Yes. Summer is a noun.
Direct objects are always nouns or pronouns.
I think you're confused about the 8 parts of speech (noun, pronoun, adjective, adverb, verb, preposition, conjunction, interjection) and parts of a sentence (subject, verb, direct object, etc.)
In this sentence, is summer a noun even though it is a direct object?
Go during the summer.
