Sun

The length of the day varies significantly over the course of the year. The shortest day is December 21 with 0:00 hours of daylight; the longest day is June 20 with 24:00 hours of daylight.

Due to its extreme latitude, Evenes experiences polar day (also known as the midnight Sun) during summer and polar night during winter. 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 55 days, from May 24 to July 18.

In winter, the Sun is continuously below the horizon for 34 days, from December 4 to January 7.

Daily Hours of Daylight and Twilight

The number of hours during which the Sun is visible (black line), with various degrees of daylight, twilight, and night, indicated by the color bands. From bottom (most yellow) to top (most gray): full daylight, solar twilight (Sun is visible but less than 6° from the horizon), civil twilight (Sun is not visible but is less than 6° below the horizon), nautical twilight (Sun is between 6° and 12° below the horizon), astronomical twilight (Sun is between 12° and 18° below the horizon), and full night.

Daylight savings time (DST) is observed in this location during 2012, starting in the spring on March 25 and ending in the fall on October 28.

Daily Sunrise & Sunset with Twilight and Daylight Savings Time

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 86% (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 February 18, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 13% of the time, and overcast or mostly cloudy 23% of the time.

On September 30, the cloudiest day of the year, the sky is overcast, mostly cloudy, or partly cloudy 37% of the time, and clear or mostly clear 4% 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 2, occurring in 75% of days. Precipitation is least likely around July 6, occurring in 62% 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 light rain, moderate rain, moderate snow, and light snow.

Light rain is the most severe precipitation observed during 28% of those days with precipitation. It is most likely around June 26, when it is observed during 35% of all days.

Moderate rain is the most severe precipitation observed during 24% of those days with precipitation. It is most likely around September 15, when it is observed during 33% of all days.

Moderate snow is the most severe precipitation observed during 23% of those days with precipitation. It is most likely around January 17, when it is observed during 35% of all days.

Light snow is the most severe precipitation observed during 21% of those days with precipitation. It is most likely around March 23, when it is observed during 28% 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 9 to September 6, there is a 65% 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 light rain (51% of days with precipitation have at worst light rain) and moderate rain (41%).

During the cold season, which lasts from November 13 to March 25, there is a 71% 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 (44% of days with precipitation have at worst moderate snow), light snow (35%), light rain (10%), and moderate rain (9%).

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 64% of days. The season in which it is relatively likely for snow to fall spans from October 14 to May 15.

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 50% (comfortable) to 96% (very humid) over the course of the year, rarely dropping below 31% (comfortable) and reaching as high as 100% (very humid).

The air is driest around May 31, at which time the relative humidity drops below 59% (mildly humid) three days out of four; it is most humid around September 6, exceeding 94% (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 11°F (dry) to 52°F (very comfortable) and is rarely below -5°F (dry) or above 57°F (comfortable).

The time of the year between July 10 and August 19 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 0 mph to 14 mph (calm to moderate breeze), rarely exceeding 24 mph (strong breeze).

The highest average wind speed of 8 mph (gentle breeze) occurs around January 28, at which time the average daily maximum wind speed is 14 mph (moderate breeze).

The lowest average wind speed of 6 mph (light breeze) occurs around September 3, at which time the average daily maximum wind speed is 10 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 is most often out of the south (13% of the time). The wind is least often out of the north east (1% of the time) and west (2% 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.
