Impact of Extreme Weather on Economic Productivity

Summer Heat to Hit Productivity in India

The sweltering heat of tropical India has severe consequences on both people and businesses during the summer months. The extreme temperatures lead to heatstroke, dehydration, exhaustion, and heat stress, causing people to restrict their travel and outdoor activities to non-midday hours. This often results in a decline in productivity.

A study conducted by Vidhya Venugopal, PK Latha, and Rekha Shanmugam in Tamil Nadu has found a significant rise in the risk of worker productivity loss during elevated levels of wet bulb globe temperature (WBGT), a measure of heat stress. The study's findings demonstrate severe productivity and economic losses associated with high WBGT levels, affecting livelihoods and the regional economy.

The impact of high temperatures is not unique to India. A global study by the International Labour Organization estimates that by 2030, high temperatures and slow pace of work will result in a loss of 2 percent or more of annual working hours.

In India, industries such as farming, construction, and manufacturing, which involve physical work, will be severely affected. Milk production drops during the summer season, and the mortality risk rises for livestock and fisheries. With weather forecasts predicting below normal rains and a possible onset of El Nino climate pattern this year, the risk to crop yields has increased. Additionally, global fuel supply constraints may lead to inflation exceeding the Reserve Bank of India's projections, which can erode consumer incomes.

Input Costs Rise, Inflation Looms

Input costs are already rising at consumer goods companies and manufacturing industries. Companies are slowly passing on the increasing input costs to consumers. Economists warn that inflation may rise and exceed the Reserve Bank of India's projections, which can have a negative impact on consumer incomes.

On the other hand, demand for goods and services that help consumers cope with summer heat may rise. Varun Beverages, a PepsiCo bottler and carbonated drinks maker, reported healthy growth in the March 2026 quarter. The stock is up about one-third in the last one month.
