Summer Weather in Mongolia – June, July, August

Summer in Mongolia, from June to August, offers the best weather for travelers, with long sunny days, mild to hot temperatures, and relatively little rainfall. June is fresh and comfortable, July brings the warmest conditions, and August stays pleasant while hinting at the coming autumn. It’s the ideal season for exploring both Ulaanbaatar and the vast countryside.

In summer, Mongolia’s temperatures generally range between 10–30°C (50–86°F), with cooler nights and hotter days, especially in the Gobi Desert where it can climb above 35°C (95°F).

Weather in June

Mild and comfortable, with temperatures ranging from 10–25°C (50–77°F). Skies are mostly clear, though nights can still be chilly in the steppe and mountain regions.

Pack layers, as temperatures can shift from warm days to chilly evenings. A light jacket or fleece is essential, along with breathable shirts and trousers for daytime comfort.

Weather in July

The hottest month of the year, averaging 15–30°C (59–86°F). The Gobi Desert can exceed 35°C (95°F). Rain showers are occasional but short, and the days are long and sunny.

Focus on light, airy clothing such as T-shirts, shorts, and breathable fabrics for the hot days. A hat, sunglasses, and sunscreen are musts, but also carry a light rain jacket for sudden showers.

Weather in August

Still warm, typically 12–25°C (54–77°F), though nights begin to cool as autumn approaches. Rainfall is slightly more frequent than in July, making landscapes greener and fresher.

Bring a mix of summer and autumn wear. While days are still warm, evenings cool down, so a sweater or light jacket is handy. A raincoat or waterproof layer is also recommended due to increased rainfall.
