Despite not breaking the top ten in terms of hottest points globally, the city’s sauna-style tropical climate, coupled with its legendary humidity, creates a unique and challenging environment, particularly during its ultra-moist wet season.

The humidity in Hong Kong exacerbates the discomfort caused by the heat, making the city feel more like a steam room than an international metropolis. Although daytime temperatures typically reach around 30 degrees Celsius, the high moisture content in the air creates a muggy and oppressive atmosphere.

The humidity clings to the skin, causing a sticky and uncomfortable feeling, and making everyday activities more challenging.

To cope with the extreme conditions, Hong Kong’s residents have developed specific routes that take them through as many air-conditioned shopping malls as possible when moving between destinations.

9. Athens (Greece)

Once notorious for its severe pollution, Athens has now established itself as a European frontrunner in another realm: extreme heat.

The Greek capital experiences scorching temperatures exceeding 40 degrees Celsius (104 degrees Fahrenheit) during the summer months, and it proudly holds the record for the highest temperature ever recorded in Europe with a scorching 48 degrees Celsius (118.4 degrees Fahrenheit) in July.

Compounding the heat issue is the presence of smog in the city. While the air quality has improved since its peak in the 1970s, Athens still experiences bouts of grey haze, which hampers the city’s ability to effectively moderate temperatures.

As temperature fluctuations increase across the continent, it comes as no surprise that the European Union (EU) has emerged as the fastest-growing market for heat pumps. These innovative systems offer efficient heating and cooling solutions, helping to address the challenges posed by extreme heat in urban areas like Athens.

The EU’s focus on heat pumps reflects a broader trend toward sustainable and energy-efficient technologies. Heat pumps utilize renewable energy sources, such as geothermal or air-source heat, to provide heating and cooling for buildings.

By harnessing natural heat from the environment, they offer a more environmentally friendly alternative to traditional heating and cooling systems. Athens’ experience with extreme heat and the corresponding demand for cooling solutions highlights the importance of adapting to changing climate conditions.

As cities worldwide grapple with rising temperatures, sustainable technologies like heat pumps can play a crucial role in mitigating the impact of heat waves and promoting more comfortable and resilient urban environments.

10. Cairo (Egypt)

Located on the banks of the renowned Nile River, Cairo holds the distinction of being the largest city in Africa and one of the hottest major cities worldwide.

As a result, Cairo’s residents experience a challenging blend of intense desert heat, often surpassing 40 degrees Celsius (104 degrees Fahrenheit), along with extreme humidity during the summer season.

The presence of the Nile River plays a crucial role in shaping Cairo’s climate.
