Its nearest higher peak is Mount Marriott, 5.43 km (3 mi) to the north-northeast.

[3] Precipitation runoff from the peak drains into Cayoosh Creek and other tributaries of the Fraser River.

[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 July through September offer the most favorable weather for climbing Cayoosh Mountain.
