Weather in Uliastai

Planning a trip or simply want to stay informed about atmospheric changes? Here you will find the freshest information about the weather in the city of Uliastai, including current summaries and detailed forecasts.

The climate of the city of Uliastai can be characterised as sharply continental, distinguished by its harsh nature and significant temperature fluctuations. The weather here dictates its own rules: winter in this region of Mongolia is long and very cold, whilst summer is short but pleasant and moderately warm. Air humidity remains low throughout the year, making the climate quite dry.

Pronounced seasonality is the main feature of the local weather. From November to March, the city plunges into a deep freeze with average temperatures below -20°C, yet precipitation is practically absent during this time. Summer, conversely, delights with comfortable conditions: in July, the air warms up to an average of +21°C during the day, creating an ideal atmosphere for travel and outdoor walks.

A specific feature of Uliastai's climate is the phenomenally low amount of precipitation, even in the "wettest" summer months. Rains here are a great rarity, so tourists can count on a large number of clear days. Nevertheless, even at the height of summer, nights can be cool, so travellers are recommended to always have warm clothing with them.

The climate in this region is distinguished by a pronounced sharply continental nature, which means serious challenges with cold in winter and moderate, comfortable warmth in summer. Winter in the city of Uliastai is severe and prolonged. The coldest month is January, when the average temperature drops to -22.1°C, and night frosts often reach the mark of -29.2°C. Travellers planning a trip in the period from December to February should prepare for extreme conditions and carefully select their equipment.

The summer season here is short, but very pleasant for those who do not like exhausting heat. The warmest month is considered to be July with an average figure of 15.2°C. During the day, the air usually warms up to a comfortable 21.1°C, which creates ideal conditions for walks and exploring the nature of Mongolia. However, it is worth considering that even at the height of summer, nights remain cool: in June and August, minimum temperatures are around 6.8°C, so a warm sweater will be needed even in July.

The region is characterised by significant temperature fluctuations, both seasonal and daily. The difference between the daily maximum and nightly minimum at any time of the year averages 12–14 degrees. For example, in spring (in April and May), it may already be above zero during the day, whilst frosts still persist at night. Such a high amplitude requires tourists to observe the principle of layering in clothing to feel comfortable throughout the day.

The climate in Uliastai is distinguished by pronounced dryness, characteristic of many regions of Mongolia. Precipitation here is not a very frequent phenomenon, and it is distributed unevenly across the seasons. The winter months, from November to March, pass practically without precipitation: the average moisture level tends towards zero, and the number of days with precipitation is minimal (2–3 days per month). Due to low temperatures reaching -29°C, any moisture during this period falls exclusively in the form of light snow or frost.

The main part of precipitation falls during the warm period of the year. Summer, especially July and August, is considered the "wettest" time, although this definition is quite relative. In these months, the number of rainy days reaches a maximum — about 10 days per month. However, rains usually have a short-term character; they are not prolonged and are rarely heavy, as the total volume of precipitation remains low.

In the transitional seasons, spring and autumn, the weather is changeable. In April, May, and October, the probability of precipitation increases compared to winter (up to 5–7 days per month). At this time, when the thermometer fluctuates around the zero mark, rain can alternate with wet snow. Travellers should be prepared for the fact that even in the "rainy season", the air remains sufficiently dry.

When preparing for a trip to Uliastai, it is important to remember the sharply continental climate of this region, where the weather can be unpredictable. The main principle when choosing clothes is layering. Winters here are severe and long, with temperatures often dropping below -20°C, so in the cold season, be sure to take high-quality thermal underwear, woollen sweaters, a windproof down jacket, a warm hat, a scarf, and mittens. Pay special attention to footwear: it should be insulated, comfortable, and have a non-slip sole.

Summer in Mongolia is generally not hot and is comfortable for walks, however, temperature differences between day and night can be substantial. Even in July and August, you will need not only light t-shirts and trousers but also a fleece jacket or windbreaker for cool evenings. Since the city is located in an area with high solar activity, be sure to pack sunglasses, a head covering, and cream with high SPF in your suitcase to protect your skin from ultraviolet radiation.

Although the amount of precipitation is small, short-term rains are possible in summer, so a compact raincoat or a light waterproof jacket will not be superfluous. It is also recommended to take moisturising skin products and lip balm with you, as the air here is quite dry all year round. For long hiking walks in the surroundings, choose well-worn trekking shoes that provide reliable foot support.
