Weather is what the air outside is like each day. It can be sunny, cloudy, rainy, windy, foggy or snowy, and it can be hot, warm, cool or cold. The weather can change from morning to afternoon, so people check the weather forecast to plan what to wear and do.
We can measure the weather. A thermometer measures temperature: how hot or cold it is. A rain gauge collects rain to measure how much fell. A wind sock or a weather vane shows which way the wind blows. Recording the weather in a chart each day helps us spot patterns, like more rain in some months.
