Based on the Köppen climate classification, Shakespeare Shoulder is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. Winter temperatures can drop below 0 °F with wind chill factors below −10 °F. This climate supports the Shakespeare Glacier on the west slope of the mountain and the massive Whittier Glacier (named for John Greenleaf Whittier) on its southern and eastern slopes. The months of May and June offer the most favorable weather for viewing and climbing this mountain.
