Conversely, the driest months are usually during the summer, from June to September, when high pressure systems dominate.

Factors Influencing Rainfall

The primary factor influencing rainfall in Glendale is its proximity to the Pacific Ocean. The city’s position in the prevailing wind patterns results in the moisture-laden air from the ocean being carried inland, where it cools and condenses, leading to precipitation. Additionally, Glendale’s elevation, at approximately 340 meters (1,100 feet) above sea level, contributes to the formation of clouds and precipitation. The city’s location within the Sonoran Desert also influences the rainfall patterns, as the desert’s arid conditions tend to limit precipitation.

Impact of Snowfall on Glendale

Despite its rarity, snowfall has a significant impact on Glendale. When snow accumulates, it can disrupt transportation, close schools and businesses, and lead to power outages.

Physical Characteristics and Notable Features

Glendale, California, is primarily characterized by its flat terrain. The city rests within the San Fernando Valley, a broad, gently sloping valley bounded by the Santa Monica Mountains to the south and the San Gabriel Mountains to the north.
