a much better size for the beginners that Jacobs Bay is famous for, and it will be clean with barely any wind. The energy is moderate (597).

Things go a bit quiet and messy after that. Wednesday and Thursday see some huge swells (over 10ft) but with strong or onshore winds, making things either too big or choppy. Friday the 11th has a clean morning with a 7ft SW swell (2531 energy), but it's still hefty.

The big standout, the one to plan for, is Sunday morning, September 6th. That combo of a huge, long-period SW groundswell with clean cross-offshore wind is about as perfect as it gets here, but you need to be an expert to handle it. The waves will have serious grunt. It might get a little busy as crowds can show up sometimes, but for a session this good, it's worth it.

We get another pulse of big, clean swell coming in from Thursday, September 17th through Friday, September 18th. Thursday morning the 17th has a massive 13ft WSW swell (4980 energy!) with a strong SSE cross-off breeze. Experts only. It's clean, but the size is absolutely pumping. Friday morning the 18th is more manageable with a 6ft SW swell (1650 energy) and a light offshore E breeze at 9 mph. That's a great window for the stronger intermediate crowd. The period is 12 seconds.

After that, the swell drops and the wind gets messy. So your best bets are definitely in the first week and that second pulse in week two. Lock in Sunday, September 6th morning – it's the best of the lot if you're up for it.

Rusty.
