Lake Winnipesaukee [NH] 2021 Ice-Out: April 4 — 14th Joint Earliest On Record; Even Earlier Than Last Year.

Ice Out 1999 to 2021.

Click to ENLARGE. Ice-out dates since 1999. Last column indicates # days into the year; i.e., days since January 1 of that year.

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.

Last Time Christmas Was On A Friday, As In 2020 — Was In 2015.

There would have been one in 2004
IF NOT for it having been a Leap Year.
Christmas, per the name ‘LEAP’,
jumped over Friday & took place on Saturday.


Last time we had Christmas, i.e., December 25th, on a Friday was in 2015 — 5-years ago.

6-year gaps are common. The cycle as to when the same date falls on a given day (e.g., Monday) goes in 6-5-6-11 cycle. You can see that in the image above — as to when Christmas has fallen on a Wednesday.

This 6-5-6-11 cycle has all to do with leap years. You can see that in the 2nd figure above.

The 5-year gap comes about when we have had TWO leap years, e.g., 1996 & 2000. In each case we LEAPT over a day (which is why we call it a Leap Year, i.e., because we leap over a day, in the calendar). Because of the two leap years, the gap was only 5-days. Then, between 2000 and 2006 there was only ONE leap year. So we only leapt over one-day. The gap was thus 6.

Next year, i.e., 2021, it falls on a Saturday — BUT the Friday, Christmas Eve will be a holiday.

Memorial Day 2020 — Early, As In May 25, But Not Unusual.

by Anura Guruge


Click to ENLARGE.



Prior to 1971, it was called ‘Decoration Day’ & always held on May 31st, irrespective of what day of the week it was.

As of 1971 it became ‘Memorial Day‘ & would be held on the LAST Monday of May.

Last Monday of May can fall between the 25th & 31st.

So, while May 25th may seem early — and it is (in that it is THE earliest it can now be) — it is not uncommon.

We had Memorial Day on May 25th just 5-years ago, in 2015. You can’t remember that?

And it was 6-years prior to that. Prior that that we had an 11-year gap.

Memorial Day falling on the 25th goes in those 5-6-11 year cycles. That is the same for all these types of fixed day events. 11-year gaps come about due to Leap Years.

We will have Memorial Day again on May 25th in 6-years time. Don’t forget.

This year was a LEAP YEAR.
So, April 6 this year,
in terms of days since Jan. 1,
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.

Last Time Christmas Was On A Wednesday, As In 2019 — Was In 2013.

Note how Leap Years break
up the sequence — hence the
name ‘Leap’, since days leap ahead.



Last time we had Christmas, i.e., December 25th, on a Wednesday was in 2013 — 6-years ago.

6-year gaps are common. The cycle as to when the same date falls on a given day (e.g., Monday) goes in 6-5-6-11 cycle. You can see that in the image above — as to when Christmas has fallen on a Wednesday.

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

by Anura Guruge


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,

Lake Winnipesaukee [NH] 2019 Ice-Out Expected To Be Monday, April 22.

Prevailing consensus is that it most likely will be April 22 in 2019. But, there could always be a pesky little floe floating around that could delay it by 12-, 24-, 36 or even 48-hours.

I am just going with the flow.

Lake Winnipesaukee [NH] Ice-Out: Longest [i.e., Latest] Occurrences.

by Anura Guruge



↑↑↑↑

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.

Lake Winnipesaukee [NH] Ice-Out: Earliest Occurrences.

2012 was a LEAP YEAR and I take that into account.
I count days from January 1, taking into account leap years.
So, March 24 in a non-leap year is the SAME as March 23 in a Leap Year.



So, of course, we have had ice-outs by now; viz. April 5.

And we don’t have to go to far. Just in the last 9-years, with 2016 THE RECORD since the 1887 — the first year for which we have reliable data.

I was in Wolfeboro two-days ago. The ice was very white and looked pretty solid.

Yesterday, the ice on The Broads looked black. That means it would typically break-up within 48-hours. I have seen it happen — ONCE. Magical. One second we have ice, the next it is ALL gone as far as the eye can see. This was in 1999 or 2000 when I was living waterfront in Gilford.

Mid-April might be good for this year too.

Lake Winnipesaukee 2018 Ice-Out — Latest Since 2001 & ANOTHER On A Thursday!

by Anura Guruge


Click to ENLARGE. The ebb and flow of ice-out dates 1988 to 2018.


Click to ENLARGE. Other ice-outs 115 days in. All on NON-Leap Years (and ‘1900’ was NOT a Leap Year). 4 on a Thursday.


Click to ENLARGE. Ice-out dates 1990 to 2018.


So Winnipesaukee ice-out 2018 was on Thursday, April 26 around 5:40pm.

> >  This was the LATEST ice-out since 2001 when the ice-out was on May 2 (and I remember that).

> >  Another ice-out on a Thursday. We have had more ice-outs on Thursday than any other day, BY FAR.

> >  Last time ice-out was on April 26 was in 1979, 39-years ago.

> >  All ice-outs that have happened 115-days into the year have happened on NON-LEAP Years, so all are on April 26. [115-days in on a Leap-Year would be April 25.]

> >  The average for ice-out was (and still is after this year) 108.2 days in; i.e., April 19 (non-Leap) & April 18 (Leap).

> >  Ice-out in 2003 was on April 25 (114 days). Ice-out in 2008 & 2015 was 113-days in (April 23 & April 24 because one was a Leap).

> >  Ice-outs in 2016, 2012 & 2010 were way below average.
