Rainfall

To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.

The average sliding 31-day rainfall during June at Danmarkshavn is gradually increasing, starting the month at 0.1 inches, when it rarely exceeds 0.3 inches or falls below -0.0 inches, and ending the month at 0.5 inches, when it rarely exceeds 1.2 inches.

Snowfall

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day.

The average sliding 31-day snowfall during June at Danmarkshavn is decreasing, starting the month at 2.3 inches, when it rarely exceeds 6.7 inches or falls below -0.0 inches, and ending the month at 0.4 inches, when it rarely exceeds 1.1 inches or falls below -0.0 inches.

Due to its extreme latitude, Danmarkshavn experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. 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 the summer at Danmarkshavn during 2024, the Sun is continuously above the horizon for 3.9 months, rising at 12:38 AM on April 22, and not setting again until 11:56 PM on August 19. As such, the sun is continuously above the horizon for the entire month of June.

Daylight saving time is observed at Danmarkshavn during 2024, but it neither starts nor ends during June, so the entire month is in standard time.

The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation.

The figure below presents a compact representation of key lunar data for June 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy at Danmarkshavn is essentially constant during June, remaining around 0% throughout.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed at Danmarkshavn is gradually decreasing during June, decreasing from 8.1 miles per hour to 7.6 miles per hour over the course of the month.

For reference, on January 5, the windiest day of the year, the daily average wind speed is 16.3 miles per hour, while on June 21, the calmest day of the year, the daily average wind speed is 7.5 miles per hour.

The lowest daily average wind speed during June is 7.5 miles per hour on June 21.

The hourly average wind direction at Danmarkshavn throughout June is predominantly from the north, with a peak proportion of 50% on June 1.

Danmarkshavn is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average surface water temperature at Danmarkshavn is essentially constant during June, remaining within 1°F of 30°F throughout.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).

Temperatures at Danmarkshavn are sufficiently cold year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.

The average accumulated growing degree days at Danmarkshavn are essentially constant during June, remaining around 0°F throughout.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy at Danmarkshavn is essentially constant during June, remaining within 0.2 kWh of 7.3 kWh throughout.

The highest average daily incident shortwave solar energy during June is 7.6 kWh on June 16.
