Parts of New South Wales and the ACT shivered through their coldest nights since September. Clear skies combined with light winds overnight causing the mercury to plummet. The ACT and southern parts of NSW were the coldest, as a high pressure system sat over the region in the early hours of this morning.

Bega and Albury in NSW both saw their chilliest mornings since September, reaching one and two degrees respectively. Canberra and Tuggeranong in the ACT plummeted to minus two degrees, also their coldest nights since spring.

Most weather-minded people know that Death Valley, California and Vostok, Antarctica have measured the highest and lowest extreme temperatures on earth but what about the warmest and coldest inhabited places so far as average annual temperatures are concerned? Ace temperature detective Maximiliano Herrera has just finished researching this. Here are his findings.

Hottest inhabited place in the world

Although it has been widely reported that Dallol in the Danakil Depression of Ethiopia has the highest average annual temperature on earth with a figure of 34.5°C (94.1°F) the figure was derived from only seven years of data (1960-1966) by a mining company that was prospecting in the depression during those years. Actually, there were many missing months of record during those seven years and the total number of months with complete data was just 58. The location has never been permanently inhabited and there has been little or no weather data for the site since the 1960s. Nevertheless, from a climatological viewpoint the Danakil Depression probably is the hottest place on earth (in terms of average annual temperature). But for inhabited locations it would appear that Mecca (or Makah), Saudi Arabia is the warmest inhabited location on earth. Its average annual temperature is 30.7°C (87.3°F).

May has kicked off with unusually warm weather in southwestern parts of Western Australia, after many parts had record breaking heat during April. Perth had its hottest April in 116 years of records, with an average maximum of 28.5 degrees. This has only happened three times since records began. In terms of minima it was the capital's second hottest April on record, second only to April 1962.

In the Great Southern District Narrogin, Brookton, Corrigin and Pingelly all broke records for minimum and maximum temperatures in April. Elsewhere, Esperance hasn't had a hotter April in at least 20 years, while for Medina you need to go back at least 26 years. It has been nearly a decade since Kalgoorlie had such hot April days.

Parts of Tasmania have just been hit by their first severe frost of the season with temperatures plummeting as low as minus five degrees, 10 below average. For some it was the most severe April frost in four years.

The thickest frost overnight and early this morning was in eastern, central and northern parts, where many centres recorded their lowest temperature since last September. Fingal, Ross and Cressy all had their coldest night since last winter with a minimum temperature of -4.6 and minus four degrees respectively, 10 degrees below the April average. This was also the coldest April night in four years for Fingal and Cressy.

Many inland parts of NSW are facing their driest April in more than a decade, with some towns having seen no rain at all this month. A series of broad, slow-moving high pressure systems have been responsible for predominantly clear skies and dry conditions, while preventing any strong rain-bearing fronts from reaching inland areas.

With only one day to go, much of the Upper Western is set to end the month with zero rainfall. This includes Brewarrina, Cobar and Lightning Ridge. It has been five years since Brewarrina and Lightning Ridge saw a dry April, and at least ten years for Cobar.
