Yes, it is possible to see stars in the night sky in San Francisco. However, the visibility of stars can vary depending on various factors such as light pollution, weather conditions, and atmospheric conditions. San Francisco is a densely populated city with significant light pollution, which can make it more challenging to see stars compared to rural or less populated areas. Areas with less artificial lighting, such as parks or observatories outside the city, may offer better stargazing opportunities. Additionally, weather conditions like cloud cover can affect visibility. It's always a good idea to check weather forecasts and choose locations away from bright city lights for the best chances of observing stars in any urban area.
