Coastal urban areas often experience moderate summer temperatures due to the influence of large bodies of water. Ocean breezes and the thermal properties of water help regulate temperatures, preventing extreme heat typically found further inland. For example, a city situated on a coastline might have average summer highs in the 70sF (low 20sC) while a city a few hundred miles inland could experience temperatures in the 90sF (mid 30sC) or higher.
Such moderated temperatures offer numerous advantages. They provide a comfortable environment for residents and tourists, reducing heat-related health risks and promoting outdoor activities. Historically, coastal settlements benefited from these cooler conditions, allowing for thriving trade and agriculture. The predictable and temperate climate also played a crucial role in the development of popular seaside resort towns.
