How does the North Atlantic Current affect Ireland’s weather?

The North Atlantic Current, a warm, northeastward extension of the Gulf Stream, plays a fundamental role in maintaining Ireland’s temperate, western maritime climate.12

By transporting warm, saline waters from lower latitudes toward the high latitudes of the North Atlantic, the current acts as a significant heat source for the region. Prevailing southwesterly winds pick up this warmth and moisture from the ocean surface and carry them across Ireland. This process exerts an ameliorating effect on the country's weather, preventing the extremes of heat and cold that might otherwise be expected at such a northern latitude.3421

Consequently, Ireland experiences mild winters and moderate temperatures throughout the year, which contribute to the lush, green landscape for which the country is known. While the weather is often highly changeable due to the influence of Atlantic low-pressure systems, the consistent presence of the North Atlantic Current ensures that the climate remains equable and free from the severe, prolonged cold often found in other regions at similar latitudes.12
