Barometric Pressure/astro Tables

[TennesseeBassmaster]

What is the optimal barometric pressure (please provide units) to be fishing bass or crappie? I realize the best time to fish is while pressure is falling, however, I would also like to know what barometric pressure is considered as High, Low, and Normal pressure.

Does anyone here follow the fishing astro tables? I find the data interesting but I don't know how relevant they are to fishing considering we face so many other variables as well. I'm particularly interested in what people think about these tables....I'm about to graduate with a degree in physics and I would like to connect some of the physics side of the affects the moon has on earth as well as what happens with fish during these times.

Thanks

In my opinion anything under 30 on the barometer. This can be argued.

This is an article I saved that I liked. also a link to a free refrence on fishing conditions based on moon phases and weather including pressure.

THE REAL SCOOP ON MOON PHASES

By Joe Bucher

Full Moon or Dark Moon? Major and minor solunar periods? Which is best? Does any of this moon mumbo jumbo make any real sense nor does it actually work? These are legitimate questions asked by thousands of anglers each year, and they deserve concrete answers backed up by some bonafide data. Yet as much as pro anglers endorse the effectiveness of moon charts and outdoor publications of every niche' continue to print them, rarely does either source validate these solunar claims with data.

It's not hard to find a solunar table of some kind. Nearly every fishing publication today publishes some kind of monthly solunar table, moon chart, activity calendar, action graph, or other similar version. All of these tables, charts, and calendars claim to predict daily feeding activity of fish with accordance to moon and solar influences. Yet, I, like so many other anglers, rarely find any consistent correlation with most of these references.

Finally, back in 1976, when I got into the fishing guide business full time, I really made it a point to compare my fishing catches to a number of solunar charts. Once I started logging my catches on a daily basis I developed a good data base. This finally put me in a position to compare hundreds of muskies, and thousands of bass and walleyes on a daily, monthly, and yearly basis to any printed solar/lunar reference. One of my key entries was the time of day. I figured a daily entry of fish activity would finally give me a mound of fishing data to compare with the various solar/lunar references on a given day to day basis. What followed convinced me that certain solar/lunar criteria simply had little or no daily influence.

Basically, I became so frustrated and disappointed with the lack of any real consistent correlation to most of the popular magazine charts today that I gave up on them completely. They simply did not work. I actually caught far more fish when they weren't supposed to bite. And when good fish and game activity did coincide, which was less than 10% of the time, it was plainly obvious that it actually had much more to do with the local weather changes than any predicted major or minor solunar period.

You would have thought that my accumulated research would have cured me from ever looking at a solunar chart again, but it did just the opposite. Why? Because I ended up discovering a certain solar/lunar influence that really did work. In fact, it worked so well that it was hard to believe at first. My daily fishing logs had surely disputed the commonly accepted correlations, but they just as surely pointed to indisputable evidence that a "certain" solar/lunar factor was really important.

Yes, I had flipped 180 degrees on the entire solar/lunar deal. I went from totally disbelieving to being totally convinced. In fact, I eventually got to the point where I myself began to predict the most probable daily, monthly and even yearly times when the biggest fish were most apt to bite. And what's even more incredible, was that I was right almost every single time! But perhaps what was even more unbelievable to me was that everyone else had missed this simple but really absolutely true key.

The real secret, I discovered, to solar/lunar influences on a daily basis was nothing more than knowing when the sun and moon rose and set on a 24 hour basis. That's right, it was simply a matter of knowing, to the minute, when the sun came up and went down, and when the moon came up and went down each and every day. My 21 year old fishing log revealed without question that fish were active during a 90 minute window surrounding each one of these four daily influences.

Now, I realize this sounds overly obvious, but I told you it would. Most of the solar/lunar charts, tables and graphs you see depicted in today's publications do not reveal nor coincide with these four vital factors. 1) sun rise, 2) sun set, 3) moon rise, and 4) moon set. Yet it doesn't take an astrologist to figure out how important the rise and set of the sun and moon has to be.

It's certainly no secret that feeding movements of both fish and game have been traditionally accepted as key during dawn and dusk -- this correlates with sun rise and sun set. Moon rise and set is a bit more tricky to key in on though since they can often occur at mid day or mid night. Overcast weather can also make it impossible to see a moon rise or set, and of course a dark/new moon is not visible to begin with.

The other "super secret" my logs revealed was the predictable frequency of big fish catches during the peak moon phases of full and new moon. Specifically, a lot more big muskies, walleyes, and bass were taken right on the scheduled calendar day of both the full or new (dark) moon peak, and continued for a three to five day stretch afterwards. In other words, if the full moon peak is on June 10th, June 10 thru 15 have great potential for trophies.

Backing up a bit, the four daily factors previously discussed (the rise and set of both the sun and moon) inside each one of these predictable monthly moon peaks (four days on the back side of the full or new moon) further nails it down. In other words, you want to plan your fishing trips to hit the peak of the full or new moon. Then you want to be on your favorite big fish spots during the daily rise and set of both the sun and the moon.

Finally, my logs revealed a third factor that really adds impact to this entire solunar secret. That unpredictable third influence is local weather. Whenever a local weather change coincides with the daily rise or set of either the sun or the moon, during a peak monthly moon period, big things happen in bunches. Big things meaning big fish. For example, give me a severe summer T-storm right at sunset, and just before moon rise during the new moon period and it's almost a sure bet that that I'm going to bag big muskies or the year's biggest catch of lunker walleyes. Or just as good -- put me on a steep rocky shoreline with some spawning ciscoes right at the start of a snow storm in the late fall just after sunrise and right before moon set during a full moon period. Big muskies, big pike, big walleyes and big lakers will be snappin'.

Could there be a fourth factor? Absolutely. In fact, there might even be a 5thor 6th. However, an easy-to-detect 4th factor of influence that adds even more impact to an already good situation is a change in the photoperiod, or laymen's terms -- a change in season. Photoperiodism is actually the measured ratio of daylight to darkness. The most drastic changes in the photoperiod occur in the spring and fall, but mini-differences are detected inside all seasons which are quickly detected thru their eyes and transmitted to their pituitary gland. The responses to these changes in the photoperiod trigger sexual responses such as reproduction and the development of eggs. This, in turn, also triggers increased movement and feeding binges by normally less active trophy fish.

I do realize how controversial my comments on solunar table validity may seem to some, but the facts speak for themselves. My data clearly points to sun rise, sun set, moon rise and moon set as The most important factors. The simple rise and set of both the sun and moon has far more impact than any other daily sun or moon position. That is, bar none, the single most important daily triggering factor of both fish and game.

Monthly peaks in both the full and new moon are a second factor definitely worth considering. When fish of all sizes are feeding infrequently due to a prolonged streak of bad local weather conditions, that small "window" of three to four days right after the actual moon peaks, full or new, may be the

only time that the largest fish of any species is truly cacheable. Fishing during the daily rise or set of the sun and moon during these key monthly moon phases is paramount.

Weather is also a legitimate third factor, and helps to elevate the impact of the daily rise and set of the sun or moon. It further elevates the entire realm of big fish possibilities when all three factors happen at relatively the same time. A changing weather pattern combined with a good monthly moon phase and rise or set of either sun or moon can activate some major movement from big fish.

If all of these things happen during a good photoperiod, look out! This is when the biggest fish of the year are generally caught. If your serious about taking such a fish, I'd suggest you start really paying attention to the real scoop on moon phases! Trust me -- thousands of entries in my fishing logs

can't be wrong. This stuff really works!

Barometric pressure, Stable

There have been numerous books, articles, charts, ect. published on this great mystery of bass fishing. A lot of the authors of these publications go through great lengths explaining how difficult it is to determine these times. It is really quiet simple to determine these times for your self with a little inside information. River and salt water publications go through great lengths explaining how difficult it is to determine tidal movements. The reality is that these best times and tidal movements are related to the moon's phases.

People in animal husbandry, farming, hunting, and fishing has used the moons phases for centuries. One of the oldest publications giving this information is the "Poor Richard's Almanac". The moon's phases are divided into four quarters, two of which are your minor times, and two of which are your major times.

The times for the major periods are as follows

An hour and a half prior the moon reaching its apex

An hour and a half prior to the moon reaching its perigee

The major periods are the first quarter new moon and the third quarter full moon.

The gravitational pull of the sun and moon is three times greater on the new moon than the full moon. At the time of the new moon the earth has the moon and the sun in a straight line pulling together. This first quarter, dark night phase differs from the third quarter full moon phase when the earth moves between the moon and the sun. The new moon dark night is only difficult on the angler because you must rely on your sense of feel when working your bait. If you want to really learn how to fish baits that require a lot of feel like worm or jigs try nights.

The times for the minor periods of these moon phases are as follows

An hour and a half prior to the raising of the moon on the horizon.

An hour and a half prior to the setting of the moon.

Now take into consideration the above listed times you end up with 3 hrs. of major time periods and 3 hrs. of minor times periods. This does not take into account weather, seasons, or your ability to locate fish!

I wish:

I could know the optimal barometric pressure ( in units ) for bass,

I could know the optimal temperature ( in degrees ) for bass

I could know the optimal wind velocity ( in knots ) for bass.

I could know the optimal clarity ( in inches ) for bass

I could know the optimal oxygen content ( in PPM ) for bass

I could know the optimap REDOX potential ( in mV ) for bass

I wish I could know the optimal conductiviy ( in microsiemens ) for bass

I wish I could know which were the optimal paramaters for fishing for bass and I wish I could be at the lake every single day measuring them before I decide if I fish or not.

You can´t do anything about them do you ? you can´t modify them, do you ? the only thing you can do is to select your baits and select the techniques that suit the conditions and play with the hand that Nature has given you. Fishing is an art form that depends greatly on the person practicing it, it´s like all the arts, the tools are the same for the guy painting your house than they are for Michael Angelo, Raphael, Picasso, so why the guy painting your house isn´t one of them ?

This subject could get as complicated as What Triggers the Spawn.

I wish I could give you a better answer, but all I know from expierence is I do better when the barometer has been steady for a while or when it is falling just before a storm. The full moon thing is spot on. About three days before and after. I don't know why but it seems the full moon has an effect on everything including people.

• High Pressure (30.50 +) = Clear Skies = Fishing Medium to Slow = Fish slowly in deeper water or near cover.
• Medium Pressure (29.70 – 30.40) = Fair Weather = Normal Fishing = Test lures, baits, and techniques to see what works.
• Low Pressure (29.60 -) = Cloudy/Rainy Weather = Fishing Slows = Fish slowly in deeper water or near cover.
• Rising Pressure = Improving Weather = Fish Slightly Active = Fish slowly in deeper water or near cover.
• Stable Pressure = Fair Weather = Normal Fishing = Best time to test lures, baits, and techniques to see what works.
• Falling Pressure = Degrading Weather = Best Fishing = The fish will attack anything you throw at them. (well, pretty much)

Standard Atmospheric Pressure is 2992 inches

This is an awesome post and will make us a better angler if we learn the lessons.

Two thousand, nine hundred and ninety-two inches of what?

Mercury!!!

I was trying to inject a bit of levity, but missed the mark.

I can't find my calculator, and can't do the math in my head. I need to stand in the shower to count to 21.

2992 inches Hg would be between 1400 and 1500 PSI. We'd all be smashed flat at that pressure. :D :D
