What March is like
March is a gamble. A snowstorm and a 60-degree day can arrive in the same week. The ice on the St. Croix weakens and breaks up, the Mill Stream runs loud with meltwater, and sandhill cranes return with their rattling calls over the fields. Trails are often icy in the morning and muddy by afternoon.
In March, Marine on St. Croix averages a high of 41°F and a low of 23°F. Expect about 2.1 in of precipitation (liquid equivalent) and roughly 7 in of snow. About 24 nights dip to freezing. Days last about 12.0 hours, with roughly 8.3 hours of sunshine.
The river in March
Long-term average flow at St. Croix Falls in March is 4,391 cfs — close to the yearly average.
