December 5, 2025, brings the final Supermoon of the year in Gemini, appearing largest for Southern Hemisphere viewers due to its summer timing and optical effects near the horizon, while energizing communication and social vibes post-Mercury Retrograde. (148 characters)
On Friday, December 5, 2025, the last Full Moon of the year arrives as a Supermoon. It peaks at exactly 10:14 am AEDT, making it visible as full on the previous Thursday evening and Friday night. This event stands out as the biggest Supermoon of 2025, thanks to its closeness to the summer solstice.
For the optimal sight, gaze toward the horizon on Friday evening. Southern Hemisphere observers enjoy a prime view since the Moon hangs lower in summer skies, creating an illusion of greater size. Northern viewers might see a similar effect with the June Full Moon instead.
Known as the Cold Moon or Long Night Moon from Native American, colonial American, and European traditions, it marks the Northern Hemisphere's winter start—though it feels mismatched for those in Southern summer warmth. In Gemini, an air sign, this Supermoon boosts social interactions and communication, helping shake off lingering Mercury Retrograde confusion.
Gemini's adaptable energy brings curiosity and easy chatter, ideal for busy end-of-year schedules. Emotions may intensify, but the sign adds lightness, turning social duties into enjoyable connections. With Sagittarius influences from Mars and Venus, optimism and playfulness enhance the mood, promoting clarity over chaos.
