March winds and April showers Bring forth May flowers.

The proverb links the wind and rain of early spring with the flowers that appear later. What feels unpleasant at the time can also be part of a process of growth.

Figuratively, a difficult stretch may help make a later benefit possible. The saying encourages patience when the results of effort or discomfort are not yet visible.

Use it to encourage someone working through a difficult period, especially when there is reason to hope that present effort or discomfort will lead to something good. It need not imply that hardship always brings a reward.
