Lake Winnipesaukee [NH] Ice-Out: Longest [i.e., Latest] Occurrences.
1964 was a LEAP YEAR and I take that into account.
I count days from January 1, taking into account leap years.
So, April 29 in a non-leap year is the SAME as April 28 in a Leap Year.
So, of course, we have had ice-outs as late as May 12 — albeit not of late.
2018 [i.e., last year], on April 26, was pretty late. Don’t think it will be as late this year. But, I suspect we are still at least a good week away.
