September’s Fall Equinox Is Coming: What to Know and What It Looks Like
Later this month, you could experience an equinox sunrise, which marks the arrival of fall in the Northern Hemisphere.
Labor Day has come and gone, and school is back in session. Though the leaves have yet to start turning, fall is making its way here. The official arrival of the season is the autumnal equinox, which occurs in the Northern Hemisphere in September.
After a hot summer, the fall equinox marks a welcome shift in the seasons for many folks. But what exactly is an equinox? It’s all about Earth and its relationship with the sun. Here’s how to understand, visualize and celebrate the autumnal equinox.
When is the fall equinox?
This year, the autumnal equinox in the Northern Hemisphere falls on Monday, Sept. 22. If you want to be extra specific and mark it on your calendar, mark it for 11:19 a.m. PT.
Dates can shift slightly for equinoxes depending on the year, but it’s always around this time in September. The next vernal equinox in the Northern Hemisphere takes place on March 20, 2026, and will mark the start of spring.
What does the September equinox look like?
Wherever you are on Earth on the day of the equinox (and whether it’s a spring or fall equinox, depending on which hemisphere you live in), the sun will rise as close to east and set as close to west as possible, making it a foolproof compass. Go outside and watch the sunset and sunrise, and make a note of the landmarks in front of the sun. That way, you’ll always know what exactly is west and east.
The two annual equinoxes also feature the fastest sunrise and sunset of the year, with the sun taking just a few seconds to appear and disappear. That’s because this is the steepest angle at which the sun rises and sets during the year.
What is the fall equinox?
The meaning of equinox is right there in the name: a combination of the Latin words for equal and night.
«There are only two times of the year when the Earth’s axis is tilted neither toward nor away from the sun, resulting in a ‘nearly’ equal amount of daylight and darkness at all latitudes,» the National Weather Service said in an explainer about the seasons.
The Earth spins on an axis (imagine a line running from pole to pole) and the planet sports a jaunty 23.5-degree tilt. The tilt is what gives us seasons. As the Earth orbits the sun, the tilt means some areas of the planet get more direct sunlight than others. That’s how it can be summer in the Northern Hemisphere (tilted toward the sun) and winter in the Southern Hemisphere (tilted away from the sun) at the same time. During the equinox, the sun shines straight at the equator and gives equal love to the two hemispheres.
Other planets that are also tilted on their axes of rotation also experience equinoxes. The time scales can be very different, however. An equinox on Saturn only comes around about every 15 Earth years. That means each season lasts for over seven years on Saturn. It’s even wilder on Neptune, which has seasons that last decades. We can be grateful for the relatively short seasons on our planet.
How is equinox different from solstice?
As with equinoxes, solstices are associated with Earth’s tilt, but instead of daylight and nighttime being even, the days and nights are at their extremes. The winter solstice is the shortest day of the year, while the summer solstice is the longest. This year, the winter solstice for the Northern Hemisphere falls on Sunday, Dec. 21.
See equinoxes from space
Earth-watching satellites up in orbit have a unique view of the equinox. A NASA Earth Observatory video shows Earth from space and how the positioning of the sun’s light shifts with the changing of the seasons. It’s a great way to visualize what’s happening during our planet’s orbit around the sun.
How to celebrate the fall equinox
Equinoxes aren’t like eclipses or meteors. There isn’t a big wow moment when you see something spectacular. The fall equinox this year will look like any other day, but it’s a handy way to mark the changing of the astronomical seasons. You can go around and declare, «It’s officially the first day of autumn!» How you celebrate is up to you. Here’s a suggestion: Put on your favorite sweater, go for a scenic foliage drive and sip a pumpkin spice latte to welcome fall in style.

Here’s the Best Time to Spot November’s Supermoon, the Brightest Moon of 2025
Does the moon look brighter and bigger? It’s not just you — here’s why this month’s supermoon is even more super.
November is a great month for skygazers, featuring a trio of meteor showers and the return of the northern hemisphere winter constellations. This week, it also features the second of four consecutive supermoons. This month’s supermoon will happen on Nov. 4-5, and November’s beaver moon is special because it’ll be the brightest full moon of 2025.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
In addition to being a supermoon, November’s full moon is known as the beaver moon. There is some debate as to why it was named this way. Some believe that this was the best time of year in the old days to set beaver traps to get pelts for winter clothing. Others believe that it coincides with the busiest part of the year for beavers, who are now stocking their lodges with supplies for the upcoming winter.
The brightest supermoon: When’s the best time to see it?
The moon will reach peak illumination at 8:19 a.m. ET on Nov. 5, making the evening of Nov. 4 and the morning of Nov. 5 the best times to view the moon.
Since moon phases shift slowly, the moon will appear almost full for nearly a week. If you are unable to view the full moon on its best night due to weather or other reasons, you can still see a mostly full moon at any point from Nov. 3 to Nov. 8.
For all of those days, the moon will be measurably brighter in the night sky compared to any other full moon in 2025. The reason for this is because of the moon’s elliptical orbit. Since it’s not a perfect circle, the moon’s 27.3-day journey around the Earth brings it closer to us on some days, a phenomenon known as perigee. If there is a full moon during this time, it’s branded as a «perigean full moon,» which you may know better as a supermoon.
Not all supermoons are equal, and November’s will be a little more special than others. According to The Farmer’s Almanac, the beaver moon will be a scant 221,817 miles away from Earth, making it the closest full moon of the year. That means it’ll be the biggest and brightest of the year.
In practice, the differences are fairly minor and likely won’t be visible to the naked eye when compared side by side to other supermoons. A supermoon is only about 7% larger than a regular full moon. According to NASA, the biggest difference is when comparing a supermoon to a micromoon, where a supermoon will be about 14% larger and 30% brighter. So, if you notice that your backyard patio is lit up more than usual, it’s because of the supermoon.
Also due to the moon’s orbit, November will also bring a micro new moon, which means the moon will be as far away from the Earth as it can get — a phenomenon known as apogee. November’s new moon occurs on Nov. 20, but you won’t be able to see it.
