Best Times for Fishing

One hour before and one hour after high tides, and one hour before and one hour after low tides. Inland, the times for high tides correspond with the times when the Moon is due south. Low tides are halfway between high tides.
During the "morning rise" (after sunup for a spell) and the "evening rise" (just before sundown and the hour or so after).
When the barometer is steady or on the rise. (But even during stormy periods, the fish aren't going to give up feeding. The smart fisherman will find just the right bait.)
When there is a hatch of flies—caddis flies or mayflies, commonly. (The fisherman will have to match his fly with the hatching flies or go fishless.)
When the breeze is from a westerly quarter rather than from the north or east.
When the water is still or rippled, rather than during a wind.
When the sun and moon are correctly positioned, see: "the solunar theory".

The Solunar Theory

The solunar theory was initially proposed by the American John Alden Knight in 1926 and has been supported by the systematic analyses of scientists and biologists in subsequent years. It is based on experimental incidents from which it can be deduced that the action of the sun and the moon influences the activity of all living beings in nature. The times of day in which living beings show greater activity are the so-called solunar periods.

We can distinguish two types of solunar periods:

Major periods: have approximately 2 hours duration although on certain occasions they may exceed 3 hours. They begin the moment of the lunar transit (when the moon is overhead) and the opposing lunar transit (when the moon is under our feet). Normally these are the moments of greatest fish activity during each day. The most fervent supporters of this theory state that there is not one species of sport fish that cannot be found eating during a major Solunar Period.

Minor periods: are intermediate periods of lesser duration (approximately 1 hour) which coincide with the rising and the setting of the moon. During these periods there is also an increase in fish activity in relation to the rest of the day.

The solunar periods appear 4 times every lunar day. Remember that a lunar day lasts 24 hours and 50 minutes approximately so normally within the same day (24h) we will find 2 Major Periods and two Minor Periods. ;

Increase in activity

We can also observe a notable increase in the activity of fish if the sunrise or sunset takes place during the solunar period.
