Bookmark & sharePick a month of the year and there's always a festival or street party on somewhere in San Fran. Unless a bit of fog or a brisk morning perturbs you, you can't go too wrong. The best months to come are either side of the summer peak season, with the September to November period being particularly festive.
Weather
San Francisco is a popular location any time of the year. Summer is the prime tourist season, but its summer weather is none too hospitable: the bay is often foggy, while inland or north in the Wine Country it's often too hot and dusty for comfort. Local weather patterns are highly unpredictable, but generally the best months weather-wise are between mid-September and mid-November.
