Himachal Pradesh Monsoon 2026: Rainfall Deficit vs ₹3,212 Crore Infrastructure Loss

As the 2026 मानसून (monsoon) season enters its final phase in Himachal Pradesh, the state presents a paradoxical weather story: a significant overall rainfall deficit coupled with devastating infrastructure damage and loss of life. While total rainfall remained below normal for much of the season, the intensity of localized events has left a staggering economic scar on the region.

Monsoon Withdrawal and Current Weather Outlook

According to the India Meteorological Department (IMD), the monsoon is now in its concluding stage. Weather activity is expected to remain somewhat active on September 17 and 18, with potential rain and thunderstorms in several areas. However, a weakening trend is predicted starting September 18, with clear skies expected across most of the state from September 19 to 22 [1].

While activity is slowing, the official withdrawal of the southwest monsoon from Himachal Pradesh typically occurs around September 25. Until then, temperatures in the plains have already begun to rise, with some cities experiencing humidity and heat spikes as the rain recedes [1].

The Rainfall Paradox: Deficits and Exceptions

Data from June 1 to September 15, 2026, reveals that Himachal Pradesh recorded a total of 615.5 mm of rain, which is 11% below the normal average of 689.6 mm [3]. This deficit became even more pronounced in the second week of September (September 8–15), where rainfall was 31% below normal [1].

However, this deficit was not uniform across the state. While Lahaul-Spiti saw a 100% deficit, other districts experienced surplus rainfall during the September 8–15 window:

• Shimla: 37% above normal
• Kangra: 25% above normal
• Una: 4% above normal

The 'Cost of Clouds': Infrastructure and Human Loss

Despite the overall rainfall deficit, the impact of the 2026 monsoon has been severe. Between June 30 and September 15, the estimated financial loss to the state reached ₹3,212.21 crore [2]. The Public Works Department (PWD) bore the brunt of this, with ₹2,744 crore in losses attributed to the destruction of roads and bridges [3].

Category	Impact/Losses (June 30 – Sept 15)
Total Financial Loss	₹3,212.21 Crore
PWD Infrastructure Loss	₹2,744 Crore
Houses Completely Destroyed	131
Houses Partially Damaged	502
Roads Closed (as of Sept 16)	59–60

Casualty Reports

Reports on casualties vary slightly between sources. Jagran reports 296 deaths, including 119 from natural disasters and 177 from road accidents [2]. Conversely, Live Hindustan reports a total of 308 deaths, specifying 124 rain-related deaths (landslides, flash floods) and 184 road accidents [3]. Shimla district emerged as the hardest hit, recording the highest number of fatalities (45).
