If you're talking about the conditions outside right now, that's weather. But if you're talking about the usual conditions of a place year after year, that's climate! Climate is the average weather in a location over a long period of time. For example, the climate in Miami is warm and sunny, even though the weather there today might be cold and rainy.
Scientists that study climate are called climatologists. They want to understand how climate works, what it was like in the past, and what will happen in the years to come.
