It's been a balmy month in northern Queensland, with Townsville on track to register its warmest July on record based on maximum temperatures.

July is typically Townsville's coldest month of the year:

• The long-term average maximum temperature for July is 25.2ºC
• The average minimum temperature for the month is 13.7ºC

But this year, July has been warmer than June and based on daytime temperatures alone, Townsville is also having its warmest July on record.

As of 9am on Wednesday, Townsville Airport's running monthly average temperatures were:

• Maximum: 27.0ºC
• Minimum: 16.3ºC
• Mean: 21.7C

This is currently the highest July monthly maximum temperature on record, beating 26.8ºC from 2003, with data available back to 1941.

With the final four days of the month all forecast to reach 27-28ºC, the current record warm average maximum temperature could edge even higher by the end of July.

Nights have also been warm, but not record-breaking. Townsville's average minimum temperature so far this month is currently the warmest since 2016, making the July running mean temperature Townsville's highest since 2010.

This month's unusually warm temperatures have also been accompanied by plenty of dry days. As of 9am Wednesday, Townsville Airport had only registered 5.4mm of rain, its wettest July in four years.
