Top 5 Cities: Sanaa, Aden, Taiz, Hodeidah, and Ibb
This month in numbers
Yemen experienced its 3rd warmest April on record in 2026, with an average temperature of 27.78°C, a significant 2.3°C above the 1961–1990 baseline. The period of February–April 2026 also ranked as the 4th warmest on record, with an anomaly of +2°C. Globally, April 2026 was the 2nd warmest April for land temperatures, and the February–April period was the 2nd warmest for global land temperatures.
What changed
The consistent warmth seen in April follows a trend of elevated temperatures throughout the past few months. February 2026 saw temperatures 2.0°C above average, and March was 1.7°C above average. This sustained warmth places Yemen's recent seasonal temperatures significantly higher than historical averages. The country's long-term warming trend stands at +1.66°C compared to the 1961–1990 baseline, with 2025 being the warmest year on record.
What’s driving change?
The elevated temperatures in Yemen are occurring during a Neutral ENSO phase, though a transition to El Niño is forecast to become the most likely state from May–July 2026 onwards, with an 87% probability by July–September 2026. ENSO tracker. This warming trend is further exacerbated by the effect, as Yemen is a largely arid country. Beyond the temperature anomalies, Yemen has been severely impacted by heavy rainfall and widespread flooding since late March 2026. The rainy season began earlier than usual, with significant intensification from March 27th, affecting over ten of Yemen's 22 governorates. These floods have resulted in at least 30 fatalities and affected nearly 12,000 families, with some reports suggesting up to 30,000 households impacted. Critical infrastructure, including electricity, water supply, and transport networks, has sustained significant damage, and the risk of waterborne diseases is increasing due to contaminated water sources.
Looking ahead
Rainfall in Yemen is expected to intensify over the next few weeks, potentially worsening the current flood disaster.

FAQs
How is the climate in Yemen changing?
Yemen 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 Yemen come from?
Climate data for Yemen 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.

How often is the Yemen climate update refreshed?
The Yemen 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.
