Illinois Experiences Coldest Mays on Record Since 1895
• Illinois has seen some notably cold Mays over the years, with data compiled by the National Centers for Environmental Information highlighting the coldest months since
• The rankings are based on average state temperatures, with May 1917 standing out as the coldest, recording an average temperature of 55.8°F (13.2°C). Other cold Mays include 1907 and 1924, both tied at 55.9°F (13.3°C). These months also experienced relatively low monthly high temperatures, such as 67.4°F (19.7°C) in May 1917, and significant precipitation levels, with May 1935 recording the highest at 7.83 inches. This historical data underscores the variability in spring weather patterns across Illinois.
Why It's Important?
The cold temperatures during these Mays likely impacted agriculture, particularly planting and growing conditions for crops sensitive to cooler weather. Additionally, colder springs can lead to delayed blooming of plants and trees, affecting ecosystems and local biodiversity. Precipitation levels, such as the 7.83 inches recorded in May 1935, may have contributed to localized flooding or waterlogging in agricultural fields, further complicating farming activities. Residents and businesses reliant on seasonal weather patterns may have faced challenges during these colder months.
