Moon Phase Today: A Brilliant Waning Gibbous Over Mexico
As the sun sets on January 4, 2026, a spectacular, nearly full moon will dominate the evening sky over Mexico. Tonight’s lunar display is not just a beautiful sight; it’s a specific phase in the Moon’s monthly journey, rich with astronomical detail. For stargazers, photographers, and the simply curious, understanding the “luna de hoy” provides a direct connection to the rhythms of our solar system.
The Moon is currently in its Waning Gibbous phase, a period of gradual fading after the peak brilliance of the Full Moon. This means over 97% of its Earth-facing side is still bathed in sunlight, making it an incredibly bright and detailed object to observe, even in areas with some light pollution.
Today’s Lunar Snapshot: January 4, 2026
Based on the latest astronomical data, here are the precise details for the Moon’s status today. This information is crucial for planning observations or understanding what you’re seeing in the night sky.
| Metric | Detail for Today |
|---|---|
| Current Phase | Waning Gibbous |
| Illumination | 97% – 99% (Sources vary slightly) |
| Age of Moon | Approximately 15-16 days into its 29.5-day cycle |
| Visibility Trend | Decrescent (Decreasing illumination each night) |
| Key Celestial Neighbor | Close to the bright planet Jupiter this evening |
What Does “Waning Gibbous” Mean?
This phase occurs immediately after the Full Moon. “Waning” means it is shrinking or decreasing in illumination, while “Gibbous” describes its shape—more than half illuminated but not a full circle. You can expect to see this moon rise in the east after sunset, but it is particularly prominent in the early morning hours, shining brightly in the western sky before dawn.
“During this phase the Moon can be seen in the early morning daylight hours on the western horizon,” notes MoonGiant.com, highlighting its perfect positioning for early risers.
How to Observe Tonight’s Moon
With such high illumination, minimal equipment is needed. Your naked eye will reveal the major maria (dark “seas”) and bright highlands. Binoculars will dramatically enhance the view, showing countless craters along the terminator—the line between light and shadow. For the best experience, find a spot with a clear view of the southeastern sky after dusk.
Notable Astronomical Events This Week
The Moon’s journey is part of a broader celestial dance. Its close pass by Jupiter tonight is just one highlight in a week filled with astronomical activity. The following table outlines key events surrounding today’s date, based on the 2026 astronomical calendar.
| Date | Event | Notes |
|---|---|---|
| Jan 4 | Close Approach of Moon & Jupiter | The Waning Gibbous Moon appears very near the bright planet Jupiter in the evening sky. |
| Jan 4 | The Moon at Perigee | The Moon reaches its closest point to Earth in its orbit, making it appear very slightly larger. |
| Jan 7 | Conjunction of Moon & Jupiter | A precise alignment of the Moon and Jupiter in the sky. |
| Jan 11 | Moon at Last Quarter | The next major phase shift, presenting a perfect half-moon. |
The Moon’s Path in Mexico’s Sky
For observers in Mexico City, Guadalajara, Monterrey, and across the country, the Moon’s position will be high and favorable. From a central location, the Moon will be visible looking towards the South-Southeast at a high altitude, ensuring great visibility away from terrestrial obstructions. Its brightness will outshine all but the brightest stars and planets, with Jupiter being its prominent companion.
This Waning Gibbous phase is a reminder of the Moon’s constant motion. Each night, the illuminated portion will shrink slightly as we march toward the Last Quarter Moon on January 11th. It’s a perfect time to start a nightly moon-watching journal.
