Extreme Heat Challenges in Freetown

Freetown, the capital of Sierra Leone, faces severe issues with extreme heat, with temperatures soaring past 35 degrees Celsius. This extreme weather not only affects comfort but also leads to an increase in health risks and hampers the livelihoods of residents, particularly in crowded neighborhoods and open-air markets. For example, the intense heat can cause food to spoil more quickly, leading to financial losses for vendors and contributing to food scarcity. The community's reliance on inadequate housing materials, such as corrugated zinc, exacerbates the situation, pushing individuals outside where they struggle against the sweltering heat.
