by Anura Guruge


Ice Out 1999 to 2021.

I take LEAP YEARS into account.
This year was NOT a LEAP YEAR.
So, April 5 this year,
in terms of days since Jan. 1,
is 94. If it had been a Leap Year
it would have been day #95.


Pretty amazing. Even earlier than last year — by two days. Coincidentally, it was again on a Monday. Monday’s, of late, have become a good day for ice-outs.

I had NOT expected this year to be this soon given that it was a COLD winter.

But, I know WHY we got this early date. WINDS. WINDS. WINDS. It has been a WINDY year. Last week we had unusually high winds. That is what broke up the ice.

is 96 — same as April 7
for a non-Leap Year.

So, this was EARLIEST since 2016.

Much earlier than the last two years.

Pretty early, but given the noticeably mild winter it was to be expected.

Not as early as 2016, 2012 or 2010. But, nonetheless, early.

Lake Winnipesaukee [NH] 2019 Ice-Out Was Wednesday, April 24 — @ 5:24am.

Prior instances when it was on April 24 (non-leap years)
and April 23 (leap years).

I take LEAP YEARS into account.
I count days from January 1, taking into account leap years.
So, April 21 & April 22 are 111-days in From Jan. 1
depending on whether it was Leap Year or not.

So, it wasn’t April 22nd as most people had expected. It was two-day later.

But, it was 2-days earlier than last year.

Same as 2015.

2014 was one-day off, but was also on a Wednesday.

Nowhere close to being even close to ‘long’. Longest was 132-days (since Jan. 1) in 1888.

Also, not the shortest. SHORTEST was just 3-years ago. 2016. 77-days, March 18,
