October’s full moon shall be a brilliant harvest moon, and can rise Monday, Oct. 6, bringing extra night mild as we get nearer to the top of daylight saving time.

The tremendous harvest moon is the primary of 4 supermoons that can seem between October and January 2026. It will rise barely nearer to the Earth, making it seem bigger and with an orange haze.

The moon’s greater and brighter look can even final for a number of days, as it is going to rise across the identical time every evening, in keeping with the Old Farmer’s Almanac.

Here’s what to learn about October’s 2025 tremendous harvest moon.

When is the October 2025 tremendous harvest moon?

The tremendous harvest moon will rise at roughly 6:22 p.m. on Monday, Oct. 6.

What is a harvest moon?

A “harvest moon” is the primary full moon to rise closest to the autumn equinox, which was on Sept. 22.

The full moon known as the harvest moon as a result of it happens across the busiest time of harvest season. Farmers typically work late into fall’s darker night hours, however when the total moon rises, it lends them just a little extra mild to complete.

What is a supermoon?

A supermoon happens when the moon’s orbit brings it nearer to the Earth, giving it a bigger and brighter look.

“The bigger-than-usual size of a moon seen near the horizon is a trick your eyes play on you, called ‘the moon illusion,'” stated Jim Todd, OMSI director of area science training. “The illusion is a matter of perception, a trick of the brain, which perceives the moon when seen overhead as (farther) than the moon seen at the horizon.”

Why is the tremendous harvest moon orange?

The moon will seem orange when it first begins to rise because of the bodily impact created by its closeness to the horizon.

“When looking toward the horizon, we are actually looking through a greater thickness of Earth’s atmosphere than when looking directly overhead,” Todd stated. “The atmosphere scatters blue light (the reason the sky looks blue). The thickness of the atmosphere in the direction of a horizon scatters blue light most effectively, but it lets red light pass through. Therefore, a moon near the horizon takes on a yellow, orange or reddish hue.”
