San Diego, California Weather and Climate
General & Geography
With around 1.4 million inhabitants, short for SD by abbreviationfinder, San Diego is the second largest city in the US state of California after Los Angeles and the eighth largest city in the United States of America.
The metropolis extends to a total of 963.6 km² and is home to more than 1.4 million people. In California, due to its proximity to Mexico, many residents speak Spanish as well as English. Hispanics make up around 30 percent of the population in San Diego.
San Diego is located in the outer southwest of the United States. It borders the Pacific Ocean to the west and the Anza Borrego Desert Park to the east. Mexico (Tijuana) begins about 30 minutes further south.
Climate in San Diego
Due to its location directly on the Mexican border, the climate is warm and dry with a few exceptions. The warmest months are July to October. Due to the proximity to the desert, warm air flows into the city again and again. The average temperature in the summer is 25 degrees. Even in the period from November to April, the temperatures in San Diego are still around 19 degrees.
Large fluctuations are not to be expected, rain and storms are comparatively rare. The sun, on the other hand, shines all year round. Around 300 sunny days make the city a paradise for all summer lovers. The water temperature is around 21 ° C at the end of August.
In the city center and east of San Diego it is usually a little warmer than on the coast. On some days between May and August in the San Diego region, a special phenomenon can occur: the marine layer, an air mass that forms over large areas of the sea. Here, warmer amounts of air meet the coolness of the water and cover the landscape like a thin mist.
When is the best time to visit San Diego?
In principle, one can say that the summer months have the warmest temperatures and are pleasantly dry. Between May and October there is hardly any significant rainfall, the conditions are usually ideal for excursions and exploring the region. However, the water temperatures are only suitable for bathing from around the beginning of June.
We therefore recommend June up to and including October as the best travel time for San Diego. The main season, with a correspondingly large number of visitors and sometimes very high hotel prices, are the months of July and August. It gets very busy around Independence Day in early July. From September the number of tourists slowly declines, which is why the peripheral months of May, September and October are particularly popular.
