The Biggest Feature of Mongolia's Weather: Not Simply Cold, but Large Temperature Swings and Strong Winds
When many people think of Mongolia, their first reaction is "it must be very cold."But in reality, what you most need to adapt to when travelling in Mongolia is often not simply the low temperatures, but rather the large day-night temperature swings, noticeable winds, and dry climate. Even in summer, it can be quite comfortable when the sun is out during the day; but in the early morning, evening, and night, or in open environments like the grasslands, sand dunes, and ger camps, it usually feels noticeably colder. When preparing your outfits for Mongolia, keep these key points in mind:- Daytime and nighttime feel very different
- The wind on the grasslands and dunes is usually more noticeable than you'd expect
- Dryness and UV rays also affect overall comfort
- Rather than simply dressing thickly, dressing in layers matters more
What to Wear in Mongolia? Layering Is the Most Practical Approach
The most practical way to dress for travelling in Mongolia is usually not simply wearing thick clothes, but adopting an easy-to-adjust layered approach, which better handles the changes in how it feels between daytime, mornings and evenings, and different types of terrain. You can simply think of it as three layers:Outfit Tips for Travelling in Mongolia: The Three-Layer Method
| Clothing Layer | Main Function | Common Choices |
| Base Layer | Keep warm and dry | Thermal wear, warm base layers, merino wool |
| Mid Layer | Trap body heat | Fleece jacket, lightweight down, warm mid-layer top |
| Outer Layer | Block wind and prevent the wind-chill effect | Windproof jacket, lightweight water-repellent outer shell |
Is thermal wear enough for Mongolia?
Many people ask before setting off: "Will bringing thermal wear be enough for Mongolia?" The answer is usually: not quite. Because what a trip to Mongolia really requires you to deal with is often not just the low temperatures, but:- Large day-night temperature swings
- Noticeable wind
- Long hours of outdoor activities
- The chill of open environments such as grasslands and sand dunes
- A base layer
- Paired with a warm mid layer
- And topped with a windproof outer layer
Can you wear only short sleeves when visiting Mongolia in summer?
During the day it may be possible, but we don't recommend bringing only short sleeves. When there is sunshine during a Mongolian summer day, it usually feels quite comfortable, and at times you may even find it a little warm. But as soon as the sun goes down, the wind picks up, or you enter open environments such as grasslands, sand dunes, or gers, it usually turns cool very quickly. A more reliable approach is usually to:- Wear short sleeves or thin long sleeves during the day
- Carry a warm layer or jacket with you when going out
- Remember to add a windproof layer in the mornings and evenings and during outdoor activities
How do you stay warm and windproof in Mongolia?
What you really need to deal with in Mongolia is often not simply low temperatures, but the wind and the temperature swings. If you feel the cold easily, or your itinerary includes a lot of outdoor activities, you can start with the following approach for a quick understanding:Common scenarios in Mongolia travel and clothing suggestions
| Situation | How It Feels | Suggested Clothing |
| Daytime in the city / when the sun is out | Usually comfortable, even on the warm side | A short-sleeve or light long-sleeve top is fine; keep a jacket handy |
| Grasslands / sand dunes / open areas | Noticeable wind, feels colder quickly | Add a windproof jacket to avoid getting chilled by the wind |
| Early morning / evening / night | Temperature drops noticeably | Add a warm mid-layer, such as fleece or lightweight down |
| Staying in a ger / long periods outdoors | Temperature swings and wind are even more noticeable | Dress in layers, keeping both warmth and wind protection in mind |
For a trip to Mongolia, you don't need to pack a lot of clothing — but you need to pack the right things
The key to dressing for Mongolia usually isn't bringing a lot, but bringing just the right amount. In short, here's roughly what you can prepare:- Short-sleeved or lightweight long-sleeved tops
- A warm mid-layer
- A windproof jacket
- Long trousers and comfortable walking shoes
- A hat, sunglasses and sun protection
Mongolia Travel Weather & Clothing Q&A
Q1: Is it cold at night in Mongolia in July?
A: Usually yes. Even though July is one of the most comfortable and travel-friendly months in Mongolia, mornings, evenings and nights generally still feel cool, which is especially noticeable in the grasslands, in a ger or in open areas. If you have outdoor activities or accommodation arrangements at night, it's advisable to prepare a warm layer and a jacket.Q2: Is it cold sleeping in a ger at night?
A: It can be, especially in the early morning hours.How a ger feels depends on that day's temperature, the wind and the region. Even if the day is comfortable, the night and early morning can still feel cold. It's advisable to prepare a set of warm clothing you can put on while sleeping, so you'll sleep more comfortably.Q3: Do I need to bring a down jacket to Mongolia?
A：You don't necessarily need a heavy down jacket, but we recommend bringing at least a lightweight warm jacket. If you're travelling in summer, you usually won't need a very thick winter down jacket, but a lightweight down jacket or a warm mid-layer often comes in very handy, especially in the mornings and evenings and during outdoor activities.Q4: Can I wear sneakers in Mongolia?
A: Yes, but we recommend choosing shoes that are comfortable to walk in and have good grip.If your itinerary involves walking across grasslands, sand, gravel paths, or includes plenty of outdoor activities, shoes with stable soles that hold up to lots of walking will be much more comfortable. You don't necessarily need professional hiking boots, but we don't really recommend wearing shoes that are too thin, too slippery, or lacking in support.Q5: Mongolia's climate is dry — what else should I keep in mind?
A：Moisturising and sun protection are usually very important. Mongolia's climate is generally on the dry side, and with strong sunshine and noticeable winds, the discomfort travellers commonly experience isn't necessarily the cold, but rather chapped lips, dry skin, or sunburn. So in addition to clothing, we also recommend bringing lip balm, moisturisers, and sun protection products.Q6: Is rain in Mongolia a big hassle?
A：It usually won't affect your whole trip. Mongolia sometimes gets brief showers in summer, but in most cases it won't rain continuously all day. If your itinerary includes outdoor activities, bringing a lightweight water-repellent outer layer or a packable piece of rain gear is usually more than enough.Head to Mongolia with DeWonder
