While Miami has never officially recorded any accumulating snowfall since records have been kept, there were non-accumulating snow flurries in some parts of the city on January 19, 1977 during the cold wave of January 1977.[7][8][9] Weather conditions for the area around Miami were recorded sporadically from 1839 until 1900, with many years-long gaps. A cooperative temperature and rainfall recording site was established in December 1900 in what is now Downtown Miami. An official Weather Bureau Office opened in Miami in June 1911.[10] A record setting 12-day cold snap in January 2010 was the coldest period since at least the 1940s.[11]
