Top 5 Cities: Muscat, Seeb, Salalah, Bawshar, and Sohar

This month in numbers

Oman experienced its warmest April–June period on record, with an average temperature of 33.09°C, an anomaly of +1.8°C compared to the 1961–1990 baseline. This marks the 1st warmest such period in 86 years of records. June 2026 itself was the 8th warmest June on record, with an average temperature of 34.63°C, an anomaly of +1.1°C. Globally, June 2026 was the 3rd warmest June for land temperatures, and the April–June period ranked as the 2nd warmest for global land temperatures.

What changed

The past three months have seen Oman significantly warmer than its historical average, setting a new record for the April–June period. This trend aligns with the broader picture of increasing temperatures across the Arabian Peninsula. Oman's 12-month rolling anomaly places it 129th out of 234 regions globally, indicating a substantial warming trend compared to many other areas.

What’s driving change?

The persistent heat in Oman is largely driven by the , as higher-latitude regions tend to warm faster than the tropics. Additionally, the effect likely plays a role, where arid regions warm more rapidly due to the lack of evaporative cooling. Oman experienced extreme heat events in June, with the Wilayat of Mahout recording a blistering peak of 50.4°C. Other areas also saw temperatures in the high 40s, including Dima Wa Tayeen at 49.4°C and Fahud at 48.6°C. Heavy rain and thunderstorms also lashed parts of Oman towards the end of June, particularly in the Al Hajar Mountains and Dhofar Governorate.

Looking ahead

The Civil Aviation Authority forecasts that Oman is expected to experience hotter-than-normal temperatures and below-average rainfall over the next three months, from July to September 2026.

FAQs

FAQs

How is the climate in Oman changing?

Oman is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.

Where does the climate data for Oman come from?

Climate data for Oman comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.

What is the climate baseline used on this page?

Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.

Which areas does the Oman climate data cover?

How often is the Oman climate update refreshed?

The Oman climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
