Oman Climate
Top 5 Cities: Muscat, Seeb, Salalah, Bawshar, and Sohar
This month in numbers
Oman experienced its 3rd warmest April on record, with an average temperature of 30.9°C, marking an anomaly of +2.5°C compared to the 1961–1990 baseline. This continues a significant warming trend, as the February–April 2026 period also ranked as the 3rd warmest on record for the country, with an average of 26.44°C, an anomaly of +1.9°C. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C.
What changed
The past three months have seen Oman consistently warmer than average, aligning with a broader regional and global warming trend. The country's average temperature for February–April 2026 was 26.44°C, ranking 3rd warmest in 86 years of records. This trend is consistent with the long-term warming observed in Oman, which has seen an increase of +1.16°C against the 1961–1990 baseline. Oman's 1-month anomaly for April placed it 92nd out of 234 regions globally, while its 3-month anomaly ranked 90th.
What’s driving change?
The sustained warmth in Oman is influenced by the broader trend of land warming faster than ocean, a significant climate driver in arid regions. The current ENSO state is Neutral, with a +0.11°C anomaly in the NOAA ONI 3-month (FMA 2026). However, forecasts indicate a strong likelihood of an El Niño developing in the coming months, with a 79% chance for June-July-August. This shift could bring further warming to the region. Oman also experienced significant rainfall and flash floods in March and early April due to a low-pressure trough, which led to at least 10 fatalities and widespread disruption, prompting remote work and learning advisories across several governorates. These events, while bringing much-needed water to dams, also highlight the increasing intensity of extreme weather events in the region.
Looking ahead
The NOAA CPC forecast suggests a high probability of El Niño developing and strengthening through the summer months, which typically brings warmer conditions to the region.

Data Sources for Oman
Every figure on this page is sourced from official, openly published climate datasets. Anomalies are calculated against the 1961–1990 baseline (temperature) and 1991–2020 (rainfall, sunshine, frost) — see the Methodology & Sources page for the complete dataset list and update calendar.
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 trend rate is shown as °C per decade in the headline panel; you can also see 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.
