The 2026 Harvest Moon reaches its full phase on Saturday, September 26, peaking at 12:49 p.m. ET.[6] Observers in central Mexico can see the event with the naked eye at 18:29 local time on that date.[5] This full moon is the closest to the autumn equinox in the Northern Hemisphere and occurs in October approximately once every four years.[4] The only physical effect of this Sun-Earth-Moon alignment is the generation of spring tides, which happen twice a lunar month.[3]
