## What is HareBiyori?

What are the odds it'll be sunny on your date?

HareBiyori isn't a forecast. It uses 30 years of NASA satellite climate data to show the statistical likelihood of a clear, sunny day for any calendar date and location worldwide. Pick the date with history on your side.

WHO IT'S FOR
- Planning a wedding, engagement shoot, or photo session
- Choosing the best time to travel somewhere sunny
- Scheduling camping, hiking, sports days, or outdoor events
- Anyone who loves real climate data

KEY FEATURES
Daily weather statistics — For any date, see the sunny-day probability, the weather mix (sunny / cloudy / rainy), average temperature, and average rainfall at a glance.

Monthly calendar — View a whole month of climate trends in a calendar, so you can spot the sunniest and rainiest days visually.

Monthly rankings — Rank every month by sunny-day rate, rainfall, and rainy-day rate to instantly find the best month to go.

30-year day detail — For each date, browse year-by-year records across the past 30 years, including temperature and rainfall trends.

Worldwide coverage — Around 500 locations across the globe, so you can check the climate of your travel destination before you book.

ABOUT THE DATA
Climate data comes from NASA POWER (Prediction Of Worldwide Energy Resources), based on satellite observations.
