“GO / No-Go” tide charts for halibut and salmon

What’s up, guys?

I had a few minutes to spare while listening in on a (mandatory but not at all relevant to me) work meeting, so I pulled together a couple tide charts in Excel, ran a couple simple calcs, and applied some conditional formatting.

The first tab gives “GO / No-Go” recommendations for SF Bay halibut fishing based on the magnitude of tide swings predicted for the Alameda Rockwall Area. Right now it’s set to give a “No-Go” call for a certain timeframe if the tide swing is over 4 ft (either outgoing or incoming). As we know, big swings equal big currents and murky water, neither of which are ideal for halibut fishing.

The second tab lists Bolinas tides. Aside from just listing high and low tides (helpful because salmon fishing tends to heat up around tide swings) it also gives a “GO / No-Go” for the Brighton launch based on the magnitude of the high tides. It’s current set to say “GO!” if the high tides are less than 4 ft magnitude - above that the Brighton launch/landing can be sketchy. (This only matters if a high tides lands at launch/landing time, and the the channel certainly might be an option on some “No-Go” days.)

Happy to email the Excel files to anyone who’s interested. Just shoot me a PM with your email address.

Now we just have to hope this COVID-19 wave will subside enough for Marin County beaches to open up....

Cheers,

dude, awesome.  you just helped me tremendously with putting in my time off at work.  perfect, will send you a DM.  Thanks!

No prob! If this helps a few people catch fish it'll be 10 minutes well spent!

Very cool! might see if i can put it in a powerBI model and do some data visualization haha

Haha! Go nuts!

If you want more raw data, you can find it by clicking the "Click Here for Annual Published Tide Tables" on the NOAA tide page. (See example below)

wow...good rule of thumb.
we did get a 32" halibut and a few other we released on Monday 25th, that was a big ass minus tide something like 7+ foot swing in the AM and a nearly 6 foot swing PM.

all i am saying is that depending on the tides you have to pick your spots and your timing

  That's good stuff.   But you got me thinking: I was born, and my working life was too soon -where was "working" from home and virtual meetings when I was trapped in endless meetings that had little to do with me and that seemed to run the whole damned lunch hour even if it all could have been said in 5 minutes?

Of course. Lots of halibut are caught in less than perfect conditions, but “ideal” days have smaller tide swings that let the water clear up a bit.

Haha! We still have plenty of those meetings during “normal” times when we’re working in the office...
