Written on 06/04/2025

The CariCOF Climate Outlooks for June to August 2025 are now available. These include:

The following excerpt from CariCOF’s Caribbean Climate Outlook Newsletter summarizes the climate conditions and related hazards for the upcoming 3-month period June to August 2025:

“ENSO neutral conditions in the Pacific, combined with unusually warm waters around the Caribbean and, temporarily, cooler waters in the eastern Tropical North Atlantic imply:

(i) a Caribbean Heat Season with the possibility of heatwaves, gradually ramping up, but unlikely to match 2023 and 2024;

(ii) rainfall intensity and shower frequency should rise, resulting in high to extremely high potential for flooding, flash floods, cascading hazards and associated impacts;

(iii) an intense first half of the Atlantic Hurricane Season, with a likely number of named storm between three and ten in this period. Forecasts of Saharan dust intrusions only show useful skill up to one or two weeks ahead. Historically, such episodes tend to be frequent through August and tend to produce spells of hot and humid conditions with reduced air quality, all the while stifling intense shower and tropical cyclone activity.”
