When planning a trip to South Bend, it is important to consider the distinct change of seasons to pack your suitcase correctly. In winter (from December to February), early spring (March), and late autumn (November), it is quite cool here; average temperatures fluctuate around zero and can drop below -5°C. During this period, you will need a warm winter jacket (possibly windproof), a hat, gloves, a scarf, and waterproof shoes, as precipitation in the form of rain or snow is not uncommon, averaging 11-13 days per month. The principle of layering in clothing will be very handy: thermal underwear, a fleece jacket, and a sweater will help retain warmth and ensure comfort even in cool and potentially windy weather.

From April to October, the weather in South Bend becomes significantly warmer. Summer (June-August) is warm here, with average temperatures above 20°C and maximums reaching 27-28°C. For this time of year, light clothing is suitable: T-shirts, shorts, dresses. However, considering that rainy days happen throughout the year (from 10 to 15 days a month with 2-5 mm of precipitation), a light waterproof jacket or windbreaker, as well as a compact umbrella, will become your reliable companions. In spring and autumn, when the temperature is more variable, layering is also relevant – for example, a light sweater or cardigan will be useful for evening walks. Regardless of the season, comfortable walking shoes are a must-have, and on sunny summer days, do not forget sunscreen and a hat/cap.
