The full moon is a phase of the lunar cycle when the sun fully illuminates the side of the satellite visible from Earth. This article covers the date and time of the full moon in July 2025, the astronomical details, and explains why this specific full moon is called the `Deer Moon`.
When the Full Moon Occurs in July 2025
Observing the full moon is a unique experience, whether viewed from a scientific, spiritual, or aesthetic perspective. The peak of the full moon phase, when the sun perfectly illuminates the Earth-facing side, is a specific moment in time.
In July 2025, this moment occurs on July 10, 2025, at 23:37 Moscow time. However, observers are not limited to this single instant. The fully illuminated disc of the moon is visible for several days before and after this peak.
Why the July Full Moon is Called the Deer Moon
The July full moon is commonly known as the `Deer Moon`. This name originates from Native American tribes who associated this full moon with the time when male deer begin to grow their new antlers.
The July full moon is also called the `Thunder Moon` due to the frequent thunderstorms in mid-summer. Indigenous peoples of Alaska refer to it as the `Salmon Moon`, reflecting the seasonal run of salmon. In European cultures, it was historically called the `Hay Moon`, marking the beginning of haymaking season.
Moon Phases in July 2025
Moon`s Sign and Constellation
According to astropsychologist and numerologist Yana Pustovalova, the July full moon is notable not only for occurring at the peak of summer but also because the Moon will be in the sign of Capricorn while appearing against the backdrop of the constellation Sagittarius. This distinction arises because zodiac signs in astrology and astronomical constellations are different, and the Moon`s position in them may not coincide.
How This Full Moon Differs from Others
At the peak moment on July 10, 2025, the Moon will appear low on the horizon, making the Deer Moon look visually larger to observers.
This period also includes a trine between the Moon and Mars. The influence of this aspect is expected to impact various areas of life:
- In the professional sphere: It`s a time for showing initiative, asserting your interests, and promoting new ideas.
- In personal life: It`s a favorable period for strengthening relationships, expressing feelings, and resolving conflicts.
Increased courage, activity, and self-confidence may lead to significant life changes. However, the energy of Mars can also provoke impulsiveness and aggression, so it`s crucial to control emotions and avoid conflicts.
How the Full Moon Will Affect Life and Emotions
The full moon on July 10, 2025, is considered a time for evaluating accomplishments and planning future steps. Emotions during this period may focus on success and achieving goals, potentially facilitating conflict resolution and strengthening relationships. Key influences of the full moon in Capricorn include:
- Strictness,
- Discipline,
- Emotional control,
- Responsibility,
- Career growth.
Astropsychologist and numerologist Pustovalova notes that the “earth energy of Capricorn will make everyone come down to earth, prompting focus on structure, discipline, and rationality.”
Which Zodiac Signs Will Experience the Strongest Effect
The following zodiac signs are expected to feel the strongest effects of this full moon:
- Aries: Energy, breakthrough in affairs;
- Libra: Decisiveness, clarity of goals;
- Pisces: Hard work, a chance for dreams to come true;
- Sagittarius: Career opportunities.
According to the expert, the July full moon will bring new energies to everyone, and even those unprepared for this period will experience its consequences.
What to Do and Not Do on the Day of the Deer Moon
In astrology, the full moon is seen as a time for transformation, taking stock, and completing ongoing tasks. Esoteric practices recommend using this time to declutter spaces and thoughts, prioritize, and make future plans.
On this day, it`s advised to avoid starting new projects or making drastic appearance changes. It`s also important not to succumb to emotions, make impulsive decisions, or shift responsibility.
How to Observe the Deer Moon and What Will Be Visible Nearby
The fully illuminated lunar disc is visible for several days around the peak. For the best viewing experience, find a location with an unobstructed horizon, ideally on high ground away from city lights.
Pustovalova suggests observing from anywhere but recommends a telescope for a better view of the moon`s details. She also mentions the old saying about not looking at the full moon due to its “bewitching energy”.
Those observing the Deer Moon on the evening of July 10th will see the `Summer Triangle`, a combination of three bright stars, appearing above it. Immediately after midnight, Vega, Deneb, and Altair will shine above the moon.
To best observe the night sky, it`s advisable to find locations away from populated areas with minimal light pollution.
Why the Moon May Look Red or Orange
The color of the moon can change from pinkish to orange or deep red due to light refraction through the Earth`s atmosphere. The lower the moon is on the horizon, the more light is scattered, resulting in richer hues. When moonlight passes through dense atmospheric layers, observers see the reddish and orange tones of the moon.
Is There an Influence of the Full Moon on Human Health?
Opinions on whether lunar cycles affect human physical and emotional states vary. From a scientific standpoint, solar activity is known to influence humans, but there is no consensus regarding the influence of moon phases, especially the full moon. While there is evidence of moon phases affecting bees, fish, some birds, and amphibians, researchers disagree on what specifically happens to the human body during a full moon.
When is the Next Deer Moon?
The lunar calendar reflects the cyclical changes in moon phases. In 2026, the Deer Moon will occur at the end of July, on the 29th.
