Hi we want to visit Harbin this late of march 2015.

Oh, according to the previous statistics, the temperature during that period of time is 14 F to 57.2 F. The temperature has gone up again. It will hardly see snow then.
Generally speaking, the ice festival and ice sculptures will end at the beginning of March.

It is the end of winter and the beginning of spring. There might be light snowfall in the beginning of March. March is still cold, with low humidity, but it is sunny. It is too warm for the winter festivals. The average nightly low temperature is -10 °C (14 °F), and the average daily high temperature is 2 °C (36 °F).

There is a temperature drop from day to night of 12 °C. It snows or rains about 6 days a month, but the monthly precipitation is slight (11 mm). Though it is freezing, it is usually sunny. People enjoy about 8 hours of sunshine a day.
