As we move through the latter part of the 2026 wet season, the latest Caribbean Climate Outlook from the Caribbean Institute for Meteorology and Hydrology (CIMH) points to conditions that could have implications for our water resources.
From September to November, the region is expected to experience unusually warm temperatures, while rainfall across much of the Antilles is forecast to be usual or below usual. Drought conditions may also develop or intensify in some areas.
At the same time, fewer wet days do not eliminate the risk of intense rainfall, flash flooding and related impacts.
NAWASA encourages consumers to remain climate aware and continue practising responsible water use. Climate variability affects the availability of the water we depend on, and every effort to conserve counts.

The latest Caribbean Climate Outlook Newsletter provides the forecast for rainfall, temperature, drought and other climate conditions across the Caribbean for September to November 2026.
๐ Three key highlights:
๐ก๏ธ Unusually warm temperatures are forecast across the Caribbean, with recurrent episodes of excessive humid heat and heatwaves expected through the period.
๐ง๏ธ Rainfall totals are likely to be usual or below usual across most of the Antilles, the Northwest Bahamas and coastal Guyana. Despite fewer wet days and wet spells, the potential for flooding, flash floods and cascading impacts remains high to extremely high across much of the region.
๐พ Drought conditions are expected to expand or worsen in several areas, with agricultural, short-term and long-term drought likely to develop, continue or intensify through November.
