What is the difference between “weather” and “climate”?

“Weather is the day-to-day state of the atmosphere in a region and its short-term variations, whereas climate is defined as statistical weather information that describes the variation of weather at a given place for a specified interval. They are both used interchangeably sometimes but differ in terms of the length of time they measure and what trends affect them.

Weather is the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. In popular usage, climate represents the synthesis of weather; more formally, it is the weather of a locality averaged over some period (usually 30 years), plus statistics of weather extremes.”
