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.
