FAQs About the City

Does San Francisco ever have shorts-and-T-shirt weather? 

Yes, but we can’t tell you exactly when, so come prepared. Our marine climate means mild year-round weather. August through October are usually the warmest months, but weather can change by the hour, so pack layers and a light jacket or coat for cool evenings. Temperatures seldom rise above 70°F (21°C) or fall below 40°F (5°C). Morning and evening fogs roll in during the summer months but rarely persist.
