The weather in Wuhan at the end of March

On March 20th, the historical average temperature in Wuhan was 8- 15 degrees, the extreme maximum temperature was 1990 26 degrees, and the extreme minimum temperature was 1964 0 degrees. If this once-in-a-century extreme temperature does not appear, it usually fluctuates around 8- 15 degrees, so I still want a thin sweater, like I am afraid of cold.
