Southern Oregon Coast Range - Location and Climate

Location and Climate

The range begins around the Umpqua River with the Central Oregon Coast Range to the north. Oregon Route 38 is the general divide between the two sections. On the southern end the Coquille River’s middle fork provides the general dividing line between the Central Range and the Klamath Mountains to the south and east.

The climate of the mountains is of the mild maritime variety. It is characterized by cool dry summers followed by mild and wet winters. Most precipitation falls in the form of rain, with snow during the winter months at the higher elevations. Annual precipitation varies from 60 to 120 inches (150-300 cm), with more in the higher elevations. The average high temperature in January is 36.3°F (2.4°C), and the average high in July is 61.9°F (16.6°C) with temperature also varying by elevation.
