Continue on Oroville Dam Blvd., turning right at Olive Hwy. Turn left and Kelly Ridge Road ends in the Visitor Center parking lot. Winter months are cool to cold, seldom freezing temperatures, and some occasional fog. Temperatures run from mid to high 50s down to the 30s. Springtime is beautiful with a vivid array of wildflowers and very pleasant temperatures, normally in the high 60s to 70s.
Summers are warm to extremely warm.
The temperatures range from the low 80s up to the low 100s. Fall season usually brings a little humidity, but not much. Bring appropriate clothing to fit the season. Campers should bring sweatshirts during the summer months, because it can get somewhat cooler in the evenings and out on the water. Layered clothing is advised.
