The park calls winter a perfect time to see the Gateway Arch: in January and February there are no lines for the trams and no waits for the films, and prolonged extreme cold is rare, though the daily mean temperature is only about 29°F. The museum under the Arch keeps its shorter off-season schedule, and the whole site shuts for the first day of the year.
