How do Oman’s coastal climate and interior climate differ?

Oman’s climate is primarily defined by the contrast between its coastal and interior regions:

• Coastal Climate: The coast is characterized by hot and humid conditions. In areas such as Muscat, summer temperatures frequently reach 110° F (43° C) with high humidity, while winters remain mild with average lows of about 63° F (17° C).12
• Interior Climate: The interior is hot and dry. While temperatures are generally similar to those on the coast, they become more moderate at higher elevations.12

Regional variations also exist, particularly in Dhofar, which is influenced by the summer monsoon. This makes the climate in Ṣalālah more temperate than that of northern Oman. Across the country, annual rainfall is minimal, averaging about 4 inches (100 mm), though precipitation is notably heavier in the mountains.12
