From January to April every year, Japan Weather Association (JWA) announces the cherry blossom forecast for various locations around Japan. The forecast of the dates when cherry blossoms will bloom is released on the Cherry Blossom Forecast page of the dedicated weather forecast website “tenki.jp.”

Data Utilized for Forecasting Cherry Blossoms

  • Temperature observation data from the previous autumn to the forecast date
  • Temperature forecast data from the forecast date to the blooming period (from Japan Weather Association’s point forecasts and long-term forecasts)

Methods and Characteristics of the JWA’s Cherry Blossom Forecast

We use our proprietary forecasting model that focuses on the temperature trends from autumn onwards, which significantly influences the growth process of the cherry blossom buds. Our forecasts are based on accurate observation data from sample trees at local meteorological observatories and cooperating agencies, emphasizing meteorological principles.

Glossary of Cherry Blossom Forecast Terms

What are the Criteria for the Blooming Dates?

The criteria are the same as those used by the Japan Meteorological Agency. The blooming date is defined as the first day when five to six or more flowers have opened on the designated observation tree (i.e. sample tree.)

What Does “Normal” Mean?

“Normal” refers to the average value over the past 30 years. Currently, the average for the period from 1991 to 2020 is used.

  • Much earlier: 7 or more days earlier than normal
  • Earlier: 3 to 6 days earlier than normal
  • Average: within two days of the normal date

FAQ

Q. What are the criteria for the blooming and full bloom dates?

A. The criteria are the same as those used by the Japan Meteorological Agency. The blooming date is defined as the first day when five to six or more flowers have opened on the designated observation tree (i.e. sample tree), and the full bloom date is the first day when more than 80% of the buds have opened on the sample trees.

Q. How many locations are expected?

A. Forecasts are announced for 53 locations in January and February, and for 84 locations nationwide from March onward. The forecast locations consist of 53 sample trees observed by local meteorological observatories and 31 additional locations where observation data are obtained from cooperating organizations such as municipalities / local governments and parks.

Q. What are the methods and characteristics of the Japan Weather Association’s cherry blossom forecast?

A. We use our proprietary forecasting model that focuses on the temperature trends from autumn onwards, which significantly influence the growth process of the cherry blossom buds. Our forecasts are based on accurate observation data from sample trees at local meteorological observatories and cooperating agencies, emphasizing meteorological principles. Japan Weather Association has been conducting cherry blossom forecasts since 2007, making this year the 20th year of our endeavour.

Q. What data are utilized for forecasting cherry blossoms?

A. The following data are used.

  • Temperature observation data from the previous autumn to the forecast date
  • Temperature forecast data from the forecast date to the blooming period (from Japan Weather Association’s point forecasts and long-term forecasts).

The temperature from the previous autumn to spring significantly influences the cherry blossoming period. Cherry buds form during the previous summer and then enter dormancy3. Exposure to a certain period of low temperatures during winter breaks this dormancy, and the buds grow and bloom with rising temperatures. It is believed that higher temperatures promote faster bud growth and earlier blooming.

3 Breaking dormancy: Flower buds that formed in the previous summer and entered dormancy awaken when exposed to low temperatures for a certain period during the winter.
