Thread: Barometric pressure

Most believe high pressure wrecks fishing while low can trigger it. Well it's extemely high now and fishing is slow. I see rain is in the forecast for Wednesday which should mean lower pressure. My fish graph if you believe in them shows poor today, average Tuesday, Good Wednesday, Good Thursday, excellent on Friday!, good on Saturday ,and average on Sunday.

I think that when the BP does the most damage to fishing is when it is unstable. It affects their air bladder in a way that is uncomfortable for them and they shut down. Even an extremely high BP can be productive if it is steady, you just have to look deep where their bladders aren't as effected by the high pressure. Not saying that the fish aren't in those shallower waters, but good luck getting them to bite. The oppisite is usually true for low pressure systems, especially right before a storm/front. I have caught them just inches below the surface in the dead of winter right before a front. This is just my opinion by the way, but it has been a very effective way of getting me on the fish more quickly and cuts out a lot of guess work.

I always seem to to do just before a storm front as baromentric pressure drops. Behind a front with bluebird skies and high pressure is the worst. Sometimes after 3 days post front fish fire back up, guess they get adjusted.

I think that is because the pressure falls and evens out just before a front. Then it starts climbing again after the front and is unstable for a couple of days. If you have a graph that predicts BP, look for those steep climbs and falls followed by an evening out period. My best fishing comes when that "lull" happens in the 29.80-30.15 range. Ever notice that the fish suddenly turn on for a few minutes, then turn off like a light switch? I would bet that your graph will show a rise or fall in BP with a period of stability during that time. Again, JMO but I have found this to be true 90% of the time. But hey, i'm still learnin!

I wonder if BP affects humans. I need something to tell Mrs DP when I don't want to work on the house.

Here is a link to a good weather map tha will show Highs and Lows plus fronts and wind. I use it on the farm to see where weather fronts are.

There is a big low heading our way. But if we heavy rain it will mess things up .
