Burnett Mary region sees spike in severe heat days

A COMPREHENSIVE climate guide has shown an increase in heat stress days for the Burnett Mary region over the past 30 years.

Findings in this report indicate the Burnett Mary region has seen a rise in days over 35°C, and more severe heat stress days for livestock.

In a collaborative effort by the Bureau of Meteorology, Farmlink and CSIRO, this localised climate guide has been created to aid farmers.

Through an in-depth analysis of climate data, the report endeavours to present historical and useful weather information from the last three decades.

The Burnett Mary region is one of dozens of regions attributed with guides, indicating a concerning rise in extreme heat events.

Using the Temperature Humidity Index (THI), it measures heat stress for animals and humans, with a THI of 80 and above classified as moderate to severe stress.

Gayndah experienced an average of 86 days per year with a THI of 80 and above between 1989-2018, eclipsing their previous average of 72 days between 1959-1988.

This rise was similar in the measuring of days of extreme heat, with Kingaroy experiencing an average of eight days per year over 35°C between 1989-2018.

Their average was half this between 1959-1988, only experiencing four days on average per year above 35°C.

Another unusual trend for the region showed a spike of six or more days in a row above 35°C in Kingaroy.

Records like this haven't been seen since 1957.

The primary aim of the report is to provide the agriculture industry with relevant information for decision making.

Annual rainfall, rainfall timing, and heavy rain events have also been measured over a 30 year period for regions across Australia.
