Best time to travel to San Francisco
The best time to visit San Francisco is during the fall (September to November) when the weather is warm and the famous fog, known as “Karl,” tends to clear, offering spectacular views. Spring (March to May) is also a great time, with blooming flowers and comfortable temperatures. Summer (June to August) is popular for visitors but can be surprisingly cool and foggy, so bring layers.
