Climate is what you expect. Weather is what you get.
Weather is the condition of the atmosphere over a brief period of time.
For example, we speak of today's weather or the weather this week. People in Minneapolis-St. Paul expect a white Christmas, and people in New Orleans expect very warm, humid summers. It is no coincidence that we pack differently when we travel in March to Orlando, Florida or to Vail, Colorado. These examples begin to show how we use climate to live our lives.
