E.C. Marchant, Commentary on Thucydides: Book 3

First Entry:

θέρους—Thuc. divides the year into θέρος, consisting of about eight months (Elaphebohon to Pyanepsion) and χειμών, consisting of about four (Maimacterion to Anthesterion).

ἅμα τῷ σίτῳ ἀκμάζοντι—‘just when the corn was ripening’; about the middle of May, 428 B.C., before the harvest (καρποῦ ξυγκομιδή).
