The Los Angeles area is also subject to the phenomena typical of a microclimate. As such, the temperatures can vary as much as 18 °F (10 °C) between inland areas and the coast, with a temperature gradient of over one degree per mile (1.6 km) from the coast inland. California has also a weather phenomenon called "June Gloom or May Grey", which sometimes brings overcast or foggy skies in the morning at the coast, but usually gives way to sunny skies by noon, during late spring and early summer.
