Summer months in the city are usually warm and quite humid, creating wonderful conditions for outdoor recreation, while winters can be harsh and snowy.

Winter in the USA, especially in northern Illinois, can be severe. The coldest month is January, when the average daily temperature drops to -3.8°C, and nighttime frosts can reach -7...-10°C.

The shoulder seasons in the city are known for their unpredictability.

Winter months bring heavy snowfall, transforming the area into a true winter wonderland. From December to February, precipitation falls mainly as snow, with an average of about 8-10 "wet" days per month.

Nevertheless, travelers should be prepared for cloud cover, which is a frequent visitor to this region at any time of year.

When packing for Round Lake Beach, follow the principle of layering. For a summer trip to the USA, lightweight clothing made from natural fabrics is ideal, but don't forget to bring a light jacket for cool evenings and sunscreen with high SPF. The sun can be quite intense during this time of year, so a hat and quality sunglasses will also come in handy.

A winter visit requires more serious preparation: a warm coat or down jacket, a hat, scarf, and gloves are essential for protection against the cold. Pay special attention to waterproof and insulated footwear, as snowfall in Illinois can be significant. During the shoulder seasons of spring and autumn, a windbreaker or a mid-season jacket is the best choice.

Since the city receives regular precipitation throughout the year, a compact umbrella or a high-quality raincoat should always be close at hand. It is also recommended to choose comfortable walking shoes, as the local landscape invites long walks in the fresh air, regardless of nature's whims.
