Winter months, such as January, February, and December, are characterized by average temperatures below freezing (from -4.9°C to -0.4°C), so precipitation during this time (about 2 mm per month) falls mainly as snow. Light snowfalls or snow grains are typical for the period from December to February and are also possible in early March, when minimum temperatures can still drop below zero.

The highest amount of precipitation, though remaining moderate, usually falls during the spring-summer period and early autumn. May, June, and September are the months with the highest average precipitation, reaching 4 mm. April and May also see the highest number of days with precipitation—about 13 days each month—with 3 mm falling in April and 4 mm in May. In the summer months (June, July, August), precipitation falls as rain, which may be brief given the higher temperatures. June receives 4 mm of precipitation over 12 days, while July and August receive 3 mm over 11 and 10 days respectively.

The driest months by precipitation amount (2 mm) are January, February, March, November, and December. In terms of frequency, November stands out as the month with the fewest wet days—averaging just 7 days.

When planning a trip to Rockford, it is important to consider its continental climate with four distinct seasons, which directly influences your choice of wardrobe. Regardless of the time of year, comfortable walking shoes will be your best companion. Due to frequent, though not heavy, precipitation (7-13 wet days per month), a light folding umbrella or a waterproof jacket will be very useful. Layering your clothes will help you easily adapt to temperature changes throughout the day.

Winter months (December-February) in Rockford are cold, with average temperatures below zero (from -4.9°C to -0.4°C) and lows reaching -8.7°C. You will need a warm winter jacket, hat, gloves, scarf, and possibly thermal underwear. Spring (March-May) and autumn (September-November) are characterized by changeable weather. At the beginning and end of these seasons, it can be chilly (average temperature in March is +3.9°C, in November +4.3°C), so it is worth bringing a mid-season jacket and sweaters. In April, May, September, and October, the weather is milder, but evenings can still be cool.

Summer (June-August) in Rockford is warm, with average temperatures from +22°C to +23.6°C, and maximums can reach +28.4°C. Light clothing such as T-shirts, shorts, dresses, and sandals is suitable for this period. Don't forget sunscreen, a hat, and sunglasses. Despite the warmth, evening chills or air-conditioned rooms may require a light sweater or cardigan. Given that even in summer there are 10-12 wet days per month, a light windbreaker or umbrella won't go to waste.
