October 24, 2018 brings the Northern Hemisphere’s full Hunter’s Moon. For this hemisphere, it’s the second full moon of autumn (or second full moon after our autumn equinox). For the Southern Hemisphere, it’s the second full moon of spring.
By definition, the Hunter’s Moon is the full moon immediately following the Harvest Moon, which is the full moon closest to the autumn equinox.
If you live in the Southern Hemisphere, your full Harvest and Hunter’s Moons will come six lunar months (six full moons) from now, on March 21 and April 19, 2019, respectively.
At the vicinity of all full moons, the moon rises in the east around sunset, climbs highest up for the night around midnight and sets in the west around sunrise. On average, the moon rises about 50 minutes later with each passing day.
That’s not the case around the time of the Harvest or Hunter’s Moons. Around these full moons, the time between successive moonrises is less, more like 30 minutes at some latitudes.
Meanwhile, for the Southern Hemisphere now, the time between successive moonrises is greater than usual.
This October, 2018, Hunter’s Moon in particular swings a maximum of 5 degrees (10 moon diameters) south of the ecliptic (Earth’s orbital plane). For that reason, this particular full moon rises after sunset at northerly latitudes yet before sunset at southerly latitudes.
That complication aside, however, if you watch the moonrise each day this coming week – assuming you’re in the Northern Hemisphere – you’ll see the moon rising farther north (or farther left) along the eastern horizon.
In a nutshell – for both hemispheres – autumn full moons herald a series of earlier-than-average moonrises, while springtime full moons bring a series of later-than-average moonrises.

The farther north that you live from the equator, the greater the Hunter’s Moon effect. For example, at Seattle, Washington (48 degrees north latitude), the moon rises about 30 to 35 minutes later daily for the next few days. At a far northern outpost – such as Arctic Village, Alaska (68 degrees north latitude) – the moon rises at or near the same time for days on end.
The moon turns precisely full on October 24 at 16:45 Universal Time. At United States time zones, that places the time of full moon on October 24, 2018, at 12:45 p.m. EDT, 11:45 a.m. CDT, 10:45 a.m. MDT, 9:45 a.m. PDT, 8:45 a.m. AKDT (Alaskan Daylight Time) and 6:45 a.m. HST (Hawaiian Standard Time).
Bottom line: On the night of October 24, 2018 (morning of October 25), watch the Harvest Moon light up the nighttime from dusk until dawn!
