Orange is a city located in Orange County, California. It is approximately 3 miles (4.8 kilometers) north of the county seat, Santa Ana. Orange is unusual in this region because many of the homes in its Old Town District were built before 1920. While many other cities in the region demolished such houses in the 1960s, Orange decided to preserve them. The small city of Villa Park is surrounded by the city of Orange. The population was 138,669 as of 2019.Old Towne, Orange Historic District, a one square-mile around the original plaza, contains many of the original structures built in the period after the city’s incorporation. It is a vibrant commercial district, containing Orange County’s oldest operating bank and the oldest operating soda fountain. The Historic District was listed on the National Register of Historic Places in 1997, and is the largest National Register District in California. The Old Towne Preservation Association is a non-profit organization dedicated to maintaining the district.
The Orange County 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 1 °F per mile (0.3 °C/km) from the coast inland. California also has a weather phenomenon called “June Gloom” or “May Gray,” which sometimes brings overcast or foggy skies in the morning on the coast, but usually gives way to sunny skies by noon, during late spring and early summer.
