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 17.8 °C. In New Zealand, February is the warmest month, with 22.1 °C. There, it is coolest in July with an average of 12.6 °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 18.2 °C. In New Zealand, it is coolest at night in July at 4.7 °C and warmest in February at 13.3 °C. This corresponds to a cooling of 10.3 to 12.7 °C in Australia and 7.8 to 8.9 °C in New Zealand.

Humidity

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

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.

Rain days per month

By definition, a rain 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 New Zealand, it rains most often in July with 13.0 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 New Zealand, the average amount of precipitation ranges from 2.6 liters per day in January to 4.0 in June. However, these are average values. If you consider that there are only 12.6 rainy days in New Zealand in June, each of them accounts for about 9.6 liters.

Sunshine hours per day

With 2,884 hours of sunshine per year, Australia is in the lead. The most hours of sunshine (9.1 per day) are in January. New Zealand falls into second place with only 2,081 hours. There the sun is visible in June for only 3.7 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 New Zealand, it is 9.4 hours in June and 15.1 in December.
