According to Bureau of Meteorology statistics, Glen Innes recorded an average maximum temperature of 15.3 degrees for July, 3 degrees above the month average of 12.6.

It's the warmest average since 1993, when the station measured 15.4 degrees as the average maximum.

That's despite Glen Innes posting its coldest July morning in 25 years in a week when the town was for three days the coldest place in Australia

The reading of minus 12.3 was also the coldest temperature measurement anywhere in the country for 2019.

The Glen Innes airport weather station also set new records, recording its highest average maximum temperatures since 2002.

Both weather stations measured "very low" rainfall in July with levels sitting at about one tenth average for both. Glen Innes has received less than half its average rainfall for 2019.

Tenterfield, a town desperately staving off level five water restrictions, received its lowest rainfall since 1970. Armidale has set a new record; in 2019 the town recorded its lowest rainfall ever for the month of July.

Inverell, Moree, Armidale, Guyra, Moree and Inverell have all also experienced their warmest month of July in decades, with Inverell setting its highest average minimum temperature ever.

Glen Innes is on level 3 water restrictions as of August 1. The current drought has been described by BOM climatologist David Jones as the worst on record, comparing it with million year-old records.

Mayor Carol Sparks said the water crisis was a result of climate change. Council decided to jump a water level early barely a day after going to level 2.

Nationally, July was the fourth-warmest on record for Australia.

The unseasonably warm winter weather looks set to continue in August, with tops of 16 and 17 degrees forecast until Friday.
