Weather in San Diego

San Diego is located on the Pacific Ocean and is the second largest city of the state of California belonging to the country of United States of America (USA).  The city has a population of 1,359, 132 and is named after Saint Didacus.  <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />San Diego lies upon an elevated area of land within deep canyons and hills.  The San Diego River runs through the city separating it into northern and southern areas.  The city has more than 100 neighbourhoods.  The weather in San Diego is of an arid-mediterranean climate enjoying mild sunny weather all year.  The weather can vary quite significantly in different areas of the city due to its topography of the bay, hills, mountains and canyons.  San Diego has its own micro-climate especially in the months of May and June when a thick marine layer of cloud near the coast will keep the air cool and damp yet, within a few miles of the coast sunshine will prevail without any cloud in the sky.  The weather is mainly affected by the: distance from the northern storm tracks and southern storms of northern Californian coast; proximity to the ocean to the west; mountains in the east and the Colorado desert further east.   San Diego is not an area of annual storms / hurricanes as cold Californian current keeps the ocean colder than the Gulf of Mexico so most hurricanes disperse over California and fail to significantly affect San Diego, although there have been 2 hurricanes in recent years which have affected this city, the California Tropical Storm of 1939 and Hurricane Kathleen of 1976.   There are âSonorasâ which occur a couple of times per year which are storms from the south but they do not have a great affect on the climate as are low energy and do not really affect the weather.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
