Google-search – What direction is north in the wind arrows in weather.com

google-search

When searching "weather" in Google, in my country Argentina, (I hope you can access that link "as is" no matter what country are you) a weather.com special box appears on Google results:

WA101963 question first example

I click "Wind" and then a number of arrows indicating, I guess wind direction and speed are shown:

Considering 8 pm: ESE is conventionally (for meteorologists) the from:

Wind direction is where the wind is coming from. If the weatherman (or weatherwoman) says that the wind is southwesterly, that means that the wind is blowing FROM the southwest.

the head of the arrow or cockerel (or equivalent depending on the chosen design) will indicate the direction from which the wind is blowing.

However, there is also a convention that for one way traffic etc any arrow points in the direction of flow (the to direction) and Google (IMO very sensibly) have chosen that one. Scope for confusion is indicated (!) here for example.

So, from BA, an arrow this way up means the wind is blowing towards Paraguay - it's North.
