Like most of coastal Iceland, Vík í Mýrdal has a subpolar oceanic climate with cold but not severe winters and cool, short summers. Because it lies on the windward side of the Gulf Stream, Vík í Mýrdal is the wettest coastal town in Iceland, with an annual rainfall of 2,275 millimeters (90 in), which is three times more than Reykjavík and five times more than Akureyri on the northern side of the island. Precipitation on the Mýrdalsjökull and Vatnajökull glaciers near the town is believed to be as high as 160 inches (4,064 mm) of rainfall equivalent, which would mean at least 160 feet (48.8 m) of snow at those higher altitudes
