Daily maximum temperatures
The highest daytime temperatures in Australia are reached in January with an average of 30.3 °C. The coldest month, on the other hand, is July, with an average of just 17.9 °C. In India, May is the warmest month, with 36.6 °C. There, it is coolest in January with an average of 26.2 °C.
Night time lows
At night, it cools down to varying degrees depending on the country and altitude. In Australia, temperatures drop as low as 7.0 °C in July. The warmest nights are in January at 18.1 °C. In India, it is coolest at night in January at 13.7 °C and warmest in June at 25.9 °C. This corresponds to a cooling of 10.4 to 12.7 °C in Australia and 6.6 to 13.1 °C in India.
The humidity of the air depends to a large extent on the air temperature. The warmer the air, the more water it can absorb. At a temperature of 25°C it is 23 grams per cubic meter, at 30 degrees it is already 26 grams. Therefore, the air humidity is given as a relative value to the temperature-dependent maximum amount. It becomes unpleasant when high humidity is combined with high temperatures.
Humidex is an approximate, sensed temperature calculated on the basis of air temperature, dew point and humidity. It was developed in 1965 by the Canadian meteorologists J. M. Masterton and F. A. Richardson. Since the wind speed is ignored here, it is not very meaningful in areas below approx. 15°C. Above that, it is more reliable, since at higher temperatures humidity plays a greater role than wind.
Rainy days per month
By definition, a rainy day is a day on which at least 0.1 liters of precipitation per m² fall. This corresponds to a 1 square meter puddle in which the water stands 0.1 mm high — insofar as the water does not seep away or evaporate. So it does not have to rain all day long. July brings the most rainy days (6.7) in Australia. With an average of only 5.2 days, April is the friendliest. In India, it rains most often in July with 17.8 days.
Precipitation amount per day
Depending on the season and the location of a country, the wind brings a varying amount of water with it. As a rule, the water evaporating in the oceans is absorbed and then transported inland. The greatest amount of rain (hail or dew are also forms of precipitation) in Australia occurs in February, when about 3.0 liters per square meter fall per day. In India, the average amount of precipitation ranges from 0.6 liters per day in February to 10.8 in July. However, these are average values. If you consider that there are only 17.8 rainy days in India in July, each of them accounts for about 18.1 liters.
Sunshine hours per day
With 2,920 hours of sunshine per year, Australia is in the lead. The most hours of sunshine (9.1 per day) are in January. India falls into second place with only 2,263 hours. There the sun is visible in July for only 3.6 hours per day, so not hidden behind clouds.
Hours of daylight
The length of a day varies throughout the year and depends on the distance from the equator. In June, the day in Australia is only 10.5 hours long. In December, on the other hand, it is 13.8 hours. In India, it is 10.9 hours in December and 13.4 in June.
