The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography.

In summer, the Sun is continuously above the horizon for 57 days, from May 23 to July 19.

In winter, the Sun is continuously below the horizon for 35 days, from December 4 to January 8.

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 saving time are indicated by the "DST" labels.

Clouds

The median cloud cover is 82% (mostly cloudy) and does not vary substantially over the course of the year.

Median Cloud Cover

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 January 21, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 10% of the time, and overcast or mostly cloudy 18% of the time.

On September 18, the cloudiest day of the year, the sky is overcast, mostly cloudy, or partly cloudy 30% of the time, and clear or mostly clear 3% of the time.

Cloud Cover Types

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 probability that precipitation will be observed at this location varies throughout the year. Precipitation is most likely around October 16, occurring in 75% of days. Precipitation is least likely around July 6, occurring in 60% of days.

Probability of Precipitation at Some Point in the Day

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.

Over the entire year, the most common forms of precipitation are moderate rain, moderate snow, light rain, and light snow.

Moderate rain is the most severe precipitation observed during 33% of those days with precipitation. It is most likely around September 12, when it is observed during 39% of all days.

Moderate snow is the most severe precipitation observed during 24% of those days with precipitation. It is most likely around February 6, when it is observed during 36% of all days.

Light rain is the most severe precipitation observed during 21% of those days with precipitation. It is most likely around June 18, when it is observed during 22% of all days.

Light snow is the most severe precipitation observed during 17% of those days with precipitation. It is most likely around January 14, when it is observed during 21% of all days.

Types of Precipitation Throughout the Year

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

During the warm season, which lasts from June 18 to September 6, there is a 63% average chance that precipitation will be observed at some point during a given day. When precipitation does occur it is most often in the form of moderate rain (52% of days with precipitation have at worst moderate rain), light rain (33%), and drizzle (11%).

During the cold season, which lasts from November 16 to April 8, there is a 70% average chance that precipitation will be observed at some point during a given day. When precipitation does occur it is most often in the form of moderate snow (43% of days with precipitation have at worst moderate snow), light snow (27%), moderate rain (16%), and light rain (11%).

Warm Season Precipitation

Cold Season Precipitation

Relative frequency of various types of precipitation during the warm and cold seasons respectively.

Snow

The likelihood of snow falling is highest around February 6, occurring in 56% of days. The season in which it is relatively likely for snow to fall spans from October 11 to May 14.

Probability of Snow Fall Being Reported in a Given Day

Probability that snow will be reported at least once in a given day. The season is defined as the period during which the probability is greater than one third the maximum probability.

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

Humidity

The relative humidity typically ranges from 57% (mildly humid) to 90% (very humid) over the course of the year, rarely dropping below 39% (comfortable) and reaching as high as 100% (very humid).

The air is driest around May 16, at which time the relative humidity drops below 68% (mildly humid) three days out of four; it is most humid around August 31, exceeding 87% (very humid) three days out of four.

Relative Humidity

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 year, the dew point typically varies from 18°F (dry) to 51°F (very comfortable) and is rarely below 5°F (dry) or above 56°F (comfortable).

The time of the year between July 15 and August 16 is the most comfortable, with dew points that are neither too dry nor too muggy.

Dew Point

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 the year typical wind speeds vary from 2 mph to 18 mph (light air to fresh breeze), rarely exceeding 31 mph (strong breeze).

The highest average wind speed of 13 mph (moderate breeze) occurs around January 24, at which time the average daily maximum wind speed is 18 mph (fresh breeze).

The lowest average wind speed of 7 mph (light breeze) occurs around August 11, at which time the average daily maximum wind speed is 12 mph (gentle breeze).

Wind Speed

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 direction is highly variable and is not predominantly from any single direction.The wind is least often out of the north west (4% of the time), south west (4% of the time), and north (5% of the time).

Wind Directions Over the Entire Year

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

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.
