When flights get cancelled because of heavy winds / bad weather, why is it only e.g. 10% of all flights and not 100%? Isn’t either too dangerous so no plane can take off or it’s safe so they all can take off ?

Going to add into what has already been mentioned…

SFO has two parallel runways. It’s scheduled to use both. However, there are times where they cannot safely use both and close one runway. Either visibility or crosswinds. (Annoyingly, one of the common situations is fog reducing visibility… Fog. In San Francisco.) The airport is still operating but any lower priority flight is delayed until it clears. I worked for an airline that had a very small presence in SFO – we had a lot of delays.

I’m sure there are other airports that semi regularly have to close one of their runways due to weather for various reasons.
