DID YOU KNOW?
Many people confuse Weather and Climate, but they are different. Weather refers to the conditions of the atmosphere over a short period of time, while Climate refers to the conditions of the atmosphere over a long period of time.
Weather, more specifically, refers to how the atmosphere behaves and its effects on life and human activities. Most people think of Weather in terms of what can be observed: temperature, humidity, precipitation, and cloudy/sunny conditions. Weather conditions constantly change on a minute-to-minute basis.
Climate is a record of the average weather conditions for a given place over a long period of time, often referred to as Climate Normals. A 30-year period of record is a common requirement to be considered a Climate Normal.
