Haiti Climate – June 2026 Update
Top 5 Cities: Port-au-Prince, Cap-Haïtien, Delmas, Port-de-Paix, and Carrefour
This month in numbers
Haiti experienced its 5th warmest June on record in 2026, with an average temperature of 27°C, marking an anomaly of +1.4°C compared to the 1961–1990 baseline. The three-month period from April to June 2026 also ranked as the 5th warmest on record, with an average temperature of 25.95°C, an anomaly of +1.2°C. Globally, June 2026 was the 3rd warmest June for land temperatures, and the April-June period was the 2nd warmest on record for global land temperatures.
What changed
Haiti's consistently above-average temperatures this month and over the past three months align with a long-term warming trend for the nation, which has seen an increase of +1.11°C compared to the 1961–1990 baseline. The country's warmest year on record was 2025, with an average temperature of 25.93°C. Haiti's June 2026 temperature anomaly of +1.40°C places it 96th out of 234 regions globally, while its three-month anomaly of +1.21°C ranks it 154th.
What’s driving change?
The persistent above-average temperatures in Haiti are influenced by the ongoing El Niño event, which is currently in a weak phase but is expected to strengthen into the Northern Hemisphere winter 2026-27. El Niño typically leads to drier conditions in the Caribbean and Atlantic basin, and indeed, Haiti has experienced below-average rainfall for the second consecutive month in June, with deficits exceeding 55 percent of the usual average in many areas, and locally over 70 percent in the Southeast and West. This further exacerbates warming by reducing evaporative cooling. Additionally, a heatwave affected Haiti in late June, with temperatures reaching up to 38°C. The Atlantic hurricane season officially began on June 1st, and while NOAA forecasts a below-normal season, a single hurricane can still cause significant damage. Haiti also experienced heavy rains and flooding in early June, which tragically resulted in the death of an 11-year-old girl in the Pacot area due to a wall collapse.
Looking ahead
The seasonal forecast for July-September 2026 indicates a continuation of below-normal rainfall across Haiti, with a higher likelihood of below-normal conditions in the southern Grande-Anse, Sud, Nippes, western Sud-Est, and southwestern Ouest departments. Conversely, above-normal mean temperatures are highly probable for the northern, western, and most of the southern regions during this period.

Shifting Seasons
Wet / dry seasonsKöppen Am · TropicalHaiti doesn't have a warm/cold cycle - its monthly temperature range is only 3.5°C across the year - but it does have a strong wet/dry cycle (the wettest month gets 5× as much rain as the driest). So we track how the wet season has shifted instead.

FAQs
FAQs
How is the climate in Haiti changing?
Haiti 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 Haiti come from?
Climate data for Haiti 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 Haiti climate data cover?
The Haiti climate profile covers Port-au-Prince, Cap-Haïtien, Delmas, Port-de-Paix and surrounding areas. Temperature, rainfall and emissions data for Haiti
How often is the Haiti climate update refreshed?
The Haiti 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.
