Mexico's December 2025 Supermoon Will Dazzle Skies on December 4

A supermoon will light up the sky over Mexico on 4 December 2025. It will be visible to the naked eye across the country if weather conditions allow. The event begins at 5:14 p.m. in Mexico City and peaks around 9 p.m. A supermoon happens when the moon is at its closest point to Earth during a full moon. This makes it appear 14% larger and brighter than a typical full moon.

The phenomenon will also be visible at dawn the next day. Clear skies on 5 December around 5 a.m. will offer another chance to see it. However, light pollution in Mexico City may reduce visibility.

Heavy rain, frequent in 2025, could further obstruct the view on 4 December. If clouds block the sky, live broadcasts will be available online through NASA and UNAM’s official social media accounts. The December 2025 supermoon will be observable without special equipment from anywhere in Mexico. Online streams provide an alternative if rain or poor visibility prevents a clear view. The event offers a rare opportunity to witness a brighter and larger moon.
