Moon in Porto Alegre Today — Waning Gibbous

Tonight the moon in Porto Alegre is in the Waning Gibbous phase. It is 84% illuminated and 18.7 days into the current lunar cycle. Moon phases are the same worldwide — only the exact local clock time of moonrise and moonset differs by location.

The next full moon occurs on 1 de mayo de 2026, which is 26 days from today. During a full moon the Moon is 100% illuminated as seen from Earth.

The next new moon occurs on 16 de abril de 2026, in 11 days. The new moon marks the start of a fresh 29.5-day lunar cycle and is not visible in the night sky.

A lunar (synodic) cycle lasts approximately 29 days, 12 hours, 44 minutes — or 29.53 days. It runs from one new moon to the next, passing through 8 distinct phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.

No — the moon phase (the fraction of the Moon illuminated) is the same everywhere on Earth at any given moment. However, moonrise and moonset times, as well as the moon's altitude in the sky, vary by location. The moon also appears upside-down in the Southern Hemisphere compared to the Northern Hemisphere.
