What San Francisco's weather means for companies
Winters are mild in San Francisco, with January averaging a high of 58°F, but highs stay under 65°F from November to May, so a quarter-zip or light soft shell is the office layer for half the year or more. Highs reach 70°F or more only from September to October, a short window for outdoor offsites, so schedule them early and pair event tees with a long sleeve. Mornings stay cool for much of the year, with January lows around 47°F, so a soft shell or quarter-zip over the polo works for site visits and commutes. December brings about 4.8 inches of rain, the most of any month, so water-resistant jackets for field staff are worth ordering before it arrives.
