How close to the equator has snow fallen (at sea level, not on mountaintops)?
Several tropical locations have reported snow at sea level, including near Nanning, China, in 1654; in Hong Kong in January 1893; and in Tampico, Mexico, in February 1895. The 1654 Chinese snowfall, near the present-day coastal city of Beihai, was nearest to the equator, at 21 degrees, 29 minutes north latitude. Several centimeters of snow were recorded there. The southernmost sea-level snow report in the USA was at Homestead, Fla., (at 25 degrees, 28 minutes north) in January 1977. South of the equator, at 33 degrees, 2 minutes south latitude, Valparaiso, Chile recorded snow in July, in what may be a southern-hemisphere record.
