Commonly Confused
Seasonal and seasonable are sometimes interchanged, probably because of their obvious connection with season. In edited prose and in formal speech these two adjectives are almost always distinguished. Seasonal describes phenomena that occur with or depend upon a season or the seasons: seasonal fluctuations in rainfall; seasonal sales. Seasonable in reference to weather means “suitable to or characteristic of the season”: a seasonable December; seasonable temperatures for July. Seasonable also has the sense “timely, opportune”: a seasonable offer of financial assistance.

Etymology
Origin of seasonal
Explanation
Seasonal things happen periodically, during a certain season. In most stores, Christmas decorations and candy canes are seasonal items. You'll probably find all kinds of fruit all year long in a large grocery store, but your local farmer's market most likely carries mainly seasonal fruit. This means they'll have apples in the fall, when they're in season, and strawberries in the spring. Workers are sometimes described as seasonal too — when they're employed just for the summer, for example: "The cafe hired lots of seasonal baristas in June."
