Climate - The area receives a high amount of precipitation. Much of the precipitation comes from October to April in the form of rain at the low elevations and as wet heavy snow in the higher elevations. Winter temperatures are normally cool at the lower elevations and cold at the higher elevations. Although snow is possible in the lowest elevations, it is infrequent and does not stay on the ground for long. Late spring, summer and early autumn bring the best chance for clear, sunny days and bring moderate temperatures.
