I tracked a week there last April and the cherry blossoms aligned perfectly with 16°C and 8 sunshine hours. The numbers say avoid July's monsoon (300mm+ of rain) and August's heat. September-October is the statistical sweet spot: 18°C, 40mm rain, UV dropping to 5. December-February has its own appeal if you can handle -10°C with wind chill.
