We carried out a systematic study of full-orbit phase curves for knowntransiting systems in the northern ecliptic sky that were observed during Year2 of the TESS primary mission. We applied the same methodology for targetselection, data processing, and light-curve fitting as we did in our Year 1study. Out of the 15 transiting systems selected for analysis, seven - HAT-P-7,KELT-1, KELT-9, KELT-16, KELT-20, Kepler-13A, and WASP-12 - show statisticallysignificant secondary eclipses and day-night atmospheric brightnessmodulations. Small eastward dayside hotspot offsets were measured for KELT-9band WASP-12b. KELT-1, Kepler-13A, and WASP-12 show additional phase-curvevariability attributed to the tidal distortion of the host star; the amplitudesof these signals are consistent with theoretical predictions. We combinedoccultation measurements from TESS and Spitzer to compute dayside brightnesstemperatures, TESS-band geometric albedos, Bond albedos, and phase integralsfor several systems. The new albedo values solidify the previously reportedtrend between dayside temperature and geometric albedo for planets with$1500<T_{\mathrm{day}}<3000$ K. For Kepler-13Ab, we carried out an atmosphericretrieval of the full secondary eclipse spectrum, which revealed a non-invertedtemperature-pressure profile, significant H$_{2}$O and K absorption in thenear-infrared, evidence for strong optical atmospheric opacity due to sodium,and a confirmation of the high geometric albedo inferred from our simpleranalysis. We explore the implications of the phase integrals (ratios of Bond togeometric albedos) for understanding exoplanet clouds. We also report updatedtransit ephemerides for all of the systems studied in this work.
