Seasonal describes anything that happens, appears, or is available only during certain times of the year. Strawberries are seasonal because they grow and taste best in late spring and early summer. Pumpkin spice lattes are seasonal drinks that coffee shops offer in autumn. The flu is seasonal because it spreads more easily in winter months.

Many jobs are seasonal too. A ski instructor works during winter, while a lifeguard typically works in summer. Stores often hire seasonal workers during the busy holiday shopping period in November and December.

Nature follows seasonal patterns. Birds migrate seasonally, heading south for winter and returning north for summer. Bears hibernate through winter, a seasonal behavior that helps them survive when food is scarce. Deciduous trees lose their leaves seasonally every fall.

Understanding what's seasonal helps you know when to expect certain foods, activities, or events. When something is described as seasonal, you know it won't last all year, which can make it feel more special when it arrives.
