I heard in the Rebbe’s name: A Jew’s main devotion in the winter is to wake up at midnight [and say Tikkun Chatzot , the midnight service (cf. Magen Avraham 1:4) ]. In the summer, when the nights are very short [and so awakening at midnight is not practiced in the Diaspora 370 See Likutey Moharan I, 149; Likutey Halakhot , Rosh HaShanah 3:7; She'arit Yisrael 125. ], one should still be careful to wake up early, at the crack of dawn.
