Why is the weather cooler in San Francisco then in other parts of California?

Answer 1

Its the fog, almost a daily occurence. If you go further North along the coast it gets even colder. I live 100 miles away in Monterey and we get the fog regularly too. You wont see the fog so much during the day but it just parks off the coast waiting for the evening so it can roll in along with a usually gentle breeze.

G'day Aubrey on Answers,

Thanks for your question.

It is the influence of its geography especially the Pacific Ocean.

A quotation incorrectly attributed to Mark Twain goes, "The coldest winter I ever spent was a summer in San Francisco." San Francisco benefits from California’s Mediterranean climate, characterized by mild wet winters and warm dry summers.However, surrounded on three sides by water, San Francisco's climate is strongly influenced by the cool currents of the Pacific Ocean which tend to moderate temperature swings and produce a remarkably mild climate with little seasonal temperature variation. Average summertime high temperatures in San Francisco peak at 70°F (21°C) and are 20°F (9°C) lower than they are in nearby inland locations like Livermore. Winters are mild, with daytime highs near 60°F (15°C), and lows almost never reach freezing temperatures. The months of May-September are quite dry, with rain a common occurrence from November-March. Snowfall is extraordinarily rare, with only 10 instances recorded since 1852.

The combination of cold ocean water and the high heat of the California mainland creates the city's characteristic fog that can cover the western half of the city all day during the summer and early fall. The fog is less pronounced in eastern neighborhoods, in late spring, and during September and October, which are the warmest months of the year. Due to its sharp topography and maritime influences, San Francisco exhibits a multitude of distinct microclimates. The high hills in the geographic center of the city are responsible for a 20% variance in annual rainfall between different parts of the city.They also protect neighborhoods directly to their east from the foggy and cool conditions experienced in the Sunset District; for those who live on the eastern side of the city, San Francisco is fairly sunny, with an average of 160 clear days, and only 105 cloudy days per year.

I have attached sources for your reference.

SF might want to be great if it did not value an arm and a leg to get a house the size of a storage contained in the midwest. the elements is sturdy, gentle and sunny specially and no iciness. i love it more desirable proper than San Diego, besides the undeniable fact that that's hotter in SD. probably you need to visit both, the subculture is diverse in southern california from northern california, some people basically look to bypass more desirable proper with one or the different.

Answer 5

B/c it's a peninsula. It has ocean on one side and a bay on the other. Most sea level water areas are naturally cooler. Add to that the wind created by the separation of the north and south shores of the bay inlet and viola! Cooler!

Answer 6

The ocean currents travel north south so the cold water helps keep the land cool. It is also surrounded by water so regardless there will be an offshore breeze from one side or the other. Then there is the fog which burns off in the morning returning at night.

Answer 7

because it is so close the bay area ocean, water that close makes the winds a lil stronger making weather way more cooler then parts of the bay rather then a city like San Jose which have no water near by!!

Answer 8

The Pacific ocean is nearby and controls the air temp due to the Pacific being so cool.

Answer 9

Its on the coast near the ocean, the farther north you go the farther away your from the warmer south pacific and mexico waters.

Answer 10

It sits on sort of a peninsula and catches the trade winds across the mountains from Oakland.
