Lima's barometric pressure is typically high, averaging 1013 millibars. This is due to its coastal location and proximity to the equator. The pressure remains relatively consistent throughout the year.
Lima is situated in a coastal valley surrounded by the Andes Mountains to the east and the Pacific Ocean to the west. The valley's unique shape and the cold Humboldt Current influence the atmospheric pressure. The Andes block moisture from the east, preventing significant rainfall. The cold ocean current keeps the air temperature mild and stable.
The city's landscape also affects the pressure. The valley's narrow shape and surrounding mountains create a microclimate. This microclimate helps maintain the high pressure and contributes to Lima's perpetual cloud cover. The stable atmosphere and low precipitation characterize Lima's weather.
