Climate change makes coastal cities vulnerable to heatwaves therefore allowing them not only to increase in temperature but also in humidity. Inland areas are mostly dry and hot, whereas coastal regions experience hot and humid weather which gives rise to a problem of cooling down by means of sweating. As a result, even if the temperature is lower than in inland cities, coastal heatwaves pose serious danger.
What Makes Coastal Heatwaves More Dangerous?
1. High Humidity
This means the body can’t cool itself well enough since sweat cannot evaporate giving rise to chances for heat strain and heat stress problems.
2. Rising Sea Surface Temperature
Higher sea surface temperature leads to hotter humid air making the situation worse for coastal cities.
3. Urban Heat Island Phenomenon
Dense concrete structures along with limited green area lead to the fact that cities perform creating heat enviroments, especially during night hours.
4. Tropic Nights
Certain cities witness the phenomenon of tropic night which means that the air does not cool down and gives the body no time to recover from daytime heat.

Conclusion
High temperatures coupled with high humidity and rapid urbanization make heatwaves increasingly threatening in coastal areas. Considering the fact that climate change continues contributing to the worsening of extreme weather phenomena, cities should start spending money on infrastructure and health measures that are climate resistant.
FAQs
1. Why is it hotter in coastal areas compared to inland areas?
The high humidity prevents sweating and makes the body retain heat.
2. What does the term tropical night mean?
A tropical night is a night with a high temperature.
3. Who is at risk during heatwaves in coastal areas?
The elderly and children are the people who are most vulnerable in this case.
4. What could be done to reduce heat hazards in coastal cities?
The measures that should be taken include creating more green areas, using reflective materials in buildings, improving early warning systems, and making cooling centers easily accessible.
