Barometer readings

[nmgar]

I've read many times that rising/high barometric pressure is best for fishing but I don't understand why.

Air pressure at sea level varies around 1 atmosphere; at 10 metres underwater the pressure has increased to 2 atmospheres.

Any change in atmospheric pressure due to high or low pressure systems, say from 950 to 1020 kPa can only be a change of about 0.1 atmosphere.

That's the same change experienced by the fish if they move from 10 metres deep to 11 metres deep, where I wouldn't expect the fish to come on or off the bite.

What am I missing?

Purple I tend to fish when time allows and the weather is suitable but still keep an eye on the barometer.

Low pressure and High pressure systems that you see Jane Bunn talk about on the news relate to the barometer.

A low pressure system is associated with poor weather and the barometric pressure drops a high is typically good weather and has a higher barometer. Rising Barometers from a low to a high and a change in pressure prior to a low can be the best time to go fishing.

Does jane bunn talk ??

Ive caught most off my big snapper on a dropping barometer ...how much that counts ive got no idea

But I do know any chance I get I will go for a fish....rising or falling.

have access to nude up secret spot book sure helps.

hey steve, while you're downloading, also put in http://www.fishingreminder.com link, put in your location & it'll have some bonus info for your planning :cheers:

generally I find the rising barometer, rising tide and a bit of wind all present the ideal conditions. When the barometer is over 1020, generally its fish on.

I find like others rising or high barometer means better fishing. I feel it effects fresh water species more so than salt. Having said that mainly bass as that's mostly all my fresh water fishing. Low or fast dropping barometer may aswell forget about it. Over 1000 and the fish will bite. Salt water fishing if I have a window where I can go. I'll go regardless of barometer and hope for the best.

barometer reflects the general weather pattern. If it drops a lot most fish will go spastic for a few hours before going off the bite as bad weather sets in. All depends on how game you are to ride the incoming change out. Rising barometer generally brings better stable weather. Everything else becomes more active resulting it predators doing the same. Steady high or low barometer doesn't really produce exceptional fishing, a few fish, but not the numbers in my experiences

thanks guys, appreciate the input.
cobby hahaha yeah im not game enough to be a sitting duck in PPB when the weather turns.

Cheers....this free website you linked is better than the 'fishing calendar' app I downloaded for $10 recently (it does the same thing, but has a lot more features)

I don't know how they sense it but I have read a couple of scientific studies that found that the behaviour of farmed trout changes depending on the weather. Whether the barometer affects all fish equally I don't know but it is certainly plausible and is backed up by a lot of annecdotal evidence from fishermen

Another +1 for Fish Ranger.
Also I go whenever the time and conditions permit.
Good info from many about barometer effects.

I'm not disputing that it happens, 4litres, It's just the physics of it that doesn't make sense to me.
