Seasonality of prices occurs when there is a time (season) of the year when prices are high or low compared to the annual average price. We typically see seasonality of prices in crops, fruits and vegetables, and some cuts of meat (steaks). An example of seasonality here in Georgia, the price of watermelons tends to be lower during the summer months when local melons are harvested and sold throughout the region. However, during winter months (or Georgia’s off-season for watermelons), prices are higher because there are fewer for sale, and grocers have to source them from other parts of the country or world.
