Daily temperatures are accumulated from 1 February using the rules Japanese forecasters really use:
the 400℃ rule daily mean temperatures summed to 400℃, and the 600℃ rule
daily highs summed to 600℃ — then we average both results
Maples start turning when daily lows drop below ~8℃ and speed up below 5℃
We accumulate that value max(0, 12℃ − lowest temperature) from 1 August
A year that turns cold early really does redden leaves early
The 400/600℃ rules were built for Tokyo; applied straight to Hokkaido they go wrong So we run the model on each spot’s “normal weather year” first, then shift the result to match the norm JMA 1991–2020 for that spot, before applying it to this year’s real weather
Daily temperatures from Open-Meteo (ERA5 observations + 16-day forecast) Dates beyond that use the past 10 -year average for that spot The “confidence” value shows what percentage uses real weather
⚠️ These are estimates, not official announcements — the Japan Meteorological Agency and forecast companies (tenki.jp, Weathernews, 日本気象) offer no free sakura/autumn-leaf forecast API so the numbers here are computed from temperature and can be off by ±3–7 days especially in years with wild swings before bloom.
