San Diego Has A Desert Climate, Not A Tropical One
There is a myth that San Diego is a tropical climate. The beaches and palm trees paint the illusion that this is the Caribbean or South Pacific. In reality, San Diego is a desert right up to the ocean. This means it is warm in the daytime and cool at night. As a result, the temperatures fluctuate as much as 25 degrees between daytime and nighttime.
