November by the Numbers

Hurricane Sandy is long gone, but its effects will be felt for quite some time. Many people are still without power today, including those in homes and businesses throughout southwestern Connecticut. Now, it's time to look ahead to November and how the month shapes up climatologically. Don't forget to "fall back" this weekend. Standard Time begins this coming Sunday morning, November 4, at 2 o'clock.

Snow is certainly not out of the question during this month. Perhaps the most memorable Thanksgiving Day in recent memory occured in 1989 when over a half-foot of snow fell that day. The snow began falling shortly after midnight, and by the time it ended late Thanksgiving afternoon, it was the biggest single-day snow event in November.

Snow also fell twice in 1995, including 2.4 inches on November 29 of that year. That was the snowiest Winter on record across southwestern Connecticut. Another "snowstorm" of note happened on November 6 and 7 of 1953 when a combined 5.4 inches fell. However, the average snow for the month is only 0.6 inches.

November can also be a wet month, too. The most precipitation in November occured in 1972 when 10.22 inches were recorded. There have also been some impressive single-day totals, including 3.12" (Nov. 2, 1954), 3.04" (1972), and 2.91" (Nov. 10, 1948). The average precipitation for the month is 3.81 inches, ranking it fourth behind March, May, and April as the wettest months of the year. The driest November happened 36 years ago when only 0.36" fell in 1976.

We begin to experience a dramatic decline in average temperatures, too. At the start of the month, the normal high and low are 59 and 43 degrees, respectively. However, by month's end, the normals are 47 and 33. That's an 11-degree drop in the mean temperature. The average high temperature is 53 degrees, while the average low for the month is 38.2 degrees.

The warmest November on record occured in 1975 when the average temperature was a relatively balmy 50.5 degrees. The coldest November happened 15 years ago, in 1996, when the mercury averaged 40.7 degrees. Although the temperature has never officially reached 80 degrees at the airport during the month, we've come close a few times. The warmest single day reading was 78 degrees which happened twice, on Nov. 4, 1975, and Nov. 15, 1993. Other notable warm days include 77 degrees (Nov. 2, 1950), and 72 degrees (Nov. 5, 1961).

The length of daylight continues to decrease with each passing day. We're a little more than seven weeks from the Winter Solstice, which is the shortest day of the year. By the middle of the month, Sunrise and Sunset are at 6:41 a.m. and 4:33 p.m., respectively. By the last day of the month, the Sun rises at 6:58 in the morning and sets at 4:24 in the afternoon. That's only one minute later than the earliest Sunset, at 4:23, in early-to-mid December.

The Full Beaver Moon happens November 28 at 9:46 a.m. EST. Why the Beaver Moon? This was the time to set beaver traps before the swamps froze, to ensure a supply of warm winter furs. Another interpretation suggests that the name Full Beaver Moon comes from the fact that the beavers are now actively preparing for winter. It is sometimes also referred to as the Frosty Moon.

Welcome to November.
