Daily Sunrise & Sunset with Twilight and Daylight Savings Time in November

The solar day over the course of the year 2012 . From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (solar, civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight savings time are indicated by the "DST" labels.

Clouds

The median cloud cover is 84% (mostly cloudy) and does not vary substantially over the course of the month.

Median Cloud Cover in November

The median daily cloud cover (black line) with percentile bands (inner band from 40th to 60th percentile, outer band from 25th to 75th percentile).

On November 15, a representative day, the sky is clear or mostly clear 19% of the time, partly cloudy 19% of the time, and mostly cloudy or overcast 49% of the time.

Cloud Cover Types in November

The fraction of time spent in each of the five sky cover categories. From top (most blue) to bottom (most gray), the categories are clear, mostly clear, partly cloudy, mostly cloudy, and overcast. Pink indicates missing data. Outside of the United States clear skies are often reported ambiguously, leading them to be lumped in with the missing data.

Precipitation

The average probability that some form of precipitation will be observed in a given day is 73%, with little variation over the course of the month.

Probability of Precipitation at Some Point in the Day in November

The fraction of days in which various types of precipitation are observed. If more than one type of precipitation is reported in a given day, the more severe precipitation is counted. For example, if light rain is observed in the same day as a thunderstorm, that day counts towards the thunderstorm totals. The order of severity is from the top down in this graph, with the most severe at the bottom.

Throughout November, the most common forms of precipitation are moderate snow, moderate rain, and light snow.

Moderate snow is the most severe precipitation observed during 50% of those days with precipitation. It is most likely around November 30, when it is observed during 42% of all days.

Moderate rain is the most severe precipitation observed during 24% of those days with precipitation. It is most likely around November 1, when it is observed during 24% of all days.

Light snow is the most severe precipitation observed during 15% of those days with precipitation. It is most likely around November 23, when it is observed during 12% of all days.

Types of Precipitation Throughout November

Relative frequency of various types of precipitation over the course of a typical November.

Snow

The likelihood of snow falling is highest around November 30, occurring in 55% of days.

Probability of Snow Fall Being Reported in a Given Day in November

Probability that snow will be reported at least once in a given day.

Accumulation at this location in November is extremely unlikely. The chances of there being snow on the ground are highest around November 8, occurring 3% of the time.

Chance of at Least Some Snow on the Ground in November

The probability that there is snow on the ground.

The snow is typically at its deepest on November 30, with a median depth of 6.5"; the depth exceeds 7.0" only one year out of ten.

Snow Depth When there is Snow on the Ground in November

The median depth of snow during times when there is at least some snow on the ground, with percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th percentile).

Humidity

The relative humidity typically ranges from 66% (mildly humid) to 92% (very humid) over the course of a typical November, rarely dropping below 51% (mildly humid) and reaching as high as 100% (very humid).

The air is driest around November 29, at which time the relative humidity drops below 74% (humid) three days out of four; it is most humid around November 13, rising above 88% (very humid) three days out of four.

Relative Humidity in November

The average daily high (blue) and low (brown) relative humidity with percentile bands (inner bands from 25th to 75th percentile, outer bands from 10th to 90th percentile).

Dew Point

Dew point is often a better measure of how comfortable a person will find the weather than relative humidity because it more directly relates to whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid.

Over the course of a typical November, the dew point typically varies from 19°F (dry) to 32°F (dry) and is rarely below 10°F (dry) or above 40°F (dry).

Dew Point in November

The daily average low (blue) and high (red) dew point with percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th percentile).

Wind

Over the course of November typical wind speeds vary from 1 mph to 19 mph (light air to fresh breeze), rarely exceeding 29 mph (strong breeze).

The highest average wind speed of 10 mph (gentle breeze) occurs around November 30, at which time the average daily maximum wind speed is 19 mph (fresh breeze).

The lowest average wind speed of 9 mph (gentle breeze) occurs around November 17, at which time the average daily maximum wind speed is 18 mph (fresh breeze).

Wind Speed in November

The average daily minimum (red), maximum (green), and average (black) wind speed with percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th percentile).
The wind is most often out of the south (29% of the time), south west (15% of the time), north (11% of the time), and north east (11% of the time). The wind is least often out of the north west (2% of the time), south east (3% of the time), and east (5% of the time).

Wind Directions in November

The fraction of time spent with the wind blowing from the various directions over the entire year. Values do not sum to 100% because the wind direction is undefined when the wind speed is zero.

Fraction of Time Spent with Various Wind Directions in November

The fraction of time spent with the wind blowing from the various directions on a daily basis. Stacked values do not always sum to 100% because the wind direction is undefined when the wind speed is zero.
