Peak bloom is defined when 70 percent of the cherry tree’s buds bloom.
The blossoms can remain in bloom for up to a week in favorable weather, namely light wind and no precipitation. Petals fall off faster in rain, snow, frost, unusually warm weather and/or strong winds.
This week’s forecast promises perfect blossom-watching conditions through Tuesday with warm temperatures and light winds, but Wednesday brings rain. While the rain may remove some petals, it should still be fine on Thursday and Friday. Blossoms will likely peak over the weekend amid windy and cooler conditions.
Reflecting a trend toward rising temperatures in late winter and early spring, average peak blooms have advanced five days since the 1920s and 1930s, from about April 4 to March 31.
Five of the top 10 earliest peak bloom dates have occurred since 1990. Last year’s peak bloom date of March 28 was equal to the 19th earliest ever recorded. In 2020, the March 20 peak bloom was the third earliest with four other years. The past three years have seen peak blooms earlier than normal.
