What Is The Best Time To Visit San Francisco

I’m planning a trip to San Francisco and I’m trying to figure out the best time to visit. I’m looking for a time that has the best combination of weather, attractions, and activities. I’m hoping to find a time when the weather is pleasant, attractions are open, and there are plenty of activities to do. I’d like to avoid times when the weather is too hot or too cold, attractions are closed, or there’s not much to do. I’m also looking for a time when the city isn’t too crowded or too expensive. Any advice on the best time to visit San Francisco would be greatly appreciated!
