2021 Ice-out was recorded as 4/5/21. Total 2020 winter ice days were 111 days with the average amount of days of ice being 130.962. The ice went out this spring 16 days earlier than the average ice-out date. This is an early spring and you'll get your dock and boat in early, but it is not Lucerne's earliest. Spring of 2000 holds the record of the shortest, 97 days of ice. Spring of 2012 holds the earliest, March 21, 2012 has been the ONLY March ice-out date!

My 2021 Winter Ice-in calculations are figured as follows:

As of last year data, the average amount of elapsed days to ice-in after New Years Day is 344.23 days, which equates to an ice-in date of 12/11/21 @ 10:09 AM. (This is probably the best computation as it's based on the calendar.)

As of last year data, the average amount of water days after the previous ice-out date is 130.962 days, which based on the ice-out date for 2021 (4/5/21) equates to an ice-in date of 11/25/21 @ 10:37 AM.

An absolute average of these dates would be 12/3/21 @ 10:23 AM. Science, Al Gore and John Kerry have nothing to do with this, it is merely numbers. When God decides on ice-in, it will happen, and the Cardinals will announce it via the Knottlane Sap Shack smoke. AOC and the left will then declare that the early or late date is due to climate change!

Average Days of ice , as of 2020 130.962

Average Ice-out Date is: April 21

Average Days of water, as of 2020 233.797

Average Ice-in Date is: December 11

Ice dates are a consortium of Lake Lucerne Cardinals: Shirley Ratty, Meg, Andy, aLf - (Cardinal-Emeritus) and other Loons & Loonies.
In 2017, the Knottlane Cardinals were awarded the highly sought after Lake Lucerne loon pin of Excellence.
