If you’ve been wondering what’s happening with the moon tonight, you’re in for something special. The final supermoon of 2025 — also called the Cold Moon — is glowing beautifully over the United States, and it’s one of the brightest lunar moments of the year.
As someone who watches sky events regularly (yes, I’m that friend who sends moon photos at midnight!), I can tell you this one is worth stepping outside for.
Let’s break it down in simple, friendly language so you know exactly what’s happening, why it’s special, and when to look up.
What’s Happening With the Moon Tonight?
On December 4 (US) and early December 5 (India), the final supermoon of 2025 reached its peak brightness.
This glow comes from the Moon being slightly closer to Earth than usual — around 221,965 miles away — which makes it look bigger, clearer, and noticeably brighter.
Even if you missed the exact peak, don’t worry.
The moon remains bright for a couple of nights, so you still have time to enjoy it.
Why This Supermoon Is Special
This Cold Moon is the third and last supermoon of 2025, making it the grand finale of the year’s lunar show.
Because the Moon is closer to Earth:
- It appears up to 14% larger
- It can shine about 30% brighter
- It feels more dramatic when rising over the horizon
One thing I personally love is the moon illusion — when the moon first rises, it looks huge, almost like a glowing planet. It’s all an optical trick, but trust me, it’s stunning and perfect for photography.
Best Time to Watch the Moon Tonight
Even though the peak was earlier, the moon still looks beautiful tonight. Here’s how the timings worked:
Moonrise in the US (Dec. 4)
- New York: Around 4:56 pm EST
- Los Angeles: Around 5:27 pm PST
Where the Moon Looks Brightest
The U.S. Naval Observatory said the moon reached its highest and brightest point around midnight local time.
If you’re stepping outside tonight, you’ll still get a big, bright view — especially if the weather is clear.
Why December’s Full Moon Is Called the “Cold Moon”
Every full moon has a name, and December’s is one of my favorites.
The name Cold Moon comes from Native American traditions, especially the Mohawk people, who associated this moon with the arrival of harsh winter cold.
Some tribes, like the Mohicans, called it the Long Night Moon, a nod to December’s long, dark winter nights.
These names weren’t just poetic — they were practical markers for seasonal changes.
What Exactly Is a Supermoon? (Simple Explanation)
A supermoon happens when:
- The moon is full
- The moon is at its closest point to Earth (called perigee)
When these two moments line up, the result is:
- A larger-looking moon
- A brighter glow
- A more dramatic rise on the horizon
NASA says the difference can be up to 14% in size and 30% in brightness — and yes, your eyes can really notice it.
How the Moon Tonight Looked in India
If you’re reading this from India, the event happened before dawn on December 5.
Even though the timing was different from the US, people in India also saw a bright, crisp moon overhead thanks to the clear winter skies.
The moon will continue to appear fuller and bright through the evening of December 6, so there’s still time to catch the glow.
Real-Life Tip: How to Get the Best View Tonight
From my own skywatching experience, here are a few simple tips:
- Look east when the moon is just rising — that’s when it feels biggest.
- Try to find a spot with fewer buildings or trees blocking the sky.
- Use your phone’s night mode for surprisingly good moon photos.
- Step out 15 minutes before moonrise to catch the glowing horizon.
Even if you’re not a “sky person,” this supermoon is something you’ll appreciate.
If You Missed It — Don’t Worry
Sky events always come with a little FOMO, but the good news is:
Three new supermoons are coming in 2026.
So even if clouds blocked your view or you fell asleep early (we’ve all been there!), you’ll get more chances next year.
Final Thoughts: Step Outside and See the Moon Tonight
The moon tonight is not just another full moon — it’s the last supermoon of the year, and it brings a quiet, magical ending to 2025’s sky events.
Whether you enjoy astronomy, photography, or just peaceful moments outdoors, this is the perfect excuse to pause and look up.
Take a minute, breathe in the cold air, and enjoy the glow.
