KMA station observations
Daily statistics from a KMA agricultural station, framed against a climate normal. A normal is a 30-year average, and which 30 years you pick changes the answer — so every departure on this page names its baseline.
Observed 2026-09-16 · Chuncheon, Gangwon · KMA station 101
The most recent complete day. A day in progress is not a daily statistic, so today is never shown.
Daily statistics from 농업 일통계 (arcltr_sfc_day), each against the normal for the same calendar day.
Daily mean temperature against the 1991–2020 normal for each calendar day
How much fell, and how fast. These are different events agronomically and are never combined here.
The agronomic extras from ASOS 일자료 (kma_sfcdd) for the same day — evaporation as an irrigation-demand proxy, the grass-surface minimum that frost actually forms on, sunshine and fog.
The 2nd warmest 16 September at this station of the 6 years compared.
Years compared: 2021, 2022, 2023, 2024, 2025, 2026. The count is the years KMA actually returned with a non-null maximum, not the years requested.
14 of the 14 days requested had both an observation and a normal. The vertical axis is symmetric around a true zero and is never truncated — a cropped baseline makes an ordinary departure look extreme.

No rain recorded.
17 mm of rain over a day soaks in. 17 mm in one hour runs off, caps the soil and takes topsoil with it. Only the daily total has a published normal — peak-intensity figures are shown on their own rather than compared to a daily total, which would be arithmetic on two different quantities.
