How the Full Moon Impacts Nature

The Moon, in addition to its light at night, has a physical impact of the Moon on the Earth and Nature. Moons’ gravitational pull on the Earth causes the tides to rise and fall, with the most substantial effect at the peak of the full moon.

Blue Moon

In 2100 there will be a seasonal blue moon on Thursday, August 19 because Summer will have an extra full moon.

There are two definitions of blue moons. The most common, and the one you likely know, is when two full moons occur in the same month. The second full moon is typically called a blue moon.

The second definition relates to having an extra full moon on the calendar during a season. When a season has four full moons, the third full moon is also called a blue moon or a seasonal blue moon.

Harvest Moon

The Harvest Moon will be on Saturday, September 18. The September Full Moon will be the ninth full moon of the year and the full moon in Pisces. The Full Harvest Moon will be the last full moon before the Autumnal Equinox, making it the last full moon of Summer.

Depending on the year, the Full Harvest Moon may either be part of the Summer or Autumn season. In 2100 it will be part of Summer.
