Get ready, South Africa! The final supermoon of 2025, known as the Cold Moon, is set to grace our skies this week. This celestial event promises to be a breathtaking sight, appearing larger and brighter than usual. It's the third supermoon of the year and the last one until early 2026, making it an event you won't want to miss!
What Makes it a Supermoon?
A supermoon occurs when a full moon coincides with the moon's closest approach to Earth in its orbit, a point called the perigee. Because the moon's orbit is elliptical, its distance from Earth varies. When a full moon occurs near the perigee, it appears significantly larger and brighter. NASA notes that supermoons can appear up to 30% brighter and 14% bigger than the smallest full moon of the year!
Why is it Called the Cold Moon?
The name "Cold Moon" comes from the Northern Hemisphere, where December marks the start of winter. It's a fitting name, as the full moon occurs during a time of year associated with cold temperatures and long nights. It's also sometimes called the Long Night Moon, as the longest night of the year falls in December.
How to View the Cold Supermoon in South Africa
To get the best view of the Cold Supermoon, find a location away from city lights. The darker the sky, the more spectacular the moon will appear. Look towards the north-eastern skies after sunset. While the exact rise time will vary depending on your location, the moon will generally be visible throughout the night.
Tidal Effects
Supermoons can also influence tides. The increased gravitational pull of the moon during its closest approach to Earth can result in higher-than-usual tides, sometimes referred to as king tides. Be mindful of coastal areas during this time.
Don't miss your chance to witness this stunning celestial event! The Cold Supermoon of 2025 is a perfect opportunity to appreciate the beauty of the night sky.
