Dominican Republic Climate – June 2026 Update
Top 5 Cities: Santo Domingo, Santiago, La Romana, San Pedro de Macorís, and San Cristóbal
This month in numbers
June 2026 saw the Dominican Republic experience its 4th warmest June on record, with an average temperature of 25.99°C, a significant 1.1°C above the 1961–1990 baseline. This continues a trend of elevated temperatures, as the April–June 2026 period also ranked as the 5th warmest on record, with an anomaly of +1.1°C. Globally, June 2026 was the 3rd warmest June for land temperatures, and the April–June period was the 2nd warmest for global land temperatures.
What changed
The Dominican Republic has been experiencing a sustained period of warmer-than-average conditions. The latest full year, 2025, was the warmest on record for the country, at 25.32°C. This warming trend is consistent with the broader global picture, where land temperatures are also significantly above average. The country's June anomaly of +1.11°C placed it 129th out of 234 regions globally for the latest month's temperature anomaly, while its 3-month anomaly of +1.06°C ranked it 171st.
What’s driving change?
The prevailing El Niño phenomenon is a significant driver of the current warming trend and associated weather patterns in the Dominican Republic. NOAA confirmed El Niño's establishment in the equatorial Pacific in June 2026, with a high probability of it continuing and potentially intensifying to a "very strong" category by late 2026 and early 2027. El Niño typically leads to prolonged drought conditions and above-average temperatures in the Caribbean region, while also suppressing Atlantic hurricane activity. Indeed, June 2026 saw record-breaking maximum temperatures in several locations across the country, including Sabaneta at 39.9°C and Santo Domingo East at 36.6°C. The Dominican Republic has activated its 2026 Cyclone Season Contingency Plan in response to these forecasts, preparing for both reduced storm activity and the broader effects of El Niño, including extreme heat and drought conditions. More information on ENSO can be found at ENSO.
Looking ahead
Forecasts suggest that intense heat will persist across much of the Dominican Republic for the coming weeks, particularly in the northwest, north, and southwest regions, with maximum temperatures potentially reaching between 35°C and 39°C.

Shifting Seasons
Wet / dry seasonsKöppen Af · TropicalDominican Republic doesn't have a warm/cold cycle - its monthly temperature range is only 3.6°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 3× as much rain as the driest). So we track how the wet season has shifted instead.

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