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 Broken Hill is gradually decreasing during the fall, falling from 2% to 0% over the course of the season.

For reference, on January 24, the muggiest day of the year, there are muggy conditions 4% of the time, while on May 8, 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 Broken Hill is decreasing during the fall, decreasing from 10.5 miles per hour to 8.8 miles per hour over the course of the season.

For reference, on December 13, the windiest day of the year, the daily average wind speed is 11.5 miles per hour, while on May 19, the calmest day of the year, the daily average wind speed is 8.6 miles per hour.

The lowest daily average wind speed during the fall is 8.6 miles per hour on May 19.

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 Broken Hill typically lasts for 11 months (345 days), from around July 22 to around July 3, rarely starting after August 21, or ending before June 10.

The fall in Broken Hill is very likely fully within the growing season, with the chance that a given day is in the growing season gradually decreasing from 100% to 96% over the course of the 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 50°F and a cap of 86°F.

The average accumulated growing degree days in Broken Hill are very rapidly increasing during the fall, increasing by 1,264°F, from 3,964°F to 5,227°F, over the course of the season.

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

Broken Hill is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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.

The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Broken Hill, according to the International Standard Atmosphere .

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.

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.
