The Dominican Institute of Meteorology (Indomet) has released an official three-day weather forecast, active from 6:00 a.m. Sunday, September 6, 2026, through 6:00 a.m. Tuesday, September 8, 2026, warning of significant weather shifts driven by two key atmospheric systems: a tropical wave and an upper-tropospheric trough.

On Sunday morning, early showers and thunderstorms are already projected to impact the country’s eastern and northeastern provinces, along with the entire Caribbean coastline. By Sunday afternoon, the combined influence of the tropical wave, upper trough, and local geographic effects will amplify precipitation, triggering intense localized downpours across the Dominican Republic’s interior regions. These heavy rain events will be accompanied by sudden thunderstorms and strong wind gusts. The hardest-hit inland areas are expected to include Hato Mayor, Monte Plata, Duarte, northern Azua, San Juan, Elías Piña, Dajabón, Santiago Rodríguez, southern Santiago, Monte Cristi, and surrounding adjacent communities.

For Greater Santo Domingo, which encompasses the National District, Sunday will bring scattered morning cloud cover and a chance of light showers, with sweltering hot conditions settling in by the afternoon. Across the entire country, temperatures will remain elevated, producing an oppressive heat index that poses health risks to sensitive groups. Indomet has issued public health guidance urging all residents to drink water consistently throughout the day, wear lightweight, loose-fitting, light-colored clothing, and avoid unprotected extended exposure to direct sunlight. Pregnant people, children, and older adults are flagged as particularly vulnerable to heat-related illness. Overnight minimum temperatures will stay between 24°C and 26°C, while daytime highs will reach 34°C to 36°C across most low-lying regions.

Moving into Monday, after the tropical wave passes, residual atmospheric moisture will interact with orographic wind effects and the lingering upper-level trough to drive increasing cloud development through the afternoon. Localized heavy downpours, thunderstorms, and gusty winds are forecast for provinces along the Central Mountain Range, the southeastern region, and the country’s border zone. Indomet specifically named El Seibo, Hato Mayor, San José de Ocoa, La Vega, Elías Piña, and San Juan as areas at risk for stormy conditions on Monday. Santo Domingo and the National District will see mostly isolated cloud cover with clear spells through the day.

By Tuesday, the upper trough is projected to shift away from the Dominican Republic, leading to reduced, more isolated rainfall of lower intensity across the southeast, Central Mountain Range, border zone, and northwest. Any precipitation on Tuesday will be confined to the afternoon, with only isolated thunderstorms and wind gusts expected to clear by early evening. A new atmospheric feature will arrive Tuesday: a moderate plume of Saharan dust moving into the region. Greater Santo Domingo will see occasional cloud cover with only isolated light showers on Tuesday.

Indomet also released detailed province-by-province forecasts for the three-day period:

A powerful natural climate event that shapes global weather patterns is set to strengthen dramatically in the coming months and hold its influence across the planet at least until February 2025, according to forecasts from the World Meteorological Organization (WMO). This event, known as El Niño, will reshape global rainfall and temperature distributions, driving far-reaching effects on ecosystems, food systems, and communities worldwide. To understand what this phenomenon means, we break down its origins, mechanics, projected impacts, and the hopeful outlook for preparedness.

El Niño is the warm phase of the El Niño-Southern Oscillation (ENSO), a naturally recurring climate cycle centered on the equatorial Pacific Ocean. Occurring every two to seven years, the event is defined by above-average sea surface temperatures across the central and eastern equatorial Pacific, paired with corresponding shifts in atmospheric conditions above the ocean.

The current El Niño draws much of its strength from already record-high ocean temperatures across the tropical Pacific, which lines the coasts of Ecuador, Colombia, and Peru on its Latin American margin. Forecasters project it will peak in intensity by the end of 2024, but its residual climate impacts will ripple through global weather systems well into 2025.

The ENSO cycle has two distinct extreme phases: the warm El Niño and the cool La Niña, differentiated by sea surface temperature anomalies in the equatorial Pacific. While an El Niño event typically lasts up to 18 months, La Niña events can extend for as long as three years. The name “El Niño”, meaning “the Little Boy” or “Christ Child” in Spanish, dates back centuries to regional sailors and fishermen along the Pacific coast of South America, who first noted that a unusually warm current would arrive around Christmas and reduce fish catches, leading them to name the phenomenon after the infant Jesus.

One of the most significant global effects of El Niño is its tendency to push up average global temperatures, with warming impacts often becoming fully visible a year after the event begins. For example, the 2023-2024 El Niño, combined with long-term human-caused climate change, pushed 2024 to become the warmest year ever recorded on Earth. This year, scientists have sounded particular alarm over extreme ocean warming linked to the current event: subsurface sea temperatures in key parts of the Pacific have jumped more than 8 degrees above the long-term average.

El Niño rewires rainfall patterns across every continent. It typically brings above-average rainfall and elevated flood risk to parts of South America, East Africa, and the southern United States. On the flip side, it drives severe drought across eastern and northern Australia, Indonesia, southern Africa, and much of southern Asia, while also suppressing hurricane formation in the Atlantic Ocean.

These climate shifts translate directly to tangible social and economic harms. The most widespread critical impact is reduced agricultural output, which erodes food access for vulnerable communities and pushes up food prices globally. In 2024, disrupted rainfall has already triggered devastating drought and water scarcity across parts of Central America, wiping out corn crops and threatening the livelihoods of thousands of small-scale farming families. In India, August monsoon rains fell far below seasonal averages, and forecasts point to continued dry conditions into September, putting additional strain on the country’s agricultural sector.

Despite the projected strong intensity of the 2024-2025 El Niño, WMO Secretary-General Celeste Saulo emphasized in a recent briefing that a strong event does not equal inevitable catastrophe. “It does not mean there is a 100% probability of a flood, a drought, or even a heat wave occurring in a particular country,” Saulo noted. Importantly, she added, the global community already holds the scientific knowledge and practical tools needed to prevent El Niño-related hazards from escalating into full-blown humanitarian crises.

Across the Caribbean’s most popular coastal tourist hubs, a growing environmental crisis is delivering a significant blow to the region’s $30 billion a year tourism industry, with iconic destinations already seeing sharp drops in visitor numbers. In Mexico’s top Caribbean resort areas of Cancún and the Riviera Maya, massive accumulations of foul-smelling sargassum algae have smothered miles of golden beaches and shorelines, driving the steep decline in tourist arrivals that has local authorities and business owners scrambling to respond. While rising security concerns have also contributed to falling visitor counts in these world-famous getaways, multiple sector insiders confirm that the invasive seaweed outbreak remains by far the biggest driver of the downturn, a conclusion rarely shared publicly despite widespread private agreement.

The sargassum plague is not isolated to Mexico’s Caribbean coast. It has spread rapidly across the entire region, leaving few popular tourist destinations untouched, including the Dominican Republic’s most visited coastal areas. Year after year, the scale of the outbreak has grown worse, with almost every beach in the country’s eastern region now plagued by the destructive algae – even the normally pristine shorelines of Bayahibe and its surrounding communities have not been spared. For most travelers planning trips to the island, however, the distinction between affected and unaffected areas is rarely clear: many visitors write off the entire Dominican Republic as a tourist destination once they see images of sargassum-covered coastlines, even if their intended destination remains algae-free.

Frank Rainieri, one of the most respected and moderate leaders of the Dominican Republic’s tourism sector, has recently issued an urgent call to action, warning that the country cannot afford to delay a coordinated response to the crisis. Rainieri stresses that tackling the sargassum problem is just as critical as resolving ongoing water supply shortages that have plagued the Punta Cana and Bávaro regions, another top issue facing the island’s tourism industry. To date, the Dominican government has moved slowly to roll out a comprehensive national action plan to address the outbreak, and Rainieri warns that further inaction carries severe consequences. For a small island nation that relies heavily on tourism to drive its national economy, even a short-term drop in visitor arrivals can create long-lasting economic damage. While experts acknowledge that eradicating sargassum entirely is a complex, long-term challenge, the example of Mexico’s already declining tourism numbers makes clear that implementing preventative mitigation measures as quickly as possible is essential to avoiding a similar crisis for the Dominican Republic.
