Shifting Seasons

Wet / dry seasonsKöppen Aw · Tropical

El 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 19× as much rain as the driest). So we track how the wet season has shifted instead.

Data Sources for El Salvador

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 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.

What is the climate like in El Salvador?

El Salvador has a tropical climate (Köppen Aw: Tropical savanna (dry winter)), with only modest temperature variation through the year, but a pronounced wet and dry season. April is typically the warmest month, averaging 28.0°C, while November is the coldest at 25.7°C. Annual precipitation averages around 1400mm, concentrated mostly in the wet season.

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.

Which areas does the El Salvador climate data cover?

The El Salvador climate profile covers San Salvador, Soyapango, Santa Ana, San Miguel and surrounding areas. Temperature, rainfall and emissions data for El Salvador

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.

What counts as a Heatwave Day on the El Salvador climate page?

Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.

Does the El Salvador climate page include frost and snow data?

Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
