Humidity
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.
Mitchell experiences significant seasonal variation in the perceived humidity.
The muggier period of the year lasts for 3.1 months, from 8 June to 12 September, during which time the comfort level is muggy, oppressive, or miserable at least 10% of the time. The month with the most muggy days in Mitchell is July, with 11.1 days that are muggy or worse.
The least muggy day of the year is 20 February, when muggy conditions are essentially unheard of.

Best Time of Year to Visit
To characterize how pleasant the weather is in Mitchell throughout the year, we compute two travel scores.
The tourism score favors clear, rainless days with perceived temperatures between 18°C and 27°C. Based on this score, the best time of year to visit Mitchell for general outdoor tourist activities is from mid June to early September, with a peak score in the first week of August.
Tourism Score in Mitchell
The tourism score (filled area), and its constituents: the temperature score (red line), the cloud cover score (blue line), and the precipitation score (green line).
The beach/pool score favors clear, rainless days with perceived temperatures between 24°C and 32°C. Based on this score, the best time of year to visit Mitchell for hot-weather activities is from late June to mid August, with a peak score in the third week of July.
Beach/Pool Score in Mitchell
The beach/pool score (filled area), and its constituents: the temperature score (red line), the cloud cover score (blue line), and the precipitation score (green line).
Methodology
For each hour between 08:00 and 21:00 of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.
Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 1 millimetre of precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 10°C, rising linearly to 9 for 18°C, to 10 for 24°C, falling linearly to 9 for 27°C, and to 1 for 32°C or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 18°C, rising linearly to 9 for 24°C, to 10 for 28°C, falling linearly to 9 for 32°C, and to 1 for 38°C or hotter.
Growing Season
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 (≥ 0°C) in the year (the calendar year in the Northern Hemisphere, or from 1 July until 30 June in the Southern Hemisphere).
The growing season in Mitchell typically lasts for 5.3 months (161 days), from around 26 April to around 5 October, rarely starting before 6 April or after 18 May, and rarely ending before 16 September or after 24 October.

The percentage of time spent in various temperature bands. The black line is the percentage chance that a given day is within the growing season.
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 10°C and a cap of 30°C.
Based on growing degree days alone, the first spring blooms in Mitchell should appear around 15 April, only rarely appearing before 1 April or after 3 May.
Solar Energy
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 experiences extreme seasonal variation over the course of the year.

Data Sources
This report illustrates the typical weather in Mitchell, based on a statistical analysis of historical hourly weather reports and model reconstructions from 1 January 1980 to 31 December 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Mitchell.
For each station, the records are corrected for the elevation difference between that station and Mitchell 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 Mitchell is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Mitchell and a given station.
The stations contributing to this reconstruction are:
- Mitchell Municipal Airport (KMHE, 97%, 7 km, north, -2 m elevation change)
- Chan Gurney Municipal Airport (KYKN, 1.7%, 107 km, southeast, -41 m elevation change)
- The O'Neill Municipal Airport (KONL, 1.0%, 148 km, south, 221 m elevation change)

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