"It is not raining" means that there is no precipitation falling from the sky at a given time. This condition can be observed when the atmosphere is dry, and clouds are either absent or not producing rain. Weather conditions can vary, and the absence of rain can be influenced by factors such as temperature, humidity, and air pressure. When it is not raining, outdoor activities can be more enjoyable, as people can engage in various pursuits without the inconvenience of getting wet. This weather condition is often associated with clear skies or partly cloudy conditions, which can also lead to sunshine and warmer temperatures, making it ideal for activities like picnics or sports.
