[2] Precipitation runoff from the south side of the peak as well as meltwater from the Platform Glacier drains into headwaters of Fitzsimmons Creek which is a tributary of the Green River.

Topographic relief is significant as the summit rises 1,170 metres (3,838 ft) above Fitzsimmons Creek in three kilometres (1.9 mi).

[5] Most weather fronts originate in the Pacific Ocean] and travel east toward the Coast Mountains where they are forced upward by the range (orographic lift), causing them to drop their moisture in the form of rain or snowfall.

As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall.

The months of July and August offer the most favorable weather for climbing Shudder Mountain.
