Supermoon 2025: Check Dates, Times, and U.S. Visibility Guide (For Harvest to Wolf Moon)

Supermoon 2025: The night sky is about to treat US observers to one of the rarest celestial events of the decade: a series of four supermoons in a row. Beginning with the iconic Harvest supermoon in October, this phenomenal string of full moons will close out 2025 and usher in the New Year.

For anyone interested in astronomy, these back-to-back moons, when the Moon is near its closest point to Eart(perigee), are must-see events. This definitive guide provides all the official supermoon 2025 dates, peak US times, and the essential viewing tips you need.

Lean exactly what a supermoon is and prepare to witness the brightest, largest full moons of the season.

What Makes the Four Supermoon in a Row so Rare?

The term Supermoon describes a Full Moon (or New Moon) that occurs when the Moon is within 90% of its closest approach to Earth, a point called perigee. Because it is so close, the Moon looks up to 14% bigger and 30% brighter than the year's least-bright Moon, which is a Micromoon.

While Supermoons occur three or four times almost every year, having four supermoons in a row is a sequence that only happens due to a precise rhythm between the Moon's phases and its elliptical orbit. The time it takes for a moon to go from perigee to perigee (an anomalistic month) is slightly shorter than the time between two Full Moons (a synodic month).

Over time, these cycles gradually align, causing multiple consecutive full moons to occur near their closest point to Earth. This Harvest supermoon sequence is a perfect example of this alignment. Notably, the November Beaver Supermoon will be the single closest full moon of the entire series.

BonusCelestial Event 2025: Comets and Orionid Meteor Shower!

October’s darkness brings more than just the first supermoon of 2025. US sky watchers have an unusual opportunity to view the Orionid meteor shower alongside two new comets, C/2025 A6 (Lemmon) and C/2025 R2 (SWAN).

• Comet Viewing: Both Comets, SWAN and Lemmon, are expected to reach magnitude +4 or brighter around October 21, potentially making them visible to the naked eye under dark skies.

• Meteor Shower Peak: The reliable Orionid meteor shower, debris from Halley's Comet, peaks on the night of October 21-22. This timing coincides perfectly with the New Moon, meaning zero moonlight interference and the best possible viewing conditions for streaks of light.

• Planetary Conjunctions: Look for Saturn, which will be visible near the Harvest Supermoon on October 6th, adding a planet to the spectacular scene.

How to Watch the October Supermoon?

You don't need a telescope to enjoy the extra brightness and apparent size of the Supermoon, but following these tips will guarantee the best view for How to Watch Supermoon in the US nights:

• Prioritize Moonrise: The Moon appears largest and most dramatic when it is low on the horizon, just after sunset. This is due to the "Moon Illusion," which tricks your brain into comparing it to nearby foreground objects (trees, buildings). For the October moon (Harvest Supermoon), this happens shortly after sunset on October 6th across the entire US.

• Find an Open Horizon: Head to a spot with unobstructed views of the eastern horizon, a beach, hilltop, or large field away from city lights works best. Light pollution dramatically reduces the visual impact of the Moon's extra brightness.

• Use Local Times: Remember that the peak time (listed in ET) is when the Moon is technically 100% full. If you are on the West Coast, subtract three hours to get the local Pacific Time. Always check a local moonrise and moonset calculator for precise viewing windows in your state.
