The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time and climate is how the atmosphere behaves over relatively long periods of time.
Weather is the mix of events that happen each day in our atmosphere including temperature, rainfall and humidity, weather is not the same everywhere. Perhaps it is hot, dry and sunny today where you live, but in other parts of world it is cloudy, raining or ever snowing.
Climate is the average weather in a location over a long period of time. A place that doesn’t get much rain over many years would have a dry climate. A place where it stays cold for most of the year would have a cold climate.
