[[File:Köppen Climate Types Delaware.png|thumb|The Köppen climate classification for Delaware]]
Since almost all of Delaware is a part of the [[Atlantic coastal plain]], the effects of the ocean moderate its climate. The state lies in the [[humid subtropical climate]] (Köppen ''Cfa'') zone. Despite its small size (roughly {{convert|100|mi|km}} from its northernmost to southernmost points), there is significant variation in mean temperature and amount of snowfall between Sussex County and New Castle County. Moderated by the Atlantic Ocean and [[Delaware Bay]], the southern portion of the state has a milder climate and a longer growing season than the northern portion of the state.

Summers are long, hot, and humid in Delaware, often with intense (but brief) late day thundershowers. Delaware averages 2,300 hrs of sunshine annually (higher than the USA average). Winters are modestly cool to cold in northern Delaware, and cool to mild in southern Delaware. The normal seasonal snowfall ranges from about 20.0 inches in Wilmington to only 10.0 inches in Lewes. In many winters no snow will fall in coastal Delaware. Northern Delaware falls into USDA Garden Zone 7a, while southern and coastal areas fall into USDA zone 7b and 8a. The milder climate in southern Delaware allows for [[subtropical]] [[flora]] such as the [[windmill palm]], [[needle palm]], and [[dwarf palmetto]].

Delaware's all-time record high of {{convert|110|F|C}} was recorded at [[Millsboro, Delaware|Millsboro]] on July 21, 1930. The all-time record low of {{convert|-17|F|C}} was also recorded at Millsboro, on January 17, 1893. The [[hardiness zone]]s are 7B and 8A at the [[Delaware Beaches]].
