The rainy season lasts up to the end of September, meaning that August is the second wettest month of the year.
The weather throughout this month remains cloudy so it is not the ideal time of the year to travel to Kathmandu.
The weather will also affect your ability to hike in the mountains and explore the area.
During August it generally rains around 345 mm (about 13 inches).
The average daytime temperatures are around 28°C (82°F) so the climate is hot and wet, meaning high humidity. If a suana-like climate is what you enjoy, this is the time to visit Kathmandu!
Moreover, adding to the discomfort are the mosquitoes, which increase in number significantly due to the rain.
Make sure you pack a decent mosquito repellant if you do visit the area in August, and do not rely on purchasing products whilst you are out there, as Nepal is known for producing duplicate products and they may not be safe or protect you.
You also would not wish to have an adverse reaction to any new products whilst you are out there, which may affect your holiday, so be sure to use products that you are familiar with.
Throughout the month, Kathmandu is fairly quiet due to the low visibility.
The mountains remain covered by clouds throughout the month. Trekking is impossible during these months as it pours heavily and the rain is relentless.
Sometimes the rain doesn't stop even after 6 to 8 days; it keeps pouring down at a constant rate, which makes all the outdoor activities inconvenient.
