What temperature is considered heat stress in Australia?

Heat stress conditions typically begin when temperatures exceed 35u00b0C, particularly when combined with high humidity. In Dayboro, Queensland, temperatures can reach 38u00b0C or higher during summer heatwaves. The combination of high temperature and high humidity makes it harder for both humans and animals to cool down through sweating or panting, increasing the risk of heat-related illness.

How does high humidity make heat stress worse?

High humidity reduces the body's ability to cool itself through evaporation. When the air is already saturated with moisture, sweat cannot evaporate efficiently from skin, and animals cannot cool down through panting. This means the effective temperature feels much higher than the actual reading. In subtropical areas like Dayboro, Queensland, summer days often combine temperatures above 35u00b0C with high humidity, creating dangerous heat stress conditions for people, livestock, and pets.

Can a dropping barometer in the morning mean thunderstorms?

Yes, a falling barometric pressure during morning hours can indicate approaching storms or a change in weather conditions. Normally, barometric pressure rises in the morning as part of the daily pressure cycle. When it drops instead , particularly on a hot, humid day , it can signal that thunderstorms are developing. In South East Queensland, summer heat combined with falling pressure often precedes afternoon or evening thunderstorm activity.

How do you protect livestock from heat stress in Queensland?

To protect livestock during extreme heat in Queensland, ensure animals have access to shade and plenty of fresh, cool water at all times. Avoid moving or handling stock during the hottest part of the day. Provide additional water troughs and check them frequently, as consumption increases dramatically above 35u00b0C. Watch for signs of heat stress in cattle including heavy panting, drooling, and reduced movement. On days forecast to exceed 38u00b0C, consider using sprinklers or misters in holding yards.

What is a safe barometric pressure reading in Australia?

Normal barometric pressure in Australia sits around 1013 hPa at sea level. Readings above 1010 hPa are generally considered stable and fair-weather conditions. A reading of 1005 hPa, while still within a safe range, is on the lower side and worth monitoring , particularly if it is actively dropping. Rapidly falling pressure (more than 2-3 hPa per hour) can indicate an approaching storm front or severe weather, which is especially relevant during Queensland's summer storm season.

22nd of January 2024 Heat Stress Warning

Dayboro’s weather station forecast 38°C with rising humidity and a dropping barometer on 22 January 2024, raising heat stress concerns for livestock and pets in the region.

The weather station shows possible 38C today, as I am writing this the temperature is already up to 32C and climbing about 2C per hour.

The interesting thing is that the Barometer is dropping at the moment, something it normally does not do in the morning. It is still at 1005hPa so that is all good, but something to keep an eye on as it might spell thunderstorms.

Anyway the humidity is high, temperature is high the combination that makes it harder for animals to get cooled down.

Soil moisture now reads the root zone, with a deep reserve line

The soil moisture figure on dayboro.au now comes from the probe at 20 cm, where seedlings and veggies actually drink. The 35 cm probe is still there, reported as the deep reserve.

From lyndhurst-hill.info to dayboro.localbuddy.au: what changed, and what never will

There is a new home for the Dayboro community feed at dayboro.localbuddy.au, and that has caused some confusion. The short version: nothing is going away. The weather stays on dayboro.au, the events stay on dayboro.au, and the Dayboro Lions Business Directory stays the authority on local businesses, hosted free, as it has been since 2017. This is the long version of how we got here.

We Hit 36.9 On Sunday. I Spent Two Days Trying To Prove It Wrong

The station read 36.9 degrees on Sunday afternoon, the hottest September figure it has ever logged. I did not believe it, so I went looking for the fault. A second weather station in Dayboro read exactly the same number, and what I found instead was a real problem in my own record that runs the other way.
