The primary difference between weather and climate is the duration of time over which atmospheric conditions are measured.1

Weather refers to the state of the atmosphere at a specific location over a short period, such as throughout a single day or even hour-to-hour. It involves phenomena like temperature, humidity, precipitation, wind, and cloud cover.12
Climate describes the long-term synthesis of these atmospheric conditions for a given region, typically calculated over spans of 30 years or more. Rather than just an "average," climate includes the variability, extreme ranges, and frequency of atmospheric events.1234

To use an analogy, if weather is a single inning in a baseball game, climate represents the entire game. While weather is highly volatile and changes frequently, climate provides a more stable, long-term perspective on the atmospheric behavior of a specific area.1
