The demand for insurance products and services generally experiences seasonality, influenced by various factors. Claims volumes often surge during specific seasons, such as hurricane, wildfire, flood, and tornado seasons, as well as during winter storms. Spring and summer are typically busy seasons for auto insurance, while April and October are considered the busiest months for home insurance. The health insurance sector usually peaks in the fourth quarter, and December is often a busier time for life insurance. Historically, insurance sales data often show higher sales in the first and fourth quarters compared to the second and third quarters.
