Weather refers to the day-to-day atmospheric conditions at a specific place and time, varying frequently (e.g., today it's sunny, tomorrow it might rain). It describes short-term phenomena like temperature, humidity, wind, and precipitation for a few hours or days. Climate, on the other hand, is the average weather pattern observed over a long period, typically 30 years or more, for a large region. It represents the general atmospheric conditions of a place (e.g., India has a monsoon climate). Climate is relatively stable and predictable over decades, while weather is highly variable and can change rapidly.
