Seasonal trends refer to patterns or changes that occur at specific times of the year, often influenced by factors like weather, holidays, and cultural events. For example, retail sales typically increase during the holiday season in December, while summer months may see a rise in outdoor activities and travel. These trends can affect various industries, including fashion, agriculture, and tourism. In agriculture, certain crops are planted and harvested based on seasonal cycles, while in fashion, clothing styles often change with the seasons, leading to distinct spring, summer, fall, and winter collections.
