Weather by the Moon

See the below Weather by the Moon calendar showing what sort of weather will probably follow the Moon's entrance into any of its quarters.

The calendar below is derived from "A Table Foretelling the Weather Through All the Lunations of Each Year, or Forever," which first appeared in The Old Farmer's Almanac in 1834.

It is the result of many years of actual observation and shows what sort of weather will probably follow the Moon's entrance into any of its quarters. For example, the day that the Moon enters its first quarter may be stormy. 

Note: This table is shared for its historical interest. It was created by Dr. Herschell for the Boston Courier so it may have regional bias. In addition, it was created 175 years ago. It is not meant to be compared with our annual long-range weather forecasts for The Old Farmer's Almanac; we rely far more on our projections of solar activity.

All the same, it raises the question: Does the Moon affect weather? Is this folklore? Or, is there a relationship between weather and the Moon and Moon phases?

To read this chart, you'll need to reference the year's Moon phases. See our customized Moon Phase Calendar.
