Climate of Tripura: Rainfall, Temperature & Seasons
The climate of Tripura is humid tropical monsoon, with hot and humid summers, a long rainy season and a comparatively mild, dry winter. Heavy rainfall is one of the defining climatic features of the state.
An IMD study of Agartala and Kailashahar for 1955–2017 found an annual mean rainfall of more than 2,000 mm, with roughly 60% during the monsoon and about 30% during the pre-monsoon season.
Climate of Tripura at a Glance
| Feature | General Pattern |
|---|---|
| Climate type | Humid tropical monsoon |
| Annual rainfall | More than 2,000 mm mean in the IMD Agartala-Kailashahar study |
| Main monsoon | June to September |
| Pre-monsoon | March to May; thunderstorms and substantial rainfall |
| Winter | December to February; cooler and relatively dry |
| Warm period | Pre-monsoon and early monsoon months |
| Main controls | Latitude, monsoon circulation, hill relief and moisture from the Bay of Bengal region |
Factors Controlling Tripura's Climate
- Tropical latitude
- Southwest monsoon
- North-south hill ranges
- Low average elevation compared with Himalayan states
- Proximity to Bangladesh and moist air pathways
- Dense vegetation and local topography
Temperature of Tripura
Lowland Tripura is warm for much of the year. Pre-monsoon months can become hot and humid, with daytime temperatures entering the mid-to-upper 30s °C during hot spells. Winter is mild, although clear nights can become noticeably cool, especially away from dense urban areas.
Rainfall in Tripura
Rainfall is abundant but highly seasonal. The IMD study found that about 60% of annual rainfall falls during the southwest monsoon and about 30% during the pre-monsoon season. This means Tripura receives substantial rain even before June.
Thunderstorms are common during the pre-monsoon period. During the monsoon, prolonged rain can raise rivers rapidly and cause flooding in low-lying valleys.
Seasons of Tripura
Winter: December–February
Cooler, drier weather with lower humidity and pleasant daytime conditions.
Pre-Monsoon / Summer: March–May
Rising temperature, high humidity and frequent thunderstorms. A substantial share of annual rainfall occurs in this period.
Southwest Monsoon: June–September
The wettest season, marked by persistent cloud, heavy rain, river flooding and saturated soils.
Post-Monsoon: October–November
Rainfall decreases and humidity gradually falls, although occasional heavy rain can still occur.
Climate of Agartala
Agartala lies in the western lowlands and experiences warm, humid summers and heavy monsoon rain. Urbanisation can increase local heat and worsen drainage problems during extreme rainfall.
Regional Climatic Variation
Tripura's climatic contrasts are modest compared with Himalayan states, but elevation still matters. Jampui Hills and other uplands are generally cooler than the western plains. Windward slopes may receive enhanced rainfall, while valley exposure affects fog, humidity and temperature.
Climate and Agriculture
Heavy rainfall supports rice, rubber, tea, pineapple, jackfruit and other tropical crops. However, rain-fed dependence makes agriculture vulnerable to dry spells, extreme rainfall and flood damage. See Agriculture of Tripura.
Climate-related Hazards
- River and urban flooding
- Waterlogging
- Landslides in hill areas
- Thunderstorms and lightning
- Soil erosion
- Heat and humidity stress
Climate Change Concerns
Climate change can affect rainfall intensity, seasonal timing, heat extremes, river flow and agricultural reliability. Long-term planning therefore requires both flood management and improved water storage for dry periods.

Frequently Asked Questions
What type of climate does Tripura have?
Tripura has a humid tropical monsoon climate.
How much rainfall does Tripura receive?
An IMD study of Agartala and Kailashahar found annual mean rainfall above 2,000 mm.
When is the rainy season?
The main southwest monsoon season is June to September, with substantial pre-monsoon rain from March to May.
Why is Jampui cooler than Agartala?
Jampui Hills lie at substantially higher elevation, so temperatures are generally lower.
Conclusion
The climate of Tripura is defined by warmth, humidity and abundant monsoon rainfall. This climate supports dense vegetation and productive tropical agriculture but also creates significant flood, erosion and drainage challenges.
