There is a rhythm, then, in the weather, or at least a sort of rhyme, a repetitive sequence.  All those folk rules that attribute weather changes to the phases of the moon, or to some other simple periodicity are not so far from the mark after all. 

–Wolfgang Langewiesche, What Makes The Weather, 1943

Our greatest mistake is to view the universe on our own terms.  The Earth has existed for so many millennia, but it is difficult to imagine time outside the brief life of a human being.  We view natural changes in climate as dramatic and fatal, when in the larger scheme of things, they are just a small anomaly in the extended history of cataclysmic change. 

Experienced gardeners tend to take the variations in weather in stride, for over the years they accumulate a body of knowledge that predicts how plants will react to these annual changes.  While young in garden terms, we must all learn to become keen observers of weather and how the earth and its botanical inhabitants respond.  Thus we too shall earn the wisdom to understand this often unpredictable heavenly behavior.
