Harvest Moon Marks 2025’s First Supermoon, Beginning a Three-Month Streak

A near-perigee alignment makes the moon subtly larger, inaugurating a short monthly streak.

The Harvest Moon can occur in either September or October, whichever aligns closest to the autumnal equinox. October's full moon is known as the Hunter's Moon.

Overview

  • The full phase peaks at 11:48 p.m. ET on Oct. 6, with the moon appearing full again on Oct. 7 in many locations.
  • Perigee occurs about 2:49 p.m. AEDT on Oct. 7, placing the moon roughly 359,818 kilometers from Earth within 24 hours of fullness.
  • The next super full moons follow on Nov. 5 and Dec. 4, with some definitions also counting early January 2026.
  • The moon will rise near sunset and stay visible all night, appearing largest near the horizon due to the Moon illusion even though the size change is modest.
  • Slightly higher coastal tides are possible during this period, while the maximum difference between the largest supermoon and a distant micro-moon reaches about 14% in diameter and 30% in brightness.
