Mawsynram, Meghalaya
June–September monsoon total
Modelled demonstration series · not observed data
A dry year in the wettest place on Earth still leaves more rain than most cities see in a decade, which is exactly why it is easy to miss. Terraced agriculture and spring-fed water supply here are calibrated to the usual deluge. A shortfall of this size is a genuine water problem in a place nobody thinks of as dry.
75 years, modelled
Same reading, two normals
| Normal | Mean | σ | Pct | Return |
|---|---|---|---|---|
| 1951–1980 | 9200 mm | −1.80σ | 4th | 1 in 28 years |
| 1991–2020 | 9267 mm | −1.78σ | 4th | 1 in 26 years |
Today would rank 2 of 76 for lowest value in the modelled series. Nothing about the reading changes between rows — only the yardstick.
The season here
The Khasi Hills lift saturated Bay of Bengal air straight up; the monsoon here delivers more rain than almost anywhere on Earth.
Where this series comes from
MODELLED SERIES — not observed. Parameters set from published Mawsynram/Cherrapunji monsoon-total climatology; the series uses a lognormal transform because seasonal rainfall totals are right-skewed. The 75 annual values are synthesised by the seeded generator.
Every number on this page comes from a modelled series: 75 annual values synthesised by a seeded generator from published climatological parameters for Mawsynram, Meghalaya. It shows how anomaly reasoning works. It is not a measurement and must not be cited as one.
