A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Goondiwindi varies throughout the year.

The wetter season lasts 4.5 months, from October 18 to March 1, with a greater than 19% chance of a given day being a wet day. The chance of a wet day peaks at 28% on December 13.

The drier season lasts 7.5 months, from March 1 to October 18. The smallest chance of a wet day is 9% on August 13.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 28% on December 13.

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Goondiwindi experiences some seasonal variation in monthly rainfall.

Daylight saving time (DST) is not observed in Goondiwindi during 2017.

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.

Goondiwindi experiences some seasonal variation in the perceived humidity.

The muggier period of the year lasts for 3.9 months, from November 22 to March 20, during which time the comfort level is muggy, oppressive, or miserable at least 6% of the time. The muggiest day of the year is February 3, with muggy conditions 23% of the time.

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

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 Goondiwindi experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 6.4 months, from August 31 to March 13, with average wind speeds of more than 4.6 miles per hour. The windiest day of the year is November 26, with an average hourly wind speed of 5.3 miles per hour.

The calmer time of year lasts for 5.6 months, from March 13 to August 31. The calmest day of the year is April 28, with an average hourly wind speed of 4.0 miles per hour.

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 significant seasonal variation over the course of the year.

The brighter period of the year lasts for 3.9 months, from October 23 to February 19, with an average daily incident shortwave energy per square meter above 7.0 kWh. The brightest day of the year is December 28, with an average of 7.9 kWh.

The darker period of the year lasts for 3.0 months, from May 5 to August 4, with an average daily incident shortwave energy per square meter below 4.3 kWh. The darkest day of the year is June 16, with an average of 3.4 kWh.

Temperature and Dew Point

There is only a single weather station, Oakey Aerodrome, in our network suitable to be used as a proxy for the historical temperature and dew point records of Goondiwindi.

At a distance of 189 kilometers from Goondiwindi, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .

The weight assigned to the MERRA-2 value depends on the distance from Goondiwindi to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 44%, making the weight assigned to the weather station 56%.

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.
