Supermoon to Illuminate Sky Monday Night: What to Expect

The upcoming supermoon on Monday night promises to be a spectacular sight for observers in Quebec. This will be the largest and most brilliant full moon of 2025 thus far. A supermoon occurs when the moon is at its closest point to Earth, appearing up to 14% larger and 30% brighter than usual. This phenomenon happens because the moon’s orbit around Earth is elliptical, leading to varying distances throughout the year.
What is a Supermoon?
A supermoon can be defined as a full moon that comes within 90% of its nearest position to Earth. The upcoming event will also be known as the “Harvest Moon.” This title is given to the full moon closest to the autumn equinox, which took place on September 22 this year. Historically, this full moon provided additional light for farmers during the harvest season, allowing them to work longer hours into the night.
Future Supermoons in 2025
This supermoon marks the first occurrence in nearly a year, with the last one having taken place in November 2024. It will not be the only supermoon of 2025; two more are scheduled for November 5 and December 4.
Weather Expectations
Weather forecasts from Environment Canada indicate that some cloud cover is expected across the province on Monday night, with possible showers in the northern regions. However, astrology enthusiasts may still have a chance to witness the supermoon, as clouds are likely to roll in later in the evening, providing an opportunity for viewing.
