What term describes the average weather conditions for a region over a long period?

The term that describes the average weather conditions for a region over a long period is climate. Climate refers to the long-term patterns and averages of temperature, humidity, wind, and precipitation in a particular area, typically assessed over a minimum of 30 years. This concept contrasts with weather, which represents the short-term conditions of the atmosphere at a specific time and place. While humidity is a measure of the amount of moisture in the air, and a forecast is a prediction of weather conditions for the upcoming days, climate encompasses the broader, more stable patterns observed over an extended timeframe.
