On July 18, 2026, the Moon will be in the new phase, showing 24% visibility. The National Institute of Meteorology (Inmet) has made available the complete calendar of lunar phases for the month.
Lunar Cycle in July 2026
The lunar phases in July 2026 began on the 7th with the Waning Moon, recorded at 4:30 PM Brasília time. Subsequently, the New Moon occurred on the 14th at 6:45 AM. The Waxing Moon was observed on the 21st at 8:05 AM, culminating with the Full Moon on the 29th at 11:37 AM.
Understanding the Lunar Cycle
A lunar cycle, also known as lunation, is the time interval between two new moons and has an average duration of 29.5 days. During this period, the Moon passes through four main phases: new, waxing, full, and waning, with each phase lasting approximately seven days. In addition to these main phases, there are so-called 'interphases', such as the first quarter and the gibbous waxing (between new and full), and the gibbous waning and the last quarter (between full and waning).
Details of Each Lunar Phase
In the New Moon phase, the satellite is positioned between the Earth and the Sun. Consequently, the illuminated side faces the Sun, while the dark side faces us, which prevents its visibility in the night sky. This phase signals the beginning of a new lunar cycle, associated with renewal and new opportunities.
After the New Moon, the Waxing phase appears. Slowly, a small illuminated area begins to appear in the sky, progressively increasing each night. Initially, only a thin arc of light is observed, but this illuminated portion grows until it reaches half of the Moon, a moment called First Quarter. This phase represents development, growth, and the building of new paths.
The Full Moon occurs when the Earth is located between the Sun and the Moon. This allows the entire lunar face facing the Earth to receive light, making it completely visible and bright in the firmament. This is the period of maximum luminous intensity, coinciding with the Moon rising on the horizon at the exact moment of sunset. The Full Moon is linked to fullness, the peak of processes, and energy at its highest point.
Finally, after the Full Moon, the lunar luminosity begins to gradually decrease. Each night, a smaller portion of its illuminated surface becomes visible. When half of the Moon is visible, the Last Quarter occurs, which is the opposite of the First Quarter. The Moon continues to lose brightness until it returns to the New Moon, thus restarting the cycle. The Waning phase symbolizes reflection, closure, and preparation for subsequent beginnings.
