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 Hochdonn is essentially constant during the summer, remaining within 1% of 1% throughout.

The highest chance of a muggy day during the summer is 1% on August 10.

For reference, on August 10, the muggiest day of the year, there are muggy conditions 1% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

This report illustrates the typical weather in Hochdonn, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Hochdonn.

For each station, the records are corrected for the elevation difference between that station and Hochdonn according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Hochdonn is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Hochdonn and a given station.

The stations contributing to this reconstruction are:

  • Itzehoe (ETHI, 60%, 12 mi, east, 82 ft elevation change)
  • Hohn (ETNH, 25%, 22 mi, northeast, 33 ft elevation change)
  • Sea-Airport Cuxhaven/Nordholz (ETMN, 15%, 31 mi, southwest, 69 ft elevation change)

To get a sense of how much these sources agree with each other, you can view a comparison of Hochdonn and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , by Jean Meeus.

This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.
