Influence of Atlantic Winds

Galway’s coastal location heavily influences its cloud patterns. The city is situated on the edge of the North Atlantic Ocean, which releases vast amounts of moisture into the atmosphere. Westerly winds from the Atlantic carry this moisture eastward, leading to frequent cloud cover and precipitation. The movement of these winds also creates a dynamic interplay of cloud formations, with some dissipating quickly while others persist for hours or even days. As a result, Galway’s skies are constantly changing, from clear blue skies to dense cloud decks that obscure the sun’s rays.

Annual Rainfall

Galway, situated on Ireland’s western coast, experiences relatively high precipitation throughout the year. The annual average rainfall in Galway city is approximately 1,270 millimeters (50 inches). The western counties of Ireland, including Galway, receive the highest amount of rainfall, primarily due to the influence of prevailing southwesterly winds carrying moisture from the Atlantic Ocean.
