Why are Kuwait’s coastal areas less extreme in temperature than its interior?

Kuwait’s coastal areas experience less extreme temperatures compared to the interior primarily due to the moderating influence of the Persian Gulf. The warm waters of the gulf help temper the desert climate along the seacoast.1

While the interior can experience more severe temperature fluctuations—including occasional frost during the winter—the coastal regions are shielded from such extremes. The hydrology of the gulf, characterized by high surface-water temperatures, plays a significant role in maintaining this more moderate environment.12
