For example, in the summer months, the difference between the average minimum and maximum temperature is about 6-7°C (for instance, in July from 19.5°C to 25.3°C). In the winter months, this difference is somewhat smaller, around 5-6°C (for example, in January from -5.5°C to -0.3°C).

Monthly precipitation fluctuates slightly, ranging from 2 to 4 mm. The highest amount of precipitation, about 4 mm, usually falls in April, May, and October. The "driest" months in terms of precipitation are January, February, March, August, November, and December, when an average of 2 mm falls.

The nature of precipitation in Gurnee depends on the time of year and temperature. Given the average temperatures, in winter months like January (average temperature -2.9°C), February (-1.8°C), and December (0.9°C), precipitation is most likely to fall as snow or sleet. In March, with an average temperature around 3.0°C, both rain and late snowfalls are possible. In the remaining months, from April to November, when temperatures are above freezing, precipitation is usually light rain or drizzle, which corresponds to the low overall volume of moisture.

When planning a trip to Gurnee, it's important to consider the changeable weather characteristic of a continental climate. The key principle when packing should be layering. This will allow you to easily adapt to temperature changes throughout the day and between seasons. Regardless of the time of year, be sure to bring comfortable walking shoes, as you'll surely want to explore the city. Given that precipitation, while not heavy (2-4 mm per month), occurs regularly (8 to 13 days with precipitation per month), a light umbrella or waterproof jacket will be very handy.

For the winter months (December-February), when average temperatures drop below freezing (to -2.9°C in January) and minimums can reach -5.5°C, warm clothes are essential: a winter jacket, hat, gloves, scarf, and possibly thermal underwear. Precipitation during this time is likely to be snow. In summer (June-August), the weather in Gurnee is warm, with average temperatures around 19-22°C and highs of up to 25°C. You will need light clothing (T-shirts, shorts, dresses), a hat, sunglasses, and sunscreen. Even on summer evenings, a light sweater or windbreaker might come in handy as temperatures can drop.

In spring (March-May) and autumn (September-November), the weather in Gurnee is most changeable. In March, it can still be chilly (average temperature around 3°C), while in May and September, it is already or still quite warm (average temperatures 13.2°C and 19.6°C respectively). In November, the approach of winter is felt (average temperature 5.3°C). During these periods, layered clothing is especially relevant: T-shirts, long-sleeved shirts, sweaters, and a mid-season jacket. Waterproof outerwear will also be useful due to possible rain, especially in April, May, and October, when the number of days with precipitation reaches 12-13.
