Highest Temperature Ever Recorded in Oman: 53.8°C (128.8°F)

Oman's highest reliably recorded temperature is 53.8°C (128.8°F), measured on June 21, 2018 at Quriyat (Coastal Al Sharqiyah).

Context

• This tied the highest temperature ever recorded in the Middle East (also set in Oman: 53.8°C at Wuqbah, near Fahud, Al Dhahirah, on July 1, 2017).
• Quriyat also holds the world record for highest "low" temperature: 42.6°C (108.7°F) on June 26, 2018 — the hottest night ever recorded.

Why Oman Gets So Hot

• Geography: Coastal plain + Hajar Mountains trap heat; subsidence from subtropical high.
• Sea Surface Temps: Arabian Gulf / Gulf of Oman >35°C in summer — no cooling.
• Aridity: Minimal soil moisture → all solar energy → sensible heat.
• Climate Change: Increasing frequency of extreme heat events.

Measurement Standards

• WMO-certified stations; shaded, ventilated, 1.5 m above ground.
• Not satellite estimates (which can read 60–70°C on ground surface).

Oman is on the front line of global extreme heat.
