Crickets chirping loudly indicate a pleasant day to follow. A clear, white moon tells you that the next day will be nice. Cumulonimbus clouds forming rapidly in the mountains on warm afternoons presage an intense lightening storm is on its way in minutes. Cobwebs on the grass are a sign of fair weather. Whether you are on the trail hiking somewhere, canoeing in the middle of the Okefenokee or, simply wondering whether you should head out to the lake on a fishing expedition, this knowledge can not only come in handy, it could potentially be a life saver.
Rhododendrons have the unique ability to act as temperature gauges.
As the air temperature rises, their leaves begin to unfurl. At 20 degrees they are completely closed and when the temperature reaches 60 degrees, they are completely open. The common Field Cricket can be another accurate thermometer. All you have to do is count the number of chirps in 15 seconds, add 37 and you have the temperature where he is sitting. The Snowy Tree Cricket and the Katydid can also be used with slightly different formulas.
