Weather in Butte

Planning your visit to Butte? Here you will find the latest information on weather conditions, including current data and detailed forecasts to help you better prepare for your trip.

The climate of Butte can be characterised as cold semi-arid, which is typical for the mountainous areas of this US region. All four seasons are distinct here, though winters are generally long and harsh, whilst summers are short but very comfortable. Travellers should be prepared for significant temperature fluctuations, which create the city's unique, invigorating atmosphere.

The winter months here are truly frosty: the average temperature often stays below freezing, dropping to -13°C on the coldest nights of January and February. Summer, on the other hand, delights with pleasant warmth without exhausting heat. In July and August, the air warms up to a comfortable 25°C during the day, making this the ideal time for walks, although nights remain fresh even at the height of the season.

A feature of the local weather is a rather wet spring and early summer: May and June lead in the number of days with precipitation, although the total volume remains small. Autumn arrives rapidly, bringing noticeable coolness as early as September and the first frosts by November. When planning a trip, it is important to consider these contrasts and always have warm clothing on hand, especially for evening outings.

The climate in Butte is distinguished by marked seasonality, typical of mountain regions. The coldest period of the year is winter, especially January and February, when average temperatures drop to -7°C... -8°C. During this time, the city is gripped by real frosts: night-time figures often reach -13°C, so travellers should prepare for harsh conditions and stock up on high-quality warm clothing.

Summer, conversely, brings pleasant and moderate warmth without stifling heat. The warmest months are traditionally July and August, when the daytime air warms up to an average of +25°C... +26°C. This is the most comfortable time to visit, allowing you to enjoy walks in the fresh air. The transitional seasons — spring and autumn — are quite cool, with a gradual change in temperatures.

An important feature of the local temperature regime is the significant fluctuation between day and night figures. Even in the height of summer, when it can be sunny and warm during the day, nights remain quite fresh: in July and August, the temperature after sunset can drop to +9°C... +10°C. Such contrast requires a flexible approach to wardrobe from tourists to feel comfortable at any time of day.

Precipitation in Butte is distributed rather specifically throughout the year: there is no pronounced season of tropical downpours here, but the number of overcast days can be significant. In winter, from November to March, due to persistent sub-zero temperatures, precipitation falls mainly as snow. Although the total volume of moisture in millimetres is small, regular snowfalls (about 8–13 days with precipitation per month) form classic winter landscapes.

Late spring and early summer are considered the wettest period of the year. May is the undisputed leader in precipitation frequency: rain or sleet can occur up to 19 days a month. June is also characterised by increased humidity — precipitation is observed for about 15 days. However, it is worth noting that even during this period, rains are often short-lived and not too intense.

The driest and most stable time to visit can be called late summer and early autumn. In September, the lowest number of inclement days is recorded — only about 7 for the month. July and August are also favourable for tourism: rains occur less frequently, and comfortable warm weather allows you to explore the city's attractions with pleasure.

Winter in Butte is quite severe and long, so if your trip is planned for the period from November to March, be sure to take care of reliable warm gear. The average temperature in these months consistently stays below freezing, and at night it can drop to -13°C. The basis of your wardrobe should be a high-quality down jacket or insulated parka, thermal underwear, and woollen jumpers. Don't forget accessories: a hat, scarf, and warm gloves are mandatory. Also critically important is comfortable waterproof footwear with non-slip soles for moving comfortably along snowy streets.

Summer here is moderately warm and pleasant, with daytime temperatures around +25°C in July and August, however, the weather can be changeable. Even in the very height of summer, nights remain cool (around +9°C), so the principle of layering in clothing will be the best solution. Take light items with you, but be sure to complement them with a fleece jacket, cardigan, or denim jacket for evening walks. Spring, especially May, is distinguished by frequent precipitation (up to 19 rainy days), so a windproof jacket, raincoat, or sturdy umbrella will become your best helpers at this time of year.

Regardless of the season, to explore the city and its picturesque surroundings, you will need comfortable footwear for walking, designed for long strolls. Considering that the city is located in a mountainous area, the sun here can be active even at low temperatures. Therefore, we recommend packing sunglasses and SPF cream in your luggage to protect your skin and eyes during open-air excursions.
