Dhaka Sizzles as Temperature Hits 40.1°C — Highest of 2025 So Far

 Dhaka experienced its hottest day of the year on May 17, 2025, as the temperature soared to a scorching 40.1 degrees Celsius, according to data from the Bangladesh Meteorological Department (BMD). This record-breaking heat has put residents under intense pressure and raised concerns about public health, energy use, and climate resilience in the capital.

The extreme heat is part of a larger heatwave pattern that has affected many regions of the country. Meteorologists note that the hot spell is expected to continue for several more days, particularly in central and southwestern districts. Urban areas like Dhaka are especially vulnerable due to the “urban heat island” effect, where buildings and paved surfaces trap heat and push temperatures even higher than in rural areas.

Local hospitals have already begun reporting increased cases of heat-related illnesses such as dehydration, heat exhaustion, and dizziness. Health officials are urging citizens to stay indoors during the peak afternoon hours, remain hydrated, and wear light, breathable clothing. Vulnerable groups, including the elderly, children, and outdoor workers, are at particular risk during this time.

“We are seeing a clear increase in patients with heat-related symptoms,” said Dr. Mahbuba Nasrin, a physician at Dhaka Medical College Hospital. “Many are coming in with fatigue, low blood pressure, and nausea due to prolonged exposure to the sun.”

In response to the growing heat, city authorities have advised schools to reduce outdoor activities and encouraged workplaces to implement flexible hours where possible. Social media platforms have been flooded with advice on how to cope with the heat, with hashtags like #StayCoolDhaka and #HeatwaveSafety trending among Bangladeshi users.

Experts point out that the increasing frequency and intensity of heatwaves in Bangladesh are linked to global climate change. The country, already one of the most climate-vulnerable in the world, is facing rising temperatures, unpredictable weather, and growing challenges in urban planning.

“The rising heat is not just an inconvenience — it’s a signal of deeper environmental changes,” said climate researcher Dr. Ziaur Rahman. “We need long-term strategies to adapt our cities and protect our citizens, especially as these events become more common.”

The heatwave has also affected electricity demand, as residents rely heavily on fans and air conditioners to stay cool. Load-shedding has been reported in some areas due to the surge in power usage. Authorities have urged the public to conserve electricity during peak hours to reduce strain on the grid.

As the country braces for continued high temperatures, public awareness and community support remain crucial. Simple actions like checking in on elderly neighbors, sharing clean drinking water, and minimizing outdoor work can help reduce the risks associated with extreme heat.

While the heatwave presents serious challenges, it also offers a moment for reflection on how Bangladesh can build greater resilience in the face of climate change. For now, staying informed, staying safe, and supporting one another are the best tools we have to weather this wave of heat.
