Hi, I intend to travel to Taiwan from 22 June to 3 July. Can you kindly advise on the weather?

The temperature may range from 25 C to 30 C during that period. There will have frequent heavy rainy days. To be honest, it won't be a good time for sightseeing. The rain will influence your sightseeing a lot. You can change the travel plan and visit Tawan from October to May next year.
