Prolonged Heatwave Raises Health Concerns for Both Humans and Marine Ecosystems
The VI Territorial Emergency Management Agency (VITEMA) has sounded the alarm about persistent elevated temperatures expected to dominate the region till October. Such sweltering conditions can trigger heat-related health complications, like heat exhaustion and heat strokes, for the territory’s residents.
Recent data shared by VITEMA’s Executive Director, Daryl Jaschen, during a Government House Press Briefing, revealed that St. Croix has shattered daily temperature records consecutively over the past twelve days. The gravity of the situation is further underscored by a heat advisory from the National Weather Service in Puerto Rico. As per Jaschen, this advisory is indicative of “an impending period of intensified heat, wherein the synergy of extreme temperatures and heightened humidity could result in potential heat ailments.”
To combat these adverse conditions, the public is being urged to ramp up fluid intake and, when feasible, find solace in air-conditioned environments. Moreover, residents are counseled to minimize direct exposure to the sun and to make periodic rest intervals a routine, especially for those whose jobs demand outdoor presence.
Jaschen emphasizes the need for vigilance among supervisors, referencing guidelines set by the Occupational Safety and Health Administration (OSHA) to mitigate the risk of heat-induced illnesses for outdoor workers. “For anyone overseeing staff, it’s crucial to safeguard their well-being,” asserted Jaschen.
Furthermore, engaging in physically demanding tasks is best reserved for cooler periods, such as dawn or dusk. Jaschen also suggests that donning attire that’s light-hued and not constricting can offer some relief.
The Caribbean Climate Outlook Forum’s (CariCOF) Heat Prognosis for September 2023 to February 2024 identifies August and September as the peak heat months, with September slated to be exceptionally harsh. These scorching temperatures aren’t just perilous for humans but have drastic implications for marine life too. The Caribbean Sea and Northern Atlantic have recorded unprecedented sea surface temperatures, instigating heat-induced distress to coral reefs throughout the Caribbean. This has precipitated a surge in coral bleaching, a phenomenon that jeopardizes the reefs. Notably, these reefs play a pivotal role in shielding several islands from the brunt of hurricane-induced sea surges and other challenging marine scenarios.
Derek Manzello, the Coral Reef Watch Coordinator for the National Oceanic and Atmospheric Administration (NOAA), offers some insight into the matter. He indicates that while corals have the capacity for recovery post mild bleaching events, protracted or intense heat distress elevates their mortality risk. Moreover, even those corals that manage to recover display diminished growth and reproductive capacities, with heightened susceptibility to diseases for up to four years post-recovery.
To summarize, the intense heat poses significant health threats, both to humans and marine organisms, with the hope of relief only in sight by next month.

The Science Behind USVI’s Tropical Climate
The U.S. Virgin Islands is known for its stunning beaches, lush landscapes, and year-round sunshine, making it a prime destination for tourists seeking a tropical paradise. But what makes the USVI’s climate so unique? To understand the science behind this region’s tropical weather, we must explore a combination of geographical location, ocean currents, and atmospheric conditions that shape the islands’ environment.
Location and Latitude: The Tropical Zone
The USVI is located in the Caribbean, just north of the equator, which places the islands within the tropical zone. This location is significant because the sun’s rays are more direct here than in temperate regions, leading to consistently warm temperatures throughout the year. The islands sit between 17°N and 18°N latitude, which means they experience minimal variation in daylight hours compared to regions farther north or south.
The average temperature in the USVI ranges from 77°F (25°C) to 88°F (31°C) depending on the time of year. Even during what is considered the “winter” season, temperatures remain warm, allowing for comfortable conditions year-round. The proximity to the equator also means that the islands do not experience extreme seasons like those found in temperate climates.
Ocean Currents: A Natural Climate Moderator
The surrounding waters of the Caribbean Sea and the Atlantic Ocean play a critical role in moderating the climate of the USVI. Warm ocean currents, such as the Gulf Stream, help to maintain consistent temperatures by transferring heat from the tropics to higher latitudes. These currents also create a buffer against drastic changes in temperature, making the climate relatively stable.
The warm waters around the USVI contribute to the high humidity levels often experienced on the islands. This humidity, combined with the tropical heat, can make the air feel warmer than the actual temperature. However, the trade winds that blow across the islands help to alleviate some of the discomfort by providing a cooling breeze, especially along coastal areas.
Trade Winds: The Islands’ Natural Air Conditioning
Trade winds are another key component in shaping the tropical climate of the USVI. These steady, easterly winds blow from the northeast and provide a natural cooling effect, especially during the hotter months. The trade winds are a result of global atmospheric circulation patterns caused by the earth’s rotation and the heating of the equator.
These winds not only cool the islands but also contribute to the relatively stable weather patterns. While hurricanes and tropical storms are a concern during the Atlantic hurricane season, the USVI often experiences more moderate weather due to the trade winds’ influence. The winds help to steer tropical storms and hurricanes away or reduce their intensity before they reach the islands.
Rainfall Patterns: Wet and Dry Seasons
While the USVI enjoys sunny days most of the year, it is also subject to a tropical climate’s typical rainfall patterns. The islands experience two distinct seasons: a wet season and a dry season. The wet season typically runs from June to November, coinciding with the Atlantic hurricane season, while the dry season occurs from December to May.
During the wet season, the islands receive the majority of their annual rainfall, which averages around 40 inches per year. The showers are often short but intense, followed by sunshine. The dry season, on the other hand, sees less frequent rain, and the lush greenery of the islands can become more arid. Despite this, the trade winds continue to bring moisture, keeping the islands relatively humid throughout the year.
The Impact of Climate Change
In recent years, the effects of climate change have become increasingly evident in the Caribbean, including the USVI. Rising sea temperatures, more intense hurricanes, and changing rainfall patterns are some of the consequences that scientists have observed. As the planet warms, the frequency and intensity of extreme weather events are expected to increase, posing challenges to the islands’ infrastructure and ecosystems.
Local initiatives are being taken to address these issues, such as developing more resilient infrastructure and protecting the islands’ natural resources. Understanding the science behind the USVI’s tropical climate can help in creating solutions that preserve the islands’ natural beauty and protect them from the impacts of climate change.
The tropical climate of the USVI is a result of its prime location, the influence of ocean currents, trade winds, and its proximity to the equator. This combination creates a paradise for residents and visitors alike, with warm temperatures, refreshing breezes, and abundant sunshine. However, the increasing impacts of climate change underscore the importance of preserving the natural environment that makes the USVI so unique. By understanding the science behind the islands’ climate, both residents and tourists can appreciate the delicate balance that sustains this tropical haven.

Weather Impact on Agriculture in USVI
The agricultural sector in the U.S. Virgin Islands has long been shaped by the region’s tropical climate. Weather plays a critical role in determining the success or failure of crops and livestock, making it a central concern for local farmers. With the increasing unpredictability of climate patterns due to global warming, understanding how weather impacts agriculture in the USVI is essential to ensuring food security and sustainable farming practices.
The Role of Climate in USVI Agriculture
The USVI enjoys a tropical climate, characterized by warm temperatures year-round, with minimal seasonal variation. Rainfall patterns are less predictable, often fluctuating between periods of drought and heavy rainfall. These extremes pose a significant challenge to agriculture, as farmers must manage crops and livestock under constantly changing conditions.
Drought, in particular, has been a recurring issue in the USVI. The islands experience extended dry spells, especially during the late winter and early spring, which can severely affect crop yields. Water shortages make it difficult for farmers to irrigate their fields, leading to stunted growth and lower production. While the USVI does have water catchment systems in place, the reliance on natural rainfall for most crops makes drought a persistent threat.
Impact of Heavy Rainfall and Storms
On the other hand, periods of excessive rainfall can also have negative consequences. Heavy rains can lead to soil erosion, nutrient depletion, and waterlogging, all of which can harm crops. Tropical storms and hurricanes, which occur more frequently during the Atlantic hurricane season from June to November, bring additional risks. The strong winds and heavy rains associated with these storms can damage crops, uproot trees, and disrupt farming infrastructure.
For livestock farmers, heavy rains and storms can lead to increased risks of disease, as wet conditions create ideal breeding grounds for parasites and bacteria. Hurricanes, in particular, are a growing concern for farmers in the USVI, as these powerful storms can devastate entire farms, leading to substantial economic losses. Infrastructure, including barns, fences, and water catchment systems, often needs to be repaired or rebuilt after severe weather events.
Climate Change and Its Long-Term Effects
The increasing frequency and intensity of extreme weather events due to climate change are further exacerbating these challenges. According to climate projections, the USVI is likely to experience more prolonged periods of drought and more intense storms in the coming decades. Rising sea levels also pose a long-term threat to low-lying agricultural areas, increasing the salinity of soil and reducing its fertility.
Local farmers have already begun to see the impacts of these changes, with more frequent crop failures and livestock health issues. To combat this, many are turning to sustainable practices, such as crop diversification, water conservation techniques, and the use of climate-resistant crops. However, the financial and technical support needed to implement these strategies remains a barrier for many small-scale farmers in the region.
Solutions and Adaptation Strategies
Adapting to the changing weather patterns is essential for the future of agriculture in the USVI. One key solution is improving water management systems. Investing in rainwater harvesting, drip irrigation, and more efficient water storage systems can help farmers maintain crop production during dry periods. The USVI government and agricultural organizations have been promoting these practices, but wider adoption is necessary to make a significant impact.
Additionally, crop diversification is another important strategy for mitigating the risks associated with extreme weather. By planting a variety of crops, farmers can spread their risk and improve their chances of at least partial success during unfavorable conditions. Furthermore, introducing drought-resistant and flood-tolerant crop varieties can help farmers better withstand the challenges posed by changing weather patterns.
Research into climate-smart agriculture is also essential. Local universities, government agencies, and international organizations can collaborate to develop farming techniques that are better suited to the USVI’s unique climate. This could involve developing new crop varieties or researching alternative farming methods, such as hydroponics or vertical farming, which are less dependent on weather conditions.
Weather will always play a critical role in agriculture in the USVI, but the growing impact of climate change makes it even more important for farmers to adapt. The future of the islands’ agriculture depends on their ability to implement sustainable farming practices and manage the risks posed by extreme weather. By investing in water management, crop diversification, and climate-resilient farming techniques, the USVI can safeguard its agricultural sector against the unpredictable weather patterns that are becoming more common in the region.
This approach will not only help ensure food security for the islands but also support the local economy and preserve the livelihoods of the farmers who depend on the land.
