The IMD Rainfall Forecast has projected below-normal rainfall across India in August 2026, while warning of heavy rainfall in isolated parts of Assam. The India Meteorological Department expects August rainfall to reach around 94% of the long-period average, according to reports citing the latest forecast.
The IMD Rainfall Forecast presents a mixed monsoon outlook. While the national rainfall outlook points toward a weaker August, localized weather systems can still produce intense rainfall in parts of the Northeast.
Assam remains particularly important because heavy rain can quickly worsen flooding, landslide, and transportation risks in vulnerable areas. Moreover, the latest IMD weather bulletin continues to identify rainfall activity across the Northeast during the current forecast period.
The contrasting national and regional outlooks highlight the uneven nature of monsoon rainfall. Therefore, below-normal rainfall at the national level does not rule out intense rainfall events in individual districts or pockets.

IMD Rainfall Forecast Projects Below-Normal August Rainfall
The IMD Rainfall Forecast indicates that India could receive around 94% of its long-period average rainfall during August. Reuters reported that the forecast marks a below-average outlook following rainfall close to normal in July.
Moreover, the national forecast does not mean that every region will experience dry conditions. Rainfall distribution can vary significantly between states and even between neighbouring districts.
The IMD’s current extended forecast indicates that rainfall activity during the week of August 6–12 will remain near normal across much of the country, while some regions could experience normal to above-normal activity.
Consequently, authorities must consider both broader seasonal trends and short-term weather systems when assessing rainfall risks.
The forecast also comes amid continuing concerns about the influence of developing El Niño conditions on India’s monsoon performance.
Assam Remains Under Watch for Heavy Rainfall
The IMD Rainfall Forecast carries particular significance for Assam because isolated heavy rainfall can create serious local impacts even when national rainfall remains below normal.
According to the latest IMD bulletin, rainfall activity continues across parts of Northeast India during the current forecast period.
Moreover, Assam’s extensive river network and low-lying areas can increase the consequences of intense rainfall. Heavy showers may contribute to waterlogging, river-level rises, road disruptions, and localized flooding.
The IMD maintains dedicated rainfall monitoring for districts and states, providing daily, weekly, monthly, and cumulative rainfall information.
Therefore, residents and local authorities need to follow updated weather information rather than relying solely on the broader monthly rainfall outlook.
The available forecast information does not indicate that all of Assam will experience heavy rainfall. Instead, the warning concerns isolated pockets, reflecting the localized nature of intense monsoon events.
Mixed Rainfall Pattern Creates Regional Challenges
The IMD Rainfall Forecast demonstrates how a below-normal national rainfall outlook can coexist with heavy rainfall events in specific regions. This distinction remains particularly important for Northeast India.
Furthermore, localized heavy rainfall can create significant short-term disruption even when seasonal rainfall totals remain below average. A few intense rainfall events can quickly overwhelm drainage systems and affect roads, bridges, agriculture, and settlements.
The latest IMD bulletin shows that rainfall patterns vary considerably across India during the current forecast period.
Meanwhile, the department’s extended forecast expects rainfall activity to remain near normal nationally during the August 6–12 period.
Consequently, authorities must continue combining seasonal forecasts with short-range warnings and local rainfall observations.
For Assam, this approach remains particularly important because heavy rainfall can create localized hazards despite the broader national rainfall outlook.
Conclusion
The IMD Rainfall Forecast points toward below-normal rainfall across India in August 2026, with rainfall expected at around 94% of the long-period average. However, the national outlook does not eliminate the possibility of intense rainfall in individual regions.
Assam remains under weather watch as the IMD continues to forecast rainfall activity across the Northeast and warns of heavy rainfall in isolated areas.
Furthermore, the contrasting forecasts underline the importance of monitoring localized weather developments. Overall, the IMD Rainfall Forecast suggests a weaker national rainfall month while highlighting the potential for significant regional rainfall events across Assam.
FAQs
1. What does the latest IMD Rainfall Forecast say about August?
The IMD Rainfall Forecast projects below-normal rainfall across India in August 2026, at around 94% of the long-period average.
2. Is Assam expected to receive heavy rainfall?
Yes. The IMD has highlighted the possibility of heavy rainfall in isolated parts of Assam despite the broader below-normal national outlook.
3. Does below-normal national rainfall mean Assam will remain dry?
No. National rainfall averages can mask significant regional differences. Assam can still experience intense localized rainfall.
4. Why can heavy rain occur during a below-normal rainfall month?
Monsoon rainfall does not distribute evenly. Short-lived weather systems can produce intense rainfall in particular locations even when overall monthly rainfall remains below average.
5. Where can rainfall information be monitored?
The IMD provides daily, weekly, monthly, and cumulative rainfall information through its official rainfall monitoring systems.
