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 Shizukuishi is essentially constant during February, remaining around 0% throughout.

For reference, on August 6, the muggiest day of the year, there are muggy conditions 68% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

The topography within 2 miles of Shizukuishi contains significant variations in elevation, with a maximum elevation change of 535 feet and an average elevation above sea level of 682 feet. Within 10 miles contains significant variations in elevation (4,797 feet). Within 50 miles also contains extreme variations in elevation (6,594 feet).

The area within 2 miles of Shizukuishi is covered by trees (38%), cropland (33%), and water (14%), within 10 miles by trees (67%) and cropland (22%), and within 50 miles by trees (79%) and cropland (14%).

This report illustrates the typical weather in Shizukuishi, 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 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Shizukuishi.

For each station, the records are corrected for the elevation difference between that station and Shizukuishi 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 Shizukuishi is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Shizukuishi and a given station.

The stations contributing to this reconstruction are:

  • Akita Airport (RJSK, 45%, 41 mi, west, -318 ft elevation change)
  • Hachinohe Ab (RJSH, 23%, 65 mi, northeast, -479 ft elevation change)
  • Aomori Airport (RJSA, 19%, 74 mi, north, 33 ft elevation change)
  • Matsushima Ab (RJST, 14%, 90 mi, south, -623 ft elevation change)

To get a sense of how much these sources agree with each other, you can view a comparison of Shizukuishi 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.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . 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.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

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.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
