Weather changeability details for Williamstown, New Jersey
Changeability is the amount that the weather changes
day-to-day. For temperatures, it's the difference (in number of degrees) between each day. Greater
day-to-day degree differences means more changeable weather. For precipitation, it's the percentage
of time that the next day is different than today &endash; i.e., a rainy day followed by a dray day
or a dry day followed by a rainy day. A higher percentage means that precipitation and dry days
alternate more frequently, thus the weather changes more.
