With the colder then average March we are having this year lets look back at a March that was much above average.
We generally do not think of the term “Heat Wave” when we think of the Month of March but in March of 2012 we had a very remarkable warm event take place. This was not a one or two day “warm” spell that we sometimes get in March but instead lasted for (at Grand Rapids) for 12 days. It started in earnest on March 14th when Grand Rapids had a high of 80° and for the next 12 days we had temps that would be more like June then March. Reaching a peak on March 21st with a high of 87° In all in that 12-day stretch Grand Rapids had 5 days of 80 or warmer 5 days of 71 or warmer and 2 days in the 60’s

The ‘Heat Wave’ of March 2012, By the Numbers
32 The gap, in degrees, between the old and new record high on March 21 in Marquette, Mich. The new record high was 81 degrees, obliterating the old record of 49 degrees. The margin of defeat was so great that the 21.2 The temperature departure (in degrees Fahrenheit) from normal for the month of March thus far in Winnipeg, Canada. This occurred despite temperatures having dropped below zero for four days early in the month.
1921 The last year it was above 80 degrees in Boston before March 28 of any given calendar year. In reaching 83 degrees on March 22, this came to fruition for the first time since March 21, 1921.
86 The new all-time record high temperature for March in Detroit, Mich., set on March 22. In fact, a new all-time high temperature was set two days in a row, with the mercury first climbing to 84 degrees on March 21.
60 The average low temperature in Chicago, Ill., from March 17 to March 22 of this year. Such low temperatures, about 30 degrees above normal, are more typical for mid-June.
e low temperature that day was even higher than the old record high temperature
9 The number of consecutive days that Chicago, Ill., has broken a record high, from March 14 to March 22. Eight of those days saw the mercury climb above 80 degrees, which is normal for mid-June.
93 The temperature swing that occurred over the course of just nine days in International Falls, Minn., from a low of minus 14 degrees on March 9, to a high of 79 degrees on March 18. Also, 10 straight days of new record highs (March 13 to March 22).
26 The number of inches of snow that melted over the course of just seven days in Caribou, Maine, from March 15 to March 22, thanks to the unusual warmth. Also, 18 inches of snow was still on the ground when the first record high fell on March 18 (64 degrees).
In Detroit, the mid-March heat wave was enough to vault the month to the top of the list of warmest Marches on record. Not only that, but the records for the most consecutive March days with highs above 60, 70, and 80 degrees were also set.
Of course there was a price for crops to pay as April 2012 ended up close to average and there was a hard freeze on April 29th when the temp fell to 28° causing a lot of damage to crops that year.
Grand Rapids is in record territory. The last time it reached 60 or better at Grand Rapids was back on October 14, 2018. That puts GR in 3rd place for the longest time between days that did not reach 60 or better. The longest was 183 days from October 13, 1925 to April 13, 1926 in 2nd place is 178 days from October 13 1969 to April 8, 1970 and this year so far we are now at 161 days and counting.. Note the earliest last 60 or better dates are October 13 1925 and 1969 and last year it was October 14 the 2nd earliest. On the warmest maximum contest for this March. Here are the temperature guesses. Rocky 49.4, Indy 57, Mark 59, MV 62, Mookie 62, Andy 65, Sandy 69, SS 70, Barry 71, Sarah 72 and my guess is 64. The warmest so far this March at Grand Rapids is 59° At Lansing it is 62 and at Muskegon it is 61. So with a week and a day to go the winner so far is Mark for Grand Rapids, Mookie would win for Lansing. We will see how the next week goes. This March will end up below average temp wise the question now is by how much.
