When did the bad harvests in France start during the french revolution?

Answer 1

1787 was not a bad harvest, in fact; but the autumn was very wet, which delayed sowing; the Spring of 1788 was hot, which dried the young shoots, and in July there was a horrific hailstorm over a large area of the country, which completely destroyed cereals and grapes. After that the winter of 1788-9 was exceptionally hard.

Answer 2

The bad harvests rolled around in the 1780s due to poor weather conditions!
