Predicting Peak Bloom

One of the most frequently asked questions in High Park during the early spring is “When will High park’s cherry blossom / Sakura trees bloom?”

Blossoms usually reach peak bloom in late April or early May. As you can see from our Peak Bloom Records, the dates varies year by year.

Temperature vs. Peak Bloom in Cherry Blossoms in High ParkSometimes the winter is harsh and the blossoms are late; when the winter is mild, the blossoms are early. Click on chart to the left to see how temperature and bloom dates correspond.

Based on our Bloom-tracking research, we predict Peak Bloom of 2014 to arrive in and around May 19th.

The blooming period begins when 20% of the cherry blossoms are open and ends when their petals fall. “Peak bloom” starts when at least 70% of the blossoms are open. Once open, flowers last from 4-10 days, depending on the weather conditions.
