What temperature is not suitable for composting?
When moisture content is high, temperatures near the surface will be higher. Above 160°F, compost is too hot. Few thermophilic organisms are able to get much done when their environment is too hot. If left above 160°F, bacteria will cease active decomposition, which in turn will render the pile inert.

24 to 36 hoursIf the pile is built correctly, it will heat up within 24 to 36 hours to the ideal temperature of 141°F to 155°F (weed seeds and disease pathogens die at these temperatures) and will maintain its temperature for several days to a week or longer. Use a compost thermometer to monitor the temperature.

How does temperature affect compost?
Temperatures within compost piles affect microbial growth and activities, and hence the rate at which the raw materials decompose. Higher temperatures result in faster breakdown of organic materials, destroy weed seeds, and kill pathogens. However, excessively high temperatures (>160˚F) can inhibit microbial activity.

160 degrees FahrenheitThe optimum temperature for compost to process is 160 degrees Fahrenheit (71 C). In sunny, hot climates where the pile hasn't been turned recently, even higher temperatures can occur.
How do I know the temperature of my compost?
To measure compost temperatures, you will need a long-probe thermometer (generally 4 feet in length) to obtain readings from the core of the windrow or static pile. It is important to establish consistent technique and locations for taking temperature measurements from an active windrow or static pile.
Why is the temperature of the compost pile higher than the ambient air temperature?
Most of the temperature rise within the composting material is a result of the activity of the microbes in the bin. As the microorganisms work to decompose the compost, their metabolic activity generates heat, which raises the temperature of the composting material.
