Guatemala Climate
Top 5 Cities: Guatemala City, Mixco, Villa Nueva, Quetzaltenango, and Escuintla
This month in numbers
Guatemala experienced its 30th warmest April on record, with an average temperature of 24.34°C, an anomaly of +0.9°C compared to the 1961–1990 baseline. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C. The three-month period from February to April 2026 was the 7th warmest on record for Guatemala, with an average temperature of 23.71°C, an anomaly of +1.6°C.
What changed
The recent three-month period (February–April 2026) saw Guatemala experiencing significantly warmer conditions, ranking 7th warmest in 86 years of records. This trend is consistent with the long-term warming observed in the region, with the latest full year (2025) being the warmest on record at 24.23°C. Guatemala's current 1-month temperature anomaly places it at 190th out of 234 regions globally, while its 3-month anomaly ranks it 121st.
What’s driving change?
The current climate patterns in Guatemala are being influenced by a combination of factors. The ongoing Neutral ENSO state, with a Niño 3.4 SST anomaly of +0.11°C, is expected to transition to an El Niño phase, with a 61% probability for May-Jul and 79% for Jun-Aug. Historically, El Niño conditions typically bring warmer and drier weather to Mexico and Central America, increasing drought risk during the rainy season (May-October) and potentially causing crop and water-supply stress, particularly in the Central American Dry Corridor. Guatemala has been experiencing a heatwave, with temperatures in Zacapa exceeding 43 degrees Celsius in April, leading to communities facing water shortages for up to 15 days. Additionally, there were reports of flash floods in southern Guatemala City, specifically in Villa Nueva and San Miguel Petapa, in early April, caused by heavy rains and strong winds. Volcanic activity was also noted, with Santiaguito Volcano experiencing weak to moderate explosions in April.

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