Lake Nipissing Ice Free Dates Statistics

Statistical Analysis for Central Tendency of Lake Nipissing Ice-free Dates 
Updated May 17, 2014

Dates were converted to days after March 31. (For example May 6 is 36 days after March 31.)
 
The overall average date is 28.1 days after March 31, thus April 28.
The median (middle value of ranked dates) is also April 28.
  
The standard deviation is plus or minus 8.9 (or 9) days. The "average range" is by definition the statistical range between +1 and -1 standard deviations and contains 68% of all dates. The average range lies between April 19 and May 7.

Statistically, the "best guesses" for ice-off dates are between April 19 and May 7, with April 28 in the middle.

Since the year 2000, there have been 4 ice-outs after April 28 and 9 before, and 1 actually on April 28. Despite the very cool and late spring in 2014, there is a trend towards earlier than average ice-out dates. The average date has shifted slightly earlier from 28.4 to 28.1 days after March 31.

Now, place your bets for the 2015 ice-free date!
