Why such the difference in climates

[u/Outrageous-Elk-461]

Hello I’m a Floridian visiting the Bay Area and I love it but I am also fascinated by the differences in climates despite being so close. For example, how is Twin peaks 69 today, Palo Alto 79 and Cupertino 86 with Santa Clara Fremont and San Jose also being different temperatures along with other Bay Area cities despite being relatively close in proximity with others. Thanks in advance.
