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 Adelaide is essentially constant during the winter, remaining around 0% throughout.

For reference, on February 6, the muggiest day of the year, there are muggy conditions 2% of the time, while on May 7, 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 Adelaide is gradually increasing during the winter, increasing from 9.7 miles per hour to 10.3 miles per hour over the course of the season.

For reference, on January 17, the windiest day of the year, the daily average wind speed is 11.9 miles per hour, while on May 18, the calmest day of the year, the daily average wind speed is 9.4 miles per hour.

The highest daily average wind speed during the winter is 10.7 miles per hour on July 1.

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).

Temperatures in Adelaide are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

This report illustrates the typical weather in Adelaide, 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 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Adelaide.

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

The stations contributing to this reconstruction are:

  • Adelaide Airport (YPAD, 42%, 4 mi, west, -174 ft elevation change)
  • Adelaide (APAD, 42%, 4 mi, west, -174 ft elevation change)
  • Parafield Airport (YPPF, 16%, 10 mi, north, -138 ft elevation change)

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