Why is the temperature in Conghua, Guangzhou lower than that in Beijing, Shanghai and Chongqing?

I checked the meteorological observation data of yesterday and today.

Yesterday, the lowest temperature in Beijing was 4.4 degrees, 0.7 degrees from Conghua;

The lowest temperature in Beijing today is 0.9 degrees, and the lowest temperature in Conghua is 1.8 degrees.

Shanghai and Chongqing are taller than Beijing.

Reason: Yesterday, Beijing was outside the cold air front, and the temperature rose due to the southerly airflow.

Conghua is affected by cold air and radiation cooling, and the temperature is low.

This phenomenon is common in China, but with the acceleration of global warming, this phenomenon will be more.
