Dear Tom,
Does Hudson Bay in Canada freeze over completely? How thick does the ice get there?
— Patrick Carry, Waukegan
Dear Patrick,
Based on aerial and satellite observations, ice formation in Hudson Bay typically begins in mid-October and steadily increases through early winter.
It is nearly 100 percent ice-covered in most winters from January into April.
As spring progresses, the ice begins to break up and typically melts by late August.
In most winters, the ice become quite thick, reaching an average of 4 to 5 feet by early April.
A check of charts from Environment Canada confirms that Hudson Bay is currently almost totally ice-covered.
