Seasons in California

California it the most populated and third biggest state in USA. It is situated in western part of the country and washed by the Pacific Ocean. Relief of the state varies greatly. Central part of the California is vast Central Plain surrounded by mountains: Pacific Coast Ranges on west, Sierra-Nevada on east, Cascade Range on north and Tehachapi Mountains on south. Also there are desert in south-eastern part of the state.

Climate of coastal areas of California is formed under influence of the Pacific Ocean while weather conditions of inland territories depend on features of relief. Most of the state has Mediterranean climate with moderate temperature ranges of dry summer and rainy winter. Due to brier effect of mountains humid air from above the ocean cannot reach inland territories resulting wider ranges of temperature.



Spring in California

In early spring northern half of the state stays cool with daily range of temperature between 62 °F (17 °C) and 39 °F (4 °C). Elevated ski resorts may remain open until April, but in regions with lower altitude melting snow feeds waterfalls and they shine. Meantime in wine country there is vigorous vegetation of vines.

Central plain has around 66 °F (19 °C) in April but, by May temperature rises to 80 °F (27 °C). Spring in southern regions is one of the most pleasant seasons before summer humidity brings overcast and fogs. In late May southern California falls under June gloom with overcast and cooler weather.
