The Los Angeles metropolitan area is noted for its year-round moderate to warm weather. The climate is classified as a Mediterranean climate, characterized by seasonal changes in rainfall with a dry summer and a winter rainy season but relatively modest transitions in temperature.
The Los Angeles area is also subject to the phenomena typical of a microclimate. As such, the daytime temperatures can vary as much as 36 °F (20 °C) between inland areas such as the San Fernando Valley and San Gabriel Valley versus the coastal Los Angeles Basin.
