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 21% of the time, partly cloudy 16% of the time, and mostly cloudy or overcast 60% 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 79%, 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 rain and light rain.

Moderate rain is the most severe precipitation observed during 73% of those days with precipitation. It is most likely around November 1, when it is observed during 59% of all days.

Light rain is the most severe precipitation observed during 14% of those days with precipitation. It is most likely around November 17, 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 4% 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.

Either snow rarely accumulates at this location in November or snow depth measurements are unavailable or unreliable.

Humidity

The relative humidity typically ranges from 71% (humid) to 95% (very humid) over the course of a typical November, rarely dropping below 59% (mildly humid) and reaching as high as 100% (very humid).

The air is driest around November 1, at which time the relative humidity drops below 78% (humid) three days out of four; it is most humid around November 20, rising above 93% (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 35°F (dry) to 48°F (dry) and is rarely below 29°F (dry) or above 55°F (very comfortable).

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 5 mph to 20 mph (light breeze to fresh breeze), rarely exceeding 30 mph (strong breeze).

The highest average wind speed of 13 mph (moderate breeze) occurs around November 27, at which time the average daily maximum wind speed is 20 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 west (27% of the time), south west (20% of the time), and south east (12% 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.
