I am visit taiwan coming 22-27 october how temperature & any raining seasons for this time.

Actually, it is still during the rainy season then, so it may rain. According to the weather reports in the past years and the personal exprerance, it would rain then, not frequently, but a little heavy. The average temperature is about 22-24 C. So short and long sleeved shirts and a light overcoat need to be prepared.
