Daytime temperatures will drop by about 3 to 6 degrees compared to the previous day, remaining similar to the average (24~29 degrees Celsius), but many places, especially in the central regions, will rise to around 30 degrees.

The morning low temperature will be between 20 and 23 degrees Celsius, and the daytime high temperature will be around 24 to 30 degrees Celsius.
