It generally rains around 374 mm (about 14 inches).
The average temperature in Kathmandu in July is 24°C (75°F), reaching highs of 27°C (81°F), and dropping to lows of 21°C (70°F).
If you are travelling to Kathmandu during this period, be sure to carry a decent raincoat and mosquito repellent, as the number of mosquitoes increases significantly.
It is also advisable to carry all the skin care products from home itself, as Nepal is known for providing duplicate products.
Make sure you are adequately prepared with skin products that suit your skin from home, so as to protect yourself and avoid any adverse reactions from products that you are not familiar with.
July is the most humid month as well.
This makes the climate very warm and muggy.
The positive side of all this rain is that it makes the valley very green and lush.
The possibility of rain in July is for 21 days throughout the month.
July is also very quiet in terms of tourists as the main attractions i.e. the mountains, are covered with clouds throughout the entire month.
