Eighteen Hundred and Froze To Death. 1816 – The year that had no summer.
On April 5, 1815, just before sunset, the Mt. Tambora volcano on the Indonesian island of Sumbawa erupted.
The massive load of sulphate gases and debris the mountain shot 43 km into the stratosphere blocked sunlight and distorted weather patterns for three years, dropping temperatures between two and three degrees Celsius, shortening growing seasons and devastating harvests worldwide, especially in 1816.
In New England six inches of snow fell in June and every month of the year had a hard frost.
Temperatures dropped to as low as 40 degrees in July and August as far south as Connecticut.
