Is it worth visiting Yunnan in july when it rains the most? Or does it usually rains all day?

Take Kunming as an example, the temperature may range from 60 F to 75 F in July. And there will have mainly cloudy and sunny days. Several rainy days usually occurs in the end of the month. But it's still advised to keep close attention to the weather forecast before going there. If it have heavy rains, you won't to visit mountain area at that day.
