Use the noun foresight to describe successful planning for the future, like on a cloudy morning having the foresight to bring an umbrella in case of rain showers later in the day.
The word foresight is made of two parts: fore, which means "before," and sight, which means "to perceive." People often perceive things with their eyes: this is vision, or sight. But vision also describes what someone thinks will happen. So foresight is planning for things before they happen.
