Andhra Pradesh Records Driest Monsoon in 13 Years, Rainfall Deficit Reaches 29%
Andhra Pradesh has recorded its driest southwest monsoon in 13 years, with rainfall during the June to September 2026 season falling 29% below normal. The deficit has increased concerns over Kharif crops, groundwater reserves, reservoir storage and water availability in several parts of the state.
Andhra Pradesh Monsoon 2026: What Happened?
Andhra Pradesh ended the 2026 southwest monsoon season with a major rainfall shortage. The state received approximately 368.1 mm of rainfall between June and September, compared with the normal seasonal rainfall of 521.6 mm.
This represents a 29% deficit and makes 2026 the driest southwest monsoon recorded in Andhra Pradesh in 13 years. The rainfall shortage was not uniform across the state. Some coastal areas performed comparatively better, while districts across Rayalaseema recorded significant deficits.
The weak monsoon has become a major concern for agriculture because a large number of farmers depend on timely rainfall for Kharif cultivation. Longer dry spells have also increased dependence on groundwater and irrigation sources.
Why Was Andhra Pradeshs Monsoon So Dry?
The deficient monsoon has been largely associated with El Niño conditions during 2026. El Niño involves abnormal warming of surface waters in the equatorial Pacific Ocean and can influence atmospheric circulation and monsoon rainfall over India.
Andhra Pradesh has experienced deficient rainfall in several previous El Niño years, although the intensity has varied. The 2026 deficit of 29% is substantially larger than the deficits recorded in some recent El Niño years.
El Niño Years After State Bifurcation
| Year | Rainfall Departure |
|---|---|
| 2015 | 7.4% above normal |
| 2018 | 10% below normal |
| 2023 | 13% below normal |
| 2026 | 29% below normal |
Rainfall Deficit Across Different Regions
Rainfall distribution varied considerably across Andhra Pradesh during the 2026 monsoon. Coastal districts generally performed better than many areas of Rayalaseema, while the southern and interior parts of the state faced greater rainfall stress.
Coastal Andhra
Some coastal districts recorded normal or above-normal rainfall, although conditions varied locally.
Rayalaseema
All districts in the region recorded significant rainfall deficits during the monsoon season.
Southern Areas
Persistent dry conditions increased pressure on agriculture and water resources.
Impact on Kharif Agriculture
Poor rainfall during July and August delayed sowing operations in several areas and affected Kharif crops. Pulses and coarse grains were among the crops reported to have faced pressure because of inadequate and irregular rainfall.
Rain-fed farming areas are particularly vulnerable because they have limited access to alternative irrigation sources. Where rainfall was insufficient during crop establishment and growth stages, farmers had to depend more heavily on groundwater or other irrigation arrangements.
- Delayed sowing in rainfall-deficient areas.
- Lower soil moisture during important crop-growth stages.
- Higher dependence on groundwater and irrigation.
- Increased cultivation pressure for rain-fed farmers.
- Potential impact on Kharif crop productivity.
Groundwater Stress Is Another Major Concern
A prolonged rainfall deficit can affect groundwater recharge and increase dependence on borewells. Farmers and households may use groundwater more frequently when surface-water sources and rainfall are insufficient.
This creates a second layer of risk because higher extraction during a dry period can place additional pressure on already stressed groundwater reserves. The situation is especially important in areas where agriculture depends heavily on borewell irrigation.
The combination of weak rainfall, delayed recharge and increased irrigation demand could therefore continue to affect water availability even after the monsoon season has ended.
Reservoir and Drinking Water Concerns
Lower rainfall also means lower inflows into rivers and reservoirs. This can affect irrigation releases, drinking-water planning and the availability of stored water for the coming months.
Officials and experts have expressed concern that existing reservoir, river and groundwater resources may face pressure if rainfall remains deficient. Water management will therefore remain important during the post-monsoon and Rabi periods.
Andhra Pradesh Rainfall 2026: Key Numbers
| Indicator | 2026 Status |
|---|---|
| Monsoon period | June to September 2026 |
| Actual rainfall | 368.1 mm |
| Normal rainfall | 521.6 mm |
| Rainfall deficit | 29% |
| Monsoon comparison | Driest in 13 years |
Government Response and Agriculture Planning
The rainfall shortage has increased the importance of crop diversification, water conservation, crop insurance and contingency planning. Authorities have been working on agricultural advisories and measures aimed at reducing the impact of the deficient monsoon on farmers.
In rainfall-deficient areas, farmers are being encouraged to consider crops with lower water requirements where local conditions make them suitable. Such measures can help reduce the risk of crop failure when irrigation water is limited.
Andhra Pradesh has also declared drought conditions in 388 mandals across 21 districts for Kharif 2026, underlining the seriousness of the rainfall shortage in affected areas.
Could the Water Stress Continue Into 2027?
The effects of a weak monsoon can continue beyond the end of the rainy season. Reservoir storage, groundwater recharge and agricultural water demand all influence the availability of water during the following months.
Weather experts have warned that El Niño conditions could remain influential toward the end of 2026, with possible effects extending into 2027. However, the actual water situation will depend on subsequent rainfall, reservoir inflows, groundwater recharge and water-management decisions.
This means the 2026 monsoon deficit is not only a seasonal agriculture concern. It could also become a wider water-security issue if recovery rainfall remains insufficient.
What Should Farmers Watch Next?
- Post-monsoon rainfall forecasts and local weather advisories.
- Reservoir storage and irrigation-water availability.
- Groundwater levels in rainfall-deficient districts.
- Government crop advisories and contingency plans.
- Crop insurance and eligible drought-relief measures.
- Water requirements for the Rabi agricultural season.
Key Takeaways
Andhra Pradesh Rainfall Deficit 2026 FAQs
Why is 2026 being called Andhra Pradeshs driest monsoon in 13 years?
Andhra Pradesh received around 29% less rainfall than normal during the June to September southwest monsoon season, making 2026 the driest monsoon in the state in 13 years.
How much rainfall did Andhra Pradesh receive in the 2026 monsoon?
The state received approximately 368.1 mm of rainfall compared with the normal seasonal rainfall of 521.6 mm.
What was the main reason behind the rainfall deficit?
The deficient monsoon was largely associated with prevailing El Niño conditions, although rainfall is influenced by multiple atmospheric and oceanic factors.
Which parts of Andhra Pradesh were most affected?
Rayalaseema experienced significant rainfall deficits, while rainfall conditions varied across coastal Andhra districts.
How can the rainfall deficit affect farmers?
Poor and irregular rainfall can delay sowing, reduce soil moisture, increase irrigation dependence and affect Kharif crop productivity, especially in rain-fed farming areas.
Has drought been declared in Andhra Pradesh?
Yes. Drought conditions have been declared in 388 mandals across 21 districts for Kharif 2026, including 283 severely affected and 105 moderately affected mandals.
Conclusion
Andhra Pradeshs 2026 southwest monsoon ended with a 29% rainfall deficit, making it the driest monsoon in the state in 13 years. The shortage has affected agricultural planning and increased pressure on groundwater, reservoirs and other water resources.
With drought already declared in hundreds of mandals, the focus now shifts to water conservation, farmer support, reservoir management and preparation for the next agricultural season. Post-monsoon rainfall and groundwater recharge will be particularly important in determining the states water outlook for the coming months.
