Mizoram Weather Forecast & Climate Summary
Mizoram is entirely hill country — a series of steep, roughly parallel north-south ridges and valleys with no significant plains — which combined with heavy monsoon rainfall makes it one of the most landslide-exposed states in India.

Geography & Seasonal Cycle
The state consists of a sequence of parallel hill ranges (part of the Lushai Hills and the broader Indo-Myanmar border range system) separated by narrow valleys, generally running north-south and rising in elevation from west to east. There are no significant flat plains anywhere in the state.
The monsoon (roughly May/June-September) brings heavy, sustained orographic rainfall to the windward western-facing slopes as moisture moves in from the Bay of Bengal. Winter is mild and comparatively dry; pre-monsoon brings periodic thunderstorms.
Weather Systems by Season
Mizoram's parallel hill ranges catch substantial monsoon rainfall on their western, windward-facing slopes as Bay of Bengal moisture moves inland.
The combination of young, geologically less stable fold-mountain terrain and heavy sustained monsoon rainfall makes landslides a routine, high-impact hazard, frequently cutting off roads between hill towns.
Narrow valley streams can rise very quickly during intense rain, posing a flash-flood risk to settlements along them.

Seasonal Weather Data
The table below is a state-wide average across Mizoram's 11 districts, built from IMD's real 1991-2020 gridded rainfall/temperature normals and 1951-2025 daily archives (not a forecast). Use the district climatology tool linked below for any single district's own figures.
| Season | Rainfall (mm) | Rain days | Mean Max / Min (°C) | Typical Hottest / Coldest (°C) | Sky (Sunny·Partly·Overcast days) |
|---|---|---|---|---|---|
| Winter Jan–Feb | 20.9 | 5.8 | 23.1 / 12.0 | 26.2 / 10.1 | 35.4·23.6·0.0 |
| Pre-Monsoon (Summer) Mar–May | 321.4 | 41.2 | 28.9 / 19.2 | 30.5 / 15.0 | 20.3·69.5·2.3 |
| Monsoon (SW) Jun–Sep | 997.5 | 95.1 | 28.2 / 21.9 | 29.1 / 21.2 | 0.0·69.4·52.6 |
| Post-Monsoon Oct–Dec | 145.4 | 18.6 | 25.2 / 16.3 | 29.0 / 11.0 | 25.5·64.8·1.7 |
State figures are a simple average across 11 member districts (IMD Pune 1991–2020 normal; day-count and sky figures from real 1951–2025 daily archives — see District Climatology tool for any single district's own numbers, which can differ substantially from this state average).
Recorded Extremes (IMD 1951–2025 Gridded Data)
- Highest maximum temperature recorded (Mamit): 36.2°C — 1 May 1960
- Lowest minimum temperature recorded (Mamit): 4.5°C — 13 Jan 1989
- Highest 24-hour rainfall recorded (Lunglei): 630 mm — 28 May 1990
- Highest monthly rainfall recorded (Saiha): 1495 mm — Aug 2017
Computed directly from the real IMD 1951–2025 daily gridded archive — not a forecast, and not the same as a single-station record. IMD's gridded temperature is 1°×1° (~111 km/cell) and rainfall is 0.25°×0.25° (~25 km/cell); both are spatial analyses of many station observations; a famous single-station record (e.g. a specific town's all-time hottest day) will typically read higher than the grid-cell value shown here, since one station reading isn't smoothed over a ~25–111 km box. "Place" is the nearest district to the grid cell where the extreme occurred, not necessarily the exact spot.
Risk Profile
Monsoon (May/Jun-Sep). Mizoram's young, steep hill terrain combined with heavy sustained rainfall makes it one of the most landslide-exposed states in India, with frequent road disruption between hill towns.
Monsoon (May/Jun-Sep). Narrow valley streams can rise rapidly during intense rain, threatening settlements along them.
Monsoon, compounded by land use. Traditional jhum (shifting) cultivation on hill slopes interacts with heavy monsoon rainfall to increase erosion risk, a recognised regional land-management concern.
Mizoram Weather Highlights
- Mizoram has no significant flat plains anywhere in the state — its entire geography is a sequence of steep, parallel hill ranges and valleys.
- The combination of young, less stable fold-mountain geology and heavy monsoon rainfall makes it one of India's most landslide-exposed states, with road connectivity between hill towns routinely disrupted each monsoon.
- Traditional jhum (shifting) cultivation practices on hill slopes are a recognised factor in the region's erosion sensitivity, interacting with the terrain's inherent landslide risk.
