Central Asia's Record Heat Strains Power Grids, Damages Roads and Puts Health at Risk

Temperatures climb into the upper 40s as services struggle

Temperatures reaching 46 degrees Celsius in Tajikistan's Shakhristan province, with forecasts of 48 degrees in parts of Khatlon, have put Central Asia's electricity networks, roads and public health services under pressure. As of July 30, 2026, an exceptional heatwave affecting Tajikistan, Kyrgyzstan, Uzbekistan, Kazakhstan and Turkmenistan has broken temperature records and disrupted everyday life, with the most severe conditions reported from mid-July.

Dushanbe has recorded maximum temperatures near 43 degrees, with forecasts pointing to 44 degrees. Other recent readings include 47.6 degrees in Turkmenabat, 45 degrees in Shymkent, 44.6 degrees in Syrdarya, 43.2 degrees in Bishkek, and 42.7 degrees in both Samarkand and Fergana. Some locations across the region have reported temperatures above 50 degrees during the wider period of extreme heat.

Tajikistan has experienced repeated electricity cuts, while Kyrgyzstan has introduced temporary shutdowns in some areas. Uzbekistan has ordered dangerous outdoor work to stop during the hottest hours. In Kazakhstan, maintenance crews have been sent to repair roads that expanded and lost their shape in the heat.

Weather specialists have cautioned that official air temperatures are measured in the shade. A thermometer sitting in direct sunlight beside hot asphalt can show a much higher number. People and infrastructure at ground level still face dangerous conditions when sunlight and heated surfaces add to their exposure.

The disruption has developed across several periods, from earlier warming episodes to the current emergency:

• Earlier in the year, a separate Central Asian heatwave was examined by World Weather Attribution, which found that human-caused climate change made it at least 4 degrees hotter.
• In June, Kazakhstan recorded a 26 percent increase in emergency-treated cases of arterial hypertension compared with the same month in 2025.
• From mid-July, the most severe conditions of the current heatwave brought extreme temperatures and pressure on essential services across the region.

Cooling demand pushes electricity networks to their limits

Households and businesses are running air conditioners, refrigerators, fans and other cooling equipment for longer periods. The resulting rise in electricity consumption is adding strain to equipment already exposed to high outdoor temperatures.

Dushanbe residents and people elsewhere in Tajikistan have reported unannounced outages. Complaints have come from Zarafshon, Chimteppa and parts of the capital identified as districts 33 and 102, as well as towns and villages in other areas. Residents have also reported overheated or damaged cables.

Distribution networks carry electricity through local lines and transformers to homes and businesses. When demand peaks across a large area, those networks can reach their operating limits. High outdoor temperatures can make equipment less reliable just as additional cooling demand requires it to carry more electricity.

Kyrgyzstan's national electricity grid has said consumption reached record levels and the network was operating at maximum capacity. Temporary cuts in Bishkek and the Chuy region followed emergency shutdowns involving two high-voltage power lines.

Bishkek's outages disrupted water and telecommunications services in some areas. Elevators stopped working and traffic lights went out, creating risks for residents and emergency responders. The failures show how a loss of electricity can spread beyond homes and businesses to other services people rely on.

An Asian Development Bank assessment found that heat, drought, floods and other climate hazards are increasingly disrupting electricity generation, transmission and distribution across Asia. Hydropower depends on water supplies that can become less predictable. Thermal power plants may lose efficiency when the water used to cool them is scarce or unusually warm, while power lines and substations can fail during extreme weather.

Road damage and dangerous working conditions demand action

Kazakhstan has identified six areas of thermal deformation on concrete roads in the Zhambyl, Pavlodar and Turkestan regions. Thermal deformation happens when road materials expand under intense heat and lose their shape. Maintenance teams equipped for specialized repairs have been dispatched to restore the affected sections.

Uzbekistan's State Labour Inspectorate has ordered local governments to protect public works employees during the hottest hours. Work considered dangerous to life or health must be suspended between 10 a.m. and 5 p.m. Employers are expected to provide flexible schedules, drinking water, protective equipment and shaded places to rest.

Workers who have not completed required medical examinations, or who have been judged medically unfit, cannot be assigned to such duties. The protections are especially relevant to construction, road maintenance, agriculture and other jobs involving prolonged sunlight and physical exertion.

Tajikistan's labour protections also allow employees to stop work when they identify a danger they cannot remove. Nawruz Odinaev, head of the Khimoya law firm, explained that employees using this right should retain their average wage until the danger has been eliminated.

If an employee discovers a danger to their life and health and is unable to eliminate it, they have the right to stop work. The employee's average wage is maintained until the hazard has been eliminated.

Korvon market and other open commercial sites have installed fresh water dispensers. The measures give traders and visitors access to drinking water during long periods of exposure, alongside the broader workplace protections needed for people whose livelihoods keep them outdoors.

Health risks extend beyond dehydration

Extreme heat can cause dehydration, heat exhaustion and heatstroke. It can also worsen cardiovascular, respiratory and kidney conditions. Older people, people with chronic illnesses, pregnant women and outdoor workers face particularly high risks, as do people living in poorly ventilated housing or unable to afford reliable cooling.

Kazakhstan's Ministry of Health reported a 26 percent increase in emergency-treated cases of arterial hypertension in June compared with the same month in 2025. Arterial hypertension means high blood pressure. The increase illustrates the pressure that health services can face during hot conditions before a crisis is formally declared.

Kazakhstan is developing health services able to withstand climate hazards. Health specialists have also called for a national Heat-Health Action Plan based on World Health Organization guidance. Such a plan would assign responsibilities for protecting people during dangerous temperatures, bringing health services and other public agencies into a coordinated response.

People can reduce their exposure by drinking water regularly, avoiding strenuous activity during the hottest hours, wearing light clothing and seeking shade or cooler indoor spaces. These measures are especially relevant when power cuts make cooling less reliable or when work and travel require time outdoors.

Children face risks at home, outdoors and before birth

UNICEF reports that more than 92 million children across Europe and Central Asia are already exposed to frequent heatwaves. In Central Asia, the frequency, duration and severity of heatwaves have each risen by about 30 percent over the past 60 years. Children therefore face hot spells that occur more often, last longer and are more severe.

Infants have limited ability to regulate their body temperature. Older children face risks from outdoor play, sports and dehydration. Schools, kindergartens and clinics need shaded spaces, clean water, ventilation and staff trained to recognize early signs of heat stress.

Pregnancy is another period of vulnerability. High temperatures during pregnancy have been linked with increased risks of premature birth, low birth weight and other complications. Protecting pregnant women from prolonged heat exposure is part of protecting children before they are born.

Children and infants should never be left in parked vehicles. Caregivers should also avoid covering strollers with heavy cloth, because it can restrict airflow and trap heat. Access to water and cooler spaces matters for both children and the adults caring for them.

Persistent heat sits within a wider warming trend

Central Asia has always experienced hot summers, especially in lowland areas. Jamila Baidullaeva, head of Tajikistan's Hydrometeorological Centre, has said that temperatures near 40 degrees in July can be normal in those locations. Conditions become abnormal when that heat persists for four or five consecutive days.

World Weather Attribution examined a separate Central Asian heatwave earlier in the year across Kazakhstan, Uzbekistan, Turkmenistan, Tajikistan and Kyrgyzstan. Its rapid attribution analysis found that human-caused climate change made that event at least 4 degrees hotter. The researchers warned that the estimate may be conservative.

Attribution analysis examines how climate change affects a particular weather event. Burning coal, oil and gas increases the concentration of gases that trap heat in the atmosphere, raising the temperature from which hot spells develop. A naturally occurring period of hot weather can consequently become more intense and last longer.

Ben Clarke, a study author and researcher at Imperial College London, described the scale of the climate contribution as far above what attribution studies commonly find.

Our heatwave studies often detect changes of 2 to 4 degrees, so 10 degrees is quite frankly bonkers.

The researchers said events that were once rare can now occur roughly once every three years in a warming climate. Their findings place the region's exposure to extreme heat within a longer change in temperatures and the likelihood of severe hot spells.

The World Meteorological Organization has reported that Asia warmed at almost twice the rate seen during the earlier part of the modern climate record. Its assessment of 2025 found prolonged heatwaves across Central Asia. Kazakhstan recorded temperatures as much as 14 degrees above normal in March, April, June and July.

Glacier loss adds pressure to water and farming

The Tien Shan and Pamir mountain ranges feed water systems supporting farms, cities and industry across national borders. Central Asia depends heavily on mountain snow and glaciers for river flows, irrigation and hydropower, connecting conditions in the mountains with water and electricity supplies far downstream.

The WMO reported that all 23 monitored glaciers in High Mountain Asia lost mass during the 2025 glaciological year, the period used to track glacier growth and loss. In the Tien Shan and Pamir mountains, below-average winter snow and persistent warmth from May to September drove substantial ice loss.

Glaciers can supply more water for a time as they melt faster. Continued loss, however, reduces the reserve available during dry seasons. The immediate increase in meltwater and the longer decline in stored ice create different pressures for places that depend on mountain water.

Heat and drought can damage crops, reduce livestock productivity and increase demand for irrigation. Agricultural workers may need shorter shifts, while households face higher costs for cooling and water. The effects can spread through food prices and household incomes, especially where social protection is limited or work is informal.

A hot, dry period can also increase wildfire and dust risks. Heavy rain after prolonged heat can produce flash floods and soil erosion. Across Asia, the WMO has recorded a combination of extreme heat, drought, glacier loss and intense rainfall, placing added pressure on emergency services and local governments.

Heat warnings need a public health response

Authorities can reduce harm by treating heat as a public safety emergency rather than only a weather event. Alerts need to explain the expected effects on health, electricity, water and transport, alongside temperature forecasts. Messages must reach outdoor workers, schools, older residents and people in remote communities.

Public health agencies can establish heat action plans that give hospitals, municipalities, employers and social services clear responsibilities. Possible measures include checks on vulnerable residents, extended clinic hours, cooling centres, water distribution and temporary changes to school or work schedules.

Hospitals, schools and neonatal units need reliable backup power and cooling systems. An electricity outage during extreme heat can quickly become a medical emergency, particularly where patients or infants depend on controlled indoor conditions.

Kazakhstan's work on health services able to withstand climate hazards and Uzbekistan's restrictions on dangerous outdoor work address different parts of the same problem. Health care, labour protection and municipal services all face demands that rise during prolonged heat.

Power planning, cooler cities and cooperation across borders

The Asian Development Bank has warned that new power projects should be designed for future climate conditions rather than relying only on historical weather records. Electricity systems must account for both hotter surroundings and increased demand for cooling.

Stronger transmission equipment, better insulated buildings, local solar generation, battery storage and demand management can reduce the risk of widespread outages. Demand management means adjusting electricity use to reduce pressure during periods when the network is busiest. These measures address both the supply of power and the amount needed at peak times.

Trees, shaded public spaces, reflective roofs, improved ventilation and access to clean water can reduce heat exposure in dense neighbourhoods. Changes to buildings and public spaces can help residents find relief while limiting pressure on cooling equipment.

Regional cooperation matters because rivers, mountain ranges, electricity networks and weather systems cross borders. Shared forecasts, coordinated water management and common standards for heat warnings can help countries respond faster. Early warnings work best when people trust the message and have the resources to act on it.
