The Caribbean Climate Outlook Forum has forecasted that drought and intense heat will persist across the region through December 2026. A strong El Niño event is expected to accelerate these trends and trigger an earlier-than-normal start to the 2027 heat season.
Why it matters
A very strong El Niño event and warm North Atlantic surface temperatures are driving these climate patterns, which pose significant risks to water security and public health. Saharan air intrusions are further complicating the situation by elevating temperatures and degrading air quality across the Caribbean islands.
Short-term drought was confirmed across 11 nations including Antigua, Cuba, and Puerto Rico as of September 1, 2026. Drought conditions are projected to expand and intensify across the Caribbean through May 2027.
The players
Caribbean Climate Outlook Forum
This organization monitors regional climate patterns and issues seasonal forecasts for Caribbean nations.
The details
Weakened trade winds across the tropical Pacific are causing warm surface water to flow eastward, disrupting seasonal weather patterns. These conditions, combined with dusty Saharan air intrusions that inhibit tropical cyclone activity, are sustaining the current heat and lack of rainfall.
Timeline
September 1, 2026: Short-term drought status assessed in Caribbean islands.
October 2026: Humid heat peaks in the Guianas.
October-December 2026: Drought and heat impacts projected across region.
January-March 2027: Progression to dry season peak.
May 2027: Potential for growing cascading economic impacts.
Seasonal Patterns
The projected early onset of the 2027 Heat Season represents a significant shift from historical climate records for the region. This trend follows a pattern set by the 2027 Heat Season, marking a shift toward more frequent and prolonged extreme heat events in the Caribbean basin.
Residents should prepare for potential water restrictions and increased health risks due to sustained high temperatures. Local authorities are expected to manage infrastructure vulnerabilities as drought conditions worsen over the coming months.
The takeaway
The sustained drought and heat forecast highlights the importance of proactive water management for Caribbean communities. Individuals should monitor local updates to mitigate the impacts of an extended dry season and early-onset heat.
