The weather in August in America

I know that in San Francisco and Los Angeles, the temperature is about 25 to 30 degrees Celsius. The temperature difference between day and night is quite large. It's hot when the sun is on, and cool when the sun is off. San Francisco is a windy place. It is recommended to add a thin windbreaker to the T-shirt. If you are afraid of the sun, a long-sleeved light-colored blouse is also a good choice. There is no windbreaker in Los Angeles. Short sleeves are most suitable. Basically it won't rain. Feel the sunshine in California!
