Cones are open when dry and closed when wet. This assures that the small, wind disseminated seeds will be dispersed during relatively dry weather, and thus, the distance traveled from the parent tree will be enhanced. (Wikipedia)

∙ 14y agoFact: "One of the most reliable of all natural weather indicators are pine cones. These have traditionally been used to forecast the weather as they change shape according to whether it is wet or dry. In dry weather, pine cones open out as the scales shrivel up and stand out stiffly. When it is damp, they absorb moisture and as the scales become flexible again, the cone returns to its normal shape." We keep one on a window sill as a barometer.
