Average daytime highs in the coldest month, January, are around -4.0°C, while nightly lows drop to -8.5°C. During the winter months, temperature fluctuations between day and night are less pronounced than in summer, at about 4-5 degrees.

In Obninsk, precipitation is distributed fairly evenly throughout the year in terms of total volume, which ranges from 1 to 3 mm per month. However, the frequency—the number of days with rain or snow—varies significantly. The city does not have a traditional rainy or dry season, but some months do see more frequent and slightly heavier precipitation.

The winter period in Obninsk is characterized by snowfall, especially in January and December, when there are 15 days of precipitation each, with a monthly average of 2 mm. February is also snowy, with 11 days of precipitation and the same 2 mm. Given the low temperatures during these months (averaging -6.2°C to -4.0°C), precipitation falls primarily as snow. March, with 1 mm of precipitation over 10 days, is the "driest" month by volume, and snow or mixed precipitation is still likely early in the month. November (2 mm, 12 days) is also a transitional month when rain turns to snow.

With the arrival of warmer weather from April to October, precipitation falls as rain. The highest amount occurs in July — 3 mm, which is also one of the "wettest" in terms of frequency, with 15 rainy days. This suggests that summer rains can be more frequent, though not necessarily heavy. In the other warm months — April, May, June, August, and October — there is 2 mm of precipitation, with the number of rainy days ranging from 10 to 12. September stands out with the fewest days of precipitation — just 9 — at the same 2 mm level, making it relatively dry in terms of frequency.

Thus, while the total volume of precipitation in Obninsk is low and fairly stable month to month, its frequency changes. You can expect precipitation (snow or rain) most often in January, July, and December. The "driest" month by volume is March, while September has the fewest days of precipitation. Overall, the climate involves regular but mostly light precipitation throughout the year.

When planning a trip to Obninsk, it is important to choose the right wardrobe to stay comfortable in any weather. The key principle here is layering, as temperatures can fluctuate throughout the day. Since precipitation—while not always heavy (1-3 mm per month)—occurs quite frequently (9 to 15 days per month), a compact umbrella or a light waterproof jacket will be your best companions. Regardless of the season, be sure to pack comfortable walking shoes, as Obninsk and its surroundings are perfect for exploration on foot.

If your trip to Obninsk falls during the cold period from November to March—when average temperatures range from +0.3°C (in November) to -6.2°C (in January) and night frosts are common—you will need warm clothing. Your suitcase should include a warm winter jacket or down coat (preferably with a hood and windproof properties), sweaters, fleece layers, thermal underwear, a hat, a scarf, and gloves. Pay special attention to footwear; it should be warm and waterproof, especially if you are visiting during snowy months like January or December, when there are up to 15 days of precipitation.

For the summer months (June to August), when the average temperature in Obninsk stays between +16.9°C and +18.7°C and daytime highs can reach +23°C, lighter clothing is suitable: T-shirts, shorts, light trousers, or dresses. However, even in summer, evenings can be cool, and July, for example, can see up to 15 days of precipitation, so don't forget a light jacket, sweater, or cardigan. During the transitional seasons—spring (April-May) and autumn (September-October)—the weather is particularly changeable, making layered clothing essential. Sunscreen may also come in handy on clear summer days.
