PEAK BLOOM

PEAK BLOOM DATE & BLOOMING PERIOD

The National Park Service defines the peak bloom date as the day on which 70% of the blossoms of Yoshino cherry trees that surround the Tidal Basin are open. The date varies from year to year depending on weather conditions. The blooming period is defined as the time when 20% of the blossoms are open until the petals fall and leaves appear. The blooming period starts several days before the peak bloom date and can last as long as 14 days. However, frost or high temperatures combined with wind or rain can shorten this period. Below you will find a comparative record of past bud development. The date listed is when 70% of the buds have reached each stage.
