Weather is the short-term condition of the atmosphere. It includes temperature, rain, wind, clouds, humidity, storms, and pressure from hour to hour or day to day.
What climate means
Climate is the long-term pattern of weather in a place, usually measured over many years. A region's climate describes what conditions are typical, not what happens on one afternoon.
Why the difference matters
A cold day does not disprove a warming climate, and one hot day does not define a climate. Climate is the broader pattern behind many individual weather events.
Weather concepts like humidity, wind chill, heat index, and dew point help describe short-term conditions.
