Producers in the state's north west could experience more than 40 additional days above 35C by the year 2070 if future climate predictions remain unchanged.
That was the harsh but honest picture that was painted to those at the North West Beef Producers Forum and highlighted the need for better mindfulness of production systems.
NSW DPI research leader Dr Warwick Badgery was tasked with informing producers about the likelihood of 2019 weather conditions, the hottest year on record in Australia, being replicated in the future.
He warned that extreme events would increase in frequency and if current climate models continued on their current path maximum temperatures would rise by 0.7C by 2030 and by 2.1C by 2070.
By 2050 Quirindi could experience temperatures 1.9C hotter with no change in the frequency of rainfall.
This could result in pasture production forecasts falling by 14 per cent in the year 2070 which would render current systems 48 per cent less profitable by the same year.
But not all hope was lost.
Dr Badgery encouraged producers to increase their soil fertility, shift joining times if needed or provide adequate shade and look to barrel or snail medic as better adapted annual legumes.
"One of the key things is if we don't change the system and we run them as we currently are there is going to be a substantial impact on profit," he said.
"The heat will occur more often but the rainfall we are unsure of.
"We can effectively manage these conditions by understanding our environment and looking at the adaptation needed from a reference site is a good way to visual what changes are needed by making strategic changes.
"Understand what works now and what is likely to work in the future."
