May climate

May marks the beginning of the growing season in New York State, and although below freezing temperatures are almost a certainty in our area, they normally occur during the first half of the month. Frosty nights, however, can be expected throughout May and even in early June in the Adirondacks.

For the past 38 years, the dates of the last freezing temperature in Malone vary from as early as April 22nd in 2011 to as late as June 3rd in 1986. The average date of the last frost is May 10th.

Although May can get pretty hot locally, as evidenced by the record-setting 94-degree reading last year, in a normal May, we can expect one day with a maximum reading above 80 degrees and another seven days with a maximum above 70.

The coldest May temperature over the past 38 years was a 24-degree reading on May 3, 1986. Normally we can expect 2-3 days with minimums of 32 degrees or below.

We often receive a trace of snow in May, but occasionally we receive a measurable amount as was the case on May 9th and 10th, 1983, when nine inches fell in Malone, and in 1996 when 5 1/2 inches fell on Mother’s day (May 12th).

Normal precipitation for May is 3.10 inches. Over the past 38 years the most was 7.11 inches in 2011 and the least was 1.45 in 2016.
