Understanding Why Dhaka’s 37°C Temperature Feels Like 44°C

As Dhaka grapples with moderate to severe heatwaves, residents are left questioning why the recorded temperature of 37°C can feel like a scorching 44°C. The Meteorology Department’s extended heat alert, now spanning 72 hours, highlights the widespread occurrence of these heatwaves, with forecasts suggesting no immediate relief unless rainfall intervenes. Inquisitive minds turn to Google for temperature checks, where the displayed temperature may starkly contrast with the “feels like” temperature, raising curiosity and confusion. This “feels like” temperature, also known as the heat index, accounts for various environmental factors such as humidity levels, wind speed, and urbanization, collectively shaping the perceived weather conditions. Meteorologists elucidate that urban areas, characterized by higher human activity and industrialization, tend to exhibit elevated perceived temperatures compared to rural counterparts. Moreover, during summer, humidity impedes sweat evaporation, amplifying discomfort and augmenting the perceived heat index. Conversely, winter’s wind chill factor underscores how wind speed influences heat dissipation from the body, accentuating the sensation of cold. Understanding these nuances elucidates why the “feels like” temperature often diverges from the recorded air temperature, offering insights into the intricacies of human-perceived weather conditions.
