The city's location in a valley affects the pressure. York is surrounded by mountains to the north and west. These mountains block air masses from the Atlantic Ocean.
As a result, the air is drier and cooler than in coastal cities. The mountains also force warm air to rise, cool, and condense. This creates precipitation.
The city's landscape also features rolling hills and flat plains. These terrain features influence local wind patterns. They direct winds from the west and southwest, bringing warm air from the Gulf of Mexico.
