Riquewihr's climate is generally dry and sunny. The Vosges mountains block the oceanic disturbances from the west and create weather favorable to the cultivation of vines. The annual average temperature is around 50 ° F (10.5 ° C). July is the hottest month with an average of 67 ° F (19.7 ° C), and January is the coldest (34 ° F / 1.5 ° C). The cooling of lower layers of the atmosphere in contact with the ground sometimes forms mists that cover Riquewihr and its surroundings. The ridgeline of the Vosges isolates the village, and the winds are generally calm and unlikely to damage the vines.
