The best time to visit Ulaangom is during the summer months, from June to August, when the weather is mildest and most pleasant for travel.
During this period, temperatures are generally warm, making it comfortable for exploring the city and its surroundings. The days are long, offering plenty of daylight for sightseeing and outdoor activities. This is also when the local landscape is at its greenest, which is particularly appealing for those interested in photography or nature walks.
For travellers interested in local cultural events, July is often a good month as it can coincide with Naadam, Mongolia's largest traditional festival, which features wrestling, horse racing, and archery. While the main Naadam festival is held in Ulaanbaatar, smaller, local celebrations often take place across the country, including in Ulaangom or nearby communities, offering a unique cultural experience.
If you're planning to explore the wider Uvs Province, the summer months are also ideal for visiting nearby natural attractions like Uvs Lake, a UNESCO World Heritage site, or the surrounding mountains and steppes.
