San Francisco moved into California’s purple Covid-19 tier on November 28. A (limited) curfew has been imposed from November 30 to December 21. This means that outdoor gatherings are not allowed between 10:00 p.m. and 5:00 a.m. You are still allowed to be outside, alone or with people from your household, and you are still allowed to travel to or from an essential job at these hours. More detail on what is and is not allowed can be found here: https://sf.gov/news/sf-assigned-states-purple-tier-will-roll-back-many-non-essential-activities . With increasing cases and hospitalizations, another order, with additional restrictions, was issued on December 4: https://www.sfdph.org/dph/alerts/files/C19-07-Shelter-in-Place-Health-Order.pdf .
