Andhra Pradesh Records Driest Monsoon in 13 Years with 29% Rainfall Deficit
Andhra Pradesh has experienced its driest southwest monsoon in 13 years during 2026, with the state receiving 29% less rainfall than normal between June and September. The prolonged rainfall deficit is creating pressure on Kharif agriculture, groundwater resources, reservoirs and drinking-water availability.
Andhra Pradesh Monsoon 2026: A Major Rainfall Deficit
Andhra Pradesh has ended the 2026 southwest monsoon season with a significant rainfall shortage. The state received around 368.1 mm of rainfall between June and September against a normal rainfall of 521.6 mm, resulting in a deficit of approximately 29%.
This makes the 2026 southwest monsoon the driest monsoon recorded in Andhra Pradesh in 13 years. The rainfall shortage has been uneven across the state, with several parts of Rayalaseema experiencing particularly severe deficits while some coastal areas performed comparatively better.
The weak monsoon has become a major concern for agriculture because Kharif cultivation depends heavily on timely and adequate rainfall. The situation is also putting additional pressure on groundwater and available surface-water resources.
Why Was 2026 Such a Dry Monsoon?
One of the major factors associated with the deficient monsoon was the prevailing El Niño condition. El Niño can influence atmospheric circulation over the Indian region and reduce monsoon rainfall in several parts of the country.
The rainfall shortage was particularly visible during important parts of the monsoon season. Dry spells during July and August affected sowing and crop establishment in several agricultural areas.
El Niño and Andhra Pradesh
The 2026 monsoon is among the recent El Niño-affected seasons in Andhra Pradesh. Earlier El Niño years also produced varying levels of rainfall stress, but the 29% deficit recorded in 2026 represents a particularly significant shortfall for the state.
Rainfall Situation Across Andhra Pradesh
Rainfall distribution has been highly uneven. Coastal districts generally performed better than several districts in the southern and Rayalaseema regions, while the latter experienced much larger deficits.
| Area | Rainfall Situation | Major Concern |
|---|---|---|
| Coastal Andhra | Mixed rainfall performance | Localised agricultural and water stress |
| Rayalaseema | Significant rainfall deficit | Crops, groundwater and reservoirs |
| Southern Andhra | Below-normal rainfall | Kharif agriculture and water availability |
| Statewide | 29% below normal | Agriculture and long-term water security |
Impact on Kharif Agriculture
The rainfall deficit has directly affected agricultural operations in several parts of Andhra Pradesh. Farmers reported delayed sowing and difficulties in establishing Kharif crops during periods of prolonged dryness.
Pulses and coarse grains have been among the crops affected by inadequate and irregular rainfall. Lower rainfall also increases dependence on groundwater and irrigation, raising cultivation costs and putting pressure on available water resources.
- Delayed sowing in rainfall-deficient areas.
- Reduced soil moisture during important crop-growth stages.
- Higher dependence on groundwater and irrigation.
- Greater risk to rain-fed agricultural areas.
- Potential pressure on Kharif crop yields.
Groundwater and Reservoirs Under Pressure
When monsoon rainfall remains below normal, agricultural areas increasingly depend on groundwater and stored surface water. Prolonged dry spells can accelerate groundwater extraction and reduce the opportunity for natural recharge.
Reservoir and river inflows are also important for irrigation and drinking-water supply. Lower rainfall can reduce inflows into major water systems, making water management more challenging during the post-monsoon period.
The situation is particularly important for Rayalaseema, where water availability is already a major development and agricultural concern. Continued rainfall shortages could increase pressure on irrigation systems and groundwater reserves.
What Does the Rainfall Deficit Mean for Farmers?
A 29% seasonal rainfall deficit does not mean every farmer or every district has experienced the same level of drought. Rainfall distribution varies significantly by location, crop, irrigation access and timing of rainfall.
However, farmers dependent on rain-fed agriculture face greater risks when rainfall is both below normal and poorly distributed. In such areas, crop diversification, water conservation and timely agricultural advisories become particularly important.
Andhra Pradesh Rainfall: Key Numbers
| Monsoon Period | June to September 2026 |
| Actual Rainfall | 368.1 mm |
| Normal Rainfall | 521.6 mm |
| Seasonal Deficit | 29% |
| Monsoon Ranking | Driest in 13 years |
| Major Weather Factor | El Niño conditions |
Government Response and Agricultural Planning
The rainfall shortage has increased the need for water conservation, crop planning and support measures for affected agricultural communities. The state government has been focusing on crop diversification, water management, crop insurance and contingency planning in response to the weather conditions.
Earlier in the season, farmers in water-deficient areas were advised to avoid water-intensive cultivation where adequate irrigation water was not available and consider less water-intensive crops.
Andhra Pradesh has also declared drought conditions in 388 mandals across 21 districts for Kharif 2026, including 283 mandals classified as severely affected and 105 as moderately affected.
Could Water Stress Continue Into 2027?
The impact of a weak monsoon can continue beyond the end of the rainy season because reservoirs, groundwater systems and agricultural water demand respond over a longer period.
Current concerns are focused on whether available water resources will be sufficient through the end of the year and into the next agricultural cycle. The situation will depend on post-monsoon rainfall, reservoir storage, groundwater recharge and water-management decisions.
Therefore, the 2026 rainfall deficit is not only a seasonal agriculture issue but also a potential water-security concern for the coming months.
What Should Farmers Watch Next?
- Post-monsoon rainfall forecasts and local weather advisories.
- Reservoir storage and irrigation-water availability.
- Groundwater levels in rainfall-deficient areas.
- Government crop advisories and contingency plans.
- Crop insurance and eligible drought-relief measures.
- Water requirements for the upcoming Rabi agricultural season.
Key Takeaways
Andhra Pradesh Rainfall Deficit 2026 FAQs
Why is Andhra Pradeshs 2026 monsoon being called the driest in 13 years?
The state received around 29% less rainfall than normal during the June to September southwest monsoon season, making 2026 the driest monsoon in Andhra Pradesh in 13 years.
How much rainfall did Andhra Pradesh receive in 2026?
Andhra Pradesh received around 368.1 mm of rainfall during June to September, compared with a normal rainfall of 521.6 mm.
What caused the rainfall deficit?
The prevailing El Niño conditions were a major factor associated with the weak southwest monsoon and rainfall deficit across Andhra Pradesh.
Which areas of Andhra Pradesh are most affected?
Several districts in Rayalaseema and southern Andhra Pradesh have experienced substantial rainfall deficits, while rainfall performance has varied across coastal districts.
Will the rainfall deficit affect agriculture?
Yes. Poor and irregular rainfall can affect sowing, soil moisture, crop establishment and yields, particularly in rain-fed agricultural areas.
Has Andhra Pradesh declared drought in affected areas?
Yes. The state has declared 388 mandals across 21 districts drought affected for Kharif 2026, with 283 classified as severely affected and 105 as moderately affected.
Conclusion
Andhra Pradeshs 2026 monsoon has ended with a significant 29% rainfall deficit, making it the states driest southwest monsoon in 13 years. The shortage has already affected agricultural planning and increased pressure on groundwater and water-storage resources.
With drought declared across 388 mandals in 21 districts, the focus now shifts toward water conservation, farmer support, reservoir management and preparation for the next agricultural season. The availability of post-monsoon rainfall and the condition of groundwater and reservoirs will remain critical for Andhra Pradeshs water and agriculture outlook.
