Rainfall

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

The average sliding 31-day rainfall during the summer in Hatteng is increasing, starting the season at 1.9 inches, when it rarely exceeds 3.2 inches or falls below 0.8 inches, and ending the season at 2.7 inches, when it rarely exceeds 4.7 inches or falls below 1.2 inches.

The highest average 31-day accumulation is 3.2 inches on July 17.

Due to its extreme latitude, Hatteng 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 in Hatteng during 2024, the Sun is continuously above the horizon for 2.1 months, rising at 12:54 AM on May 19, and not setting again until 12:27 AM on July 24. As such, summer begins in polar day, which ends before summer is over.

The shortest day of the summer is August 31, with 15 hours, 24 minutes of daylight.

The earliest sunrise of the summer in Hatteng is 1:06 AM on July 24 and the latest sunrise is 3 hours, 51 minutes later at 4:57 AM on August 31.

The latest sunset is 12:27 AM on July 23 and the earliest sunset is 4 hours, 7 minutes earlier at 8:20 PM on August 31.

Daylight saving time is observed in Hatteng during 2024, but it neither starts nor ends during the summer, so the entire season 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 the summer of 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 in Hatteng is essentially constant during the summer, 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 in Hatteng is essentially constant during the summer, remaining within 0.4 miles per hour of 6.0 miles per hour throughout.

For reference, on January 23, the windiest day of the year, the daily average wind speed is 10.0 miles per hour, while on August 11, the calmest day of the year, the daily average wind speed is 5.7 miles per hour.

The lowest daily average wind speed during the summer is 5.7 miles per hour on August 11.

The wind direction in Hatteng during the summer is predominantly out of the west from June 1 to August 12 and the south from August 12 to August 31.

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 in Hatteng are increasing during the summer, increasing by 321°F, from 12°F to 333°F, over the course of the season.

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.
