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.

Tennant Creek experiences significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 4.6 months, from November 14 to April 1, during which time the comfort level is muggy, oppressive, or miserable at least 12% of the time. The muggiest day of the year is February 10, with muggy conditions 46% of the time.

The least muggy day of the year is August 8, when muggy conditions are essentially unheard of.

Wind

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 Tennant Creek experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 7.6 months, from March 18 to November 5, with average wind speeds of more than 5.5 miles per hour. The windiest day of the year is April 30, with an average hourly wind speed of 6.1 miles per hour.

The calmer time of year lasts for 4.4 months, from November 5 to March 18. The calmest day of the year is December 5, with an average hourly wind speed of 5.0 miles per hour.

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 some seasonal variation over the course of the year.

The brighter period of the year lasts for 4.2 months, from September 27 to February 6, with an average daily incident shortwave energy per square meter above 7.0 kWh. The brightest day of the year is October 31, with an average of 7.6 kWh.

Data Sources

This report illustrates the typical weather in Tennant Creek, 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 is only a single weather station, Tennant Creek, in our network suitable to be used as a proxy for the historical temperature and dew point records of Tennant Creek.

At a distance of 2 kilometer from Tennant Creek, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

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

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , 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.
