Tips for the Summer
An El Niño was officially announced by the Bureau of Meteorology on 19 September 2023 for the first time in eight years. BOM also announced the development of a lesser known, but also significant, climate driver known as a “positive” Indian Ocean Dipole (IOD). This has received less of the media attention but will be an important driver for the coming few months.
We have all heard what El Niño conditions hold for us (hot, dry, less cyclones) but what about the combined effect of an El Niño and Positive IOD? The Bureau states that
“When a positive IOD and El Niño occur together, their drying effect is typically stronger and more widespread across Australia.”
We have gone back over the records and identified when these conditions have previously occurred over the last 30 years. We found that similar conditions occurred in the early 90s, 1997 and spring of 2014.
The spring of 2014 was the hottest on record and the summer saw many severe heat waves.
The charts above show the rain and temperature for October – December for the historical periods with El Niño and Positive IOD.
The BOM have issued a heatwave warning but I have not received any Kite alerts! We discuss how this information is presented on Kite.
As you head into summer it is good to remind yourself of the types of weather events that can cause heat load problems. Read more.
With the peak storm period on us, it is good to reassess the issues with wet pens.
Humidity in the pens can be significantly higher than outside the pens, so your weather station may not indicate the true heat load exposure of your animals, nor will the forecast. Read more about what you can do to manage this risk.
