# 2 What is climate?

To define climate, one must first define ‘weather’.

‘Weather’ is the state of the atmosphere – such as temperature, rainfall, humidity, pressure, wind speed, sunshine and cloud cover – at a particular time and place. Scientists measure weather with instruments such as thermometers, rain gauges, anemometers and barometers. We can sense it with our skin, eyes and ears.

But climate is different.
