It suggests being aware of the prevailing circumstances and adjusting your actions accordingly.
Here's how it relates to wind:
* Wind direction: The direction of the wind can indicate the current weather pattern.
* Sailing: Sailors need to know the wind direction to set their sails correctly and navigate their boat.
* Metaphor: This metaphor applies to situations where you need to adapt to changing circumstances, similar to how a sailor adjusts their sails to the wind.
Examples:
* "After the first few weeks, the new CEO was starting to see which way the wind was blowing and made some changes to the company's strategy."
* "The political climate is shifting, so we need to see which way the wind is blowing before making any major decisions."
In short, "see which way the wind is blowing" means to be observant and adaptable to the current situation.
