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 date varies year by year.

Peak Bloom predictions 2015Sometimes 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.

We are currently predicting peak bloom 2015 will be around May 7-9th.

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.
