A weather station in Oman may have challenged the world record for the highest 24-hour minimum temperature earlier this week.

The coastal town of Qurayyat, located to the east of Oman's capital city Muscat, registered a minimum temperature of 42.6 degrees Celsius on Tuesday.

Some weather record experts suggest that this could be the highest 24-hour minimum temperature on record anywhere in the world. This means the lowest temperature recorded at that site during the 24 hour period from midnight to midnight local time.

This week's potentially record-breaking heat comes one year after Oman's Khasab Airport made headlines for registering an overnight minimum temperature of 44.2 degrees Celsius during June 2017. This value is thought to have been an overnight minimum temperature world record by some experts.

The trouble is, there is no international authority on high minimum temperature records. The World Meteorological Organisation (WMO) maintains a Climate and Weather Extremes Archive, which lists the highest and lowest temperatures recorded reliably anywhere in the world.

The WMO's archive does not, however, include information on the highest minimum or lowest maximum temperature world records, so they cannot confirm whether Qurayyat or Khasab have actually set new world records.

The data has been logged though, and the WMO may include these metrics in their Climate and Weather Extremes Archive in the future.

According to the Bureau of Meteorology, Australia's highest 24-hour minimum temperature was 35.5 degrees at Wittenoom in Western Australia on 21st January in 2003 and Arkaroola in South Australia on 24th January, 1982.

Not far off the record, a couple of weather stations in Adelaide registered a minimum temperature of 35.2 degrees on 24th January 1982.

It should be pointed out that Australia's 24 hour minimum temperatures are taken between 9am and 9am local time.
