What's the temperature in southern Iraq? When is it cooler?

Southern Iraq is the hottest place in Iraq. There is no rain in the dry season from April to September (of course, there are occasional exceptions), and the average temperature is between 40 and 55 degrees (regardless of the weather forecast, the actual temperature is higher than the weather forecast). The rainy season from 10 to March next year is very cool, and the temperature is between 10- 40, which is a bit like the temperature difference between day and night in northern China. It is cool below 40 degrees in Iraq.
