Good to Know
- The problem is at its worst between January and May, and again in November and December. August is historically the cleanest month, when monsoon rains and winds clear the air.
- Kathmandu is more uncomfortable than comfortable, louder than it is quiet, dirtier than it is clean, and more chaotic than most cities. Expect this as reality, not an exaggeration.
- WiFi is available in hotels, cafes, and restaurants in cities like Kathmandu and Pokhara, but speeds vary (5-20 Mbps). Confirm connectivity quality before committing to accommodation or coworking for time-sensitive work.
- Water quality remains inconsistent despite treatment. Use bottled or purified water for drinking and consider water purification tablets even for reputable establishments.
- During rainy season, unpaved roads and lack of sidewalks make walking difficult. Plan mobility accordingly if visiting during monsoon months.
- Despite infrastructure challenges, power outages have become less frequent than in previous years. Check current status with local contacts upon arrival.
Water Quality
- Drinking Water Safety
- Tap water in Kathmandu, Nepal, is generally not safe to drink without treatment. Contamination from sewage and industrial waste is common.
- Bacterial Contamination
- Drinking water used by Kathmandu and Lalitpur metropolitan city residents for drinking has been found contaminated with deadly microbes. According to officials at the Lalitpur Metropolitan City, 180 of 540 water samples collected from wards 7, 8, 9, 15, and 17 of the metropolis were found contaminated with faecal coliform. Similarly, of 506 samples of drinking water collected from wards 11, 12, and 13 of Kathmandu Metropolitan City, 98 were contaminated with faecal coliform.
- Treatment Recommendation
- Boiling, filtering, or using UV purification is recommended before consumption to avoid waterborne diseases. Many locals rely on bottled or treated water.
Safety Considerations
- General Assessment
- While locals are generally helpful and friendly, safety and comfort levels vary—especially for women—and care is needed in certain areas at night.
Infrastructure Challenges
- Power Supply
- Kathmandu Valley faces frequent power outages due to tripping even when there is enough power in the grid. Power cuts largely being a thing of the past with the current government providing some stability.
- General Status
- Infrastructure challenges remain; roads can be poor, power outages still occur occasionally, and water quality is unreliable.
- Road Quality And Walkability
- The city is not very walkable, particularly in rainy weather, where dirt roads and lack of sidewalks make mobility difficult.
Internet And Connectivity
- Reliability
- Although fiber internet is available in some places, frequent lag and downtimes hinder consistent connectivity, which is essential for remote workers.
- Hotel Wi-Fi Speeds
- Generally speaking accommodation Wi-Fi is around the 512kb - 1mb. In recent years guesthouse Wi-Fi has increased, but the networks have failed to keep up with the demand which results in slow speeds.
- Wi-Fi Availability
- Public WiFi is available in airports, hotels, cafes, restaurants, guesthouses, coworking venues, and tourism-focused businesses. While convenient for occasional browsing, speed and reliability can vary significantly depending on location, signal strength, and shared network usage.
Cleanliness And Sanitation
- Stray Animals
- Rivers are polluted, green spaces are sparse, and stray dogs are a common sight.
- General Conditions
- Air pollution is a major issue, especially during certain seasons, and overall cleanliness and hygiene—including food safety—can be concerns.
Environmental And Air Quality
- Causes
- The valley's geography, surrounded by hills on all sides, traps pollutants and prevents them from dispersing. The city has a large number of ageing vehicles running on diesel and outdated engines, which are a major source of black carbon, carbon monoxide, nitrogen dioxide and sulfur dioxide.
- Severity
- critical
- Health Risks
- In recent years, air pollution in Nepal has become a serious environmental and public health risk, with pollution levels 4.9 times higher than recommended by the WHO. Deteriorating air quality in Kathmandu is putting hundreds of thousands of Nepalese at risk of several health problems.
- Seasonal Pattern
- The problem is at its worst between January and May, and again in November and December, when cold, still air settles over the valley and traps pollutants close to the ground. August is historically the cleanest month, when monsoon rains and wind clear the air.
- Description
- In 2025, Kathmandu recorded an average PM2.5 concentration of 39 µg/m³, equivalent to an AQI of 109, placing it in the 'unhealthy for sensitive groups' category and 7.8 times higher than the WHO's annual guideline.
Emotional And Psychological Adjustment
- Description
- For most travelers it can be a difficult country to visit (emotionally), as you'll encounter lots of pollution, garbage, overt poverty, corruption, sick street dogs, etc. Some find, for example, the cultural differences between the concept of "personal space" and overall cleanliness/hygiene can be difficult to adapt to.
Foreigner Pricing And Administrative Friction
- Pricing
- Prices for foreigners are often higher, especially at attractions or in taxis.
- SIM Card Access
- SIM card access can be complicated without local help.
