What does the forecast hold? Drier months, increased heat expected

Residents of the Caribbean island nation of Saint Lucia are being urged to prepare for prolonged dry conditions and above-average temperatures over the closing months of 2026, as a developing El Niño pattern reshapes regional weather through the island’s traditional wet season.

Speaking at a Wednesday press briefing hosted by the Saint Lucia Water and Sewerage Company (WASCO) held at the National Workers Union Conference Room, Saint Lucia Meteorological Services Director Vigil Saltibus outlined the key risks associated with the current climate shift. El Niño, a naturally recurring ocean-atmosphere weather pattern defined by unusually warm surface temperatures across the eastern and central Pacific Ocean, is partially driving the expected deviation from typical seasonal conditions.

“El Niño typically acts to suppress rainfall during the Caribbean wet season, and the event is also linked to higher-than-average global temperatures overall,” Saltibus explained. While the large-scale pattern reduces overall precipitation, he emphasized that dangerous weather events remain possible. Localized flooding can still develop if atmospheric instability combines with enough moisture, particularly in association with passing tropical waves, tropical storms, and upper-level troughs, he warned. Residents should remain vigilant for these events even amid broader dry conditions.

El Niño events generally last between 9 and 12 months, and occur at irregular intervals of 2 to 7 years. Saint Lucia’s official wet season runs from June through November, but Saltibus’s forecast shows the most severe drought and peak heat will hit between September and November. This high-risk window aligns exactly with the peak of the annual Atlantic hurricane season, which runs from June 1 to November 30 each year.

Despite the overlapping timing, Saltibus noted that El Niño typically suppresses Atlantic hurricane activity, leading to a 2026 season forecast to be near-normal to below-normal in overall activity. Official meteorological predictions call for 8 to 14 named storms, 3 to 6 hurricanes, and 1 to 3 major hurricanes (Category 3 or higher) this season. As of early August, two named storms – Arthur and Bertha – have already formed and moved through the Atlantic basin.

In response to the forecast, both Saltibus and WASCO leadership have stressed that proactive preparedness and consistent water conservation remain top priorities for communities across Saint Lucia to mitigate the impacts of the coming dry and hot conditions.
