Weather in April

April is wet and mild in Illinois, with the unabated advance of the spring season. Light snowfall occurs in the northern regions, but the ground is devoid of snow in the south. The thawing of snow is an excellent time to cruise on the lakes and rivers. Boating tours are readily available, and a tour down the river in the beautiful sunlight is an experience to cherish.
The average high temperatures are in the warm 57°F (13.9°C) to 65°F (18.3°C) range, while the average low temperatures register in the mild 37°F (2.8°C) to 47°F (8.3°C) range. The minimum 7 hours of sunlight is sufficient to shade off the bulky winter coats, but 10 to 12 wet days in the month ask for at least a rain jacket to combat the moistness.
The vast prairie is green to the hilt, as the rain and melting of snow fill the rivers, lakes, and streams with abundant freshwater. April is one of the best times to visit Illinois.
