El Salvador Climate – June 2026 Update
Top 5 Cities: San Salvador, Soyapango, Santa Ana, San Miguel, and Mejicanos
This month in numbers
El Salvador experienced its 6th warmest June on record in 2026, with an average temperature of 26.46°C, which is 1.1°C above the 1961–1990 baseline. The three-month period from April to June 2026 was the 5th warmest on record, with an average temperature of 27.59°C, a significant 1.4°C above the baseline. Globally, land temperatures for April–June 2026 ranked as the 2nd warmest on record, at 1°C above the baseline.
What changed
The consistent warmth in El Salvador over the past few months aligns with a broader trend of rising temperatures. The country's average temperature for 2025 was 26.91°C, making it the 3rd warmest year on record, and the long-term trend shows a warming of +1.28°C compared to the 1961–1990 baseline. This regional warming is occurring within a global context where land temperatures are also significantly above average.
What’s driving change?
The current strong El Niño event is a significant driver of the warmer and drier conditions in El Salvador. El Niño typically brings warmer and drier weather to Mexico and Central America during the June-to-October rainy season, increasing the risk of drought and impacting crop and water supplies. This has been evident with a rainfall deficit between May and July, and forecasts for below-normal rainfall in the coming months. Additionally, in June 2026, Tropical Depression Cristina brought heavy rainfall, urban flooding, landslides, and damage to nearly 200 homes in El Salvador, highlighting the region's vulnerability to extreme weather events during this period. The warming waters in the Pacific basin, associated with El Niño, can enhance the frequency and intensity of such storms.

Shifting Seasons
Wet / dry seasonsKöppen Aw · TropicalEl Salvador doesn't have a warm/cold cycle - its monthly temperature range is only 2.6°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 70× as much rain as the driest). So we track how the wet season has shifted instead.

FAQs
FAQs
How is the climate in El Salvador changing?
El Salvador 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 El Salvador come from?
Climate data for El Salvador 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 El Salvador climate update refreshed?
The El Salvador 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.
