Where should you go in Nepal in september when it comes to the weather?
Remember:
The climate in Nepal in september ranges from good to very bad depending on the region and city.
September is not the best month to go to in Nepal. The weather in Pokhara, Rudrapur and Nepalganj is quite correct. The sun is not there all the time and you might make you wet by rain frequently. Nevertheless, if you don't plan a beach and sun trip but rather visiting museums, this climate may suit. In addition, there are surely fewer tourists during this period.
It's much worse in Royal Chitwan National Park, Patan, Everest, Lukla and Kathmandu and surrounding areas where the climate is very bad. We really do not recommend you to travel to these areas this month.
