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 Blue Earth is essentially constant during October, remaining within 1% of 1% throughout.

For reference, on July 20, the muggiest day of the year, there are muggy conditions 39% of the time, while on November 2, the least muggy day of the year, there are muggy conditions 0% of the time.

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 Blue Earth is gradually increasing during October, increasing from 11.2 miles per hour to 11.7 miles per hour over the course of the month.

For reference, on April 8, the windiest day of the year, the daily average wind speed is 13.4 miles per hour, while on August 2, the calmest day of the year, the daily average wind speed is 8.5 miles per hour.

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).

The growing season in Blue Earth typically lasts for 5.5 months (166 days), from around April 22 to around October 5, rarely starting before April 3 or after May 11, and rarely ending before September 17 or after October 24.

During October in Blue Earth, the chance that a given day is within the growing season is very rapidly decreasing falling from 60% to 4% over the course of the month.

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 Blue Earth are gradually increasing during October, increasing by 130°F, from 2,714°F to 2,844°F, over the course of the month.

For the purposes of this report, the geographical coordinates of Blue Earth are 43.637 deg latitude, -94.102 deg longitude, and 1,086 ft elevation.

The topography within 2 miles of Blue Earth is essentially flat, with a maximum elevation change of 69 feet and an average elevation above sea level of 1,075 feet. Within 10 miles is essentially flat (161 feet). Within 50 miles contains only modest variations in elevation (827 feet).

The area within 2 miles of Blue Earth is covered by cropland (87%), within 10 miles by cropland (99%), and within 50 miles by cropland (96%).

This report illustrates the typical weather in Blue Earth, 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 6 weather stations near enough to contribute to our estimation of the temperature and dew point in Blue Earth.

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

The stations contributing to this reconstruction are:

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

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series.
