Harvest Moon in September 2022

The Full Moon occurring this September will be the Harvest Moon. However, the October Full Moon can also be referred to as the Harvest Moon sometimes. Did Native Americans run out of names for the Full Moons by the end of the year? Read on to figure it out.


When is the Full Moon in September 2022?

This month, the Full Moon will occur on September 10 at 09:59 GMT (5:59 a.m. EDT). At this time, our natural satellite will lie in the constellation Aquarius. If the Moon is below the horizon at this time in your region, you’ll still have a chance to see it. To the naked eye, the Moon will appear completely round and bright the day before and after the event.

What is a Harvest Moon?

The Harvest Moon is the Full Moon closest to the autumnal equinox, which occurs in September in the Northern Hemisphere and in March in the Southern Hemisphere. Around this time, the Moon rises soon after sunset. In the past, this allowed farmers to work longer and harvest their crops in the evening, under the moonlight. That’s why the Full Moon occurring around the autumnal equinox was called the Harvest Moon.

Full Harvest Moon and autumn equinox

The Harvest Moon is not associated with a particular month, unlike the other Full Moon names. Instead, it is connected to the autumnal equinox: the Full Moon that is nearest to it takes on the name. In the Northern Hemisphere, the Harvest Moon usually occurs in September, but around every three-five years, it is in October. In the Southern Hemisphere, the Harvest Moon takes place either in March or April.

This year, the autumnal equinox in the Northern Hemisphere is on September 23 at 01:04 GMT (September 22, 9:04 p.m. EDT) – that’s why the Full Moon occurring on September 10 is the Harvest Moon. In the Southern Hemisphere, the autumnal equinox has already passed on March 20, at 15:33 GMT (11:33 a.m. EDT).

When is the next Harvest Moon?

In 2023, the Harvest Moon in the Northern Hemisphere will also take place in September. The exact time is September 29, 09:57 GMT (5:57 a.m. EDT). For the Southern Hemisphere, the date is March 7, 2023, at 19:40 GMT (3:40 p.m. EDT).

Why does the Harvest Moon look orange?

The Moon can have an orange hue while hanging low in the sky. The reason is that the blue wavelengths get scattered by the atmosphere, leaving more of the red wavelengths, so the Moon gets an orange or reddish glow. Pass our quiz and learn more about the possible colors of the Moon!
