Introduction
As we welcome the heat season in Antigua and Barbuda, it’s crucial to be mindful of the potential harm that excessive heat can pose, especially to the most vulnerable members of our community. From soaring temperatures to intense sun rays, the summer months require us to take proactive steps to stay safe and healthy while enjoying the beauty of our island paradise. Join us as we explore the importance of heat safety and how to protect ourselves and our loved ones during the heat season.
A Brief Overview of Our Heat Season
Our heat season runs officially from May 1 to October 31, which is also true for most of the Caribbean. During this time, the sun is at a high angle in the sky which leads to more direct and intense solar radiation, resulting in increased heat at the Earth’s surface. The existence of more moisture in the atmosphere also explains the greater heat at this time of the year as the water vapour serves as a natural greenhouse gas trapping the heat from the sun.
The most intense part of the heat season is July-September. During this time of the year, the temperature often reaches or exceeds 33 °C (91 °F) and peaks near 38 °C (100 °F). The heat can be particularly intense for the wind-sheltered parts of the islands and during calm or light winds and humid days.
The measured temperature is only one side of the story regarding the heat. The other side is the heat index or feels-like temperature. This is the temperature is a measure of how hot it feels to the human body when relative humidity is factored in with the actual air temperature. In other words, it quantifies the combined effects of heat and humidity on our perception of temperature. During the heat season, the heat index temperature is frequently over 42 °C (108 °F) and peaks near 54 °C (129 °F).
Forecast for the 2024 Heat Season
The 2024 heat season is expected to be much warmer than usual, perhaps reaching record-breaking levels. From a confidence standpoint, models surveyed indicate at least an 80 percent chance of the heat season being warmer than usual with daily max temperatures more frequently than usual exceeding 35 °C (95 °F). With such temperatures, the heat index will exceed 45 °C (113 °F) more than usual.
Why So Hot?
The potential record-breaking heat for the season will be due to the forecast much warmer than normal sea surface temperature across the tropical North Atlantic (TNA) Ocean and the wide North Atlantic.
Contributing to the warmer-than-usual heat season are also climate change and the unintended consequences of bills such as the United States Clean Air Act. However, there are uncertainties; there is the x-factor of Saharan Dust that we cannot account for beyond days.
Understanding the Risks
The heat season in Antigua and Barbuda brings with it the risk of heat-related illnesses, which can range from mild heat exhaustion to life-threatening heatstroke. Vulnerable populations such as the elderly, young children, pregnant women, and individuals with chronic health conditions are particularly susceptible to the effects of extreme heat. It’s essential to recognize the signs of heat-related illnesses, including dizziness, nausea, headaches, rapid heartbeat, and confusion, and take immediate action if symptoms occur.
Protecting the Most Vulnerable
During the heat season, it’s crucial to pay special attention to the needs of the most vulnerable members of our community. Check on elderly neighbours, family members, and friends regularly, especially those living alone or without access to air conditioning. Ensure that young children and infants are kept cool and well-hydrated, and never leave them unattended in vehicles, even for a short period. Pregnant women should also take extra precautions to avoid overheating and stay hydrated throughout the day.
Staying Safe in the Summer Sun
To stay safe and healthy during the heat season, follow these essential tips:
- Stay Hydrated: Drink plenty of water throughout the day, even if you don’t feel thirsty. Avoid sugary and alcoholic beverages, as they can contribute to dehydration.
- Seek Shade: Limit exposure to direct sunlight, especially during the hottest hours of the day (10 a.m. to 4 p.m.). Seek shade under trees, umbrellas, or awnings when outdoors.
- Dress Appropriately: Wear lightweight, loose-fitting clothing made of breathable fabrics such as cotton or linen. Opt for light colours that reflect rather than absorb sunlight.
- Use Sun Protection: Apply sunscreen generously to exposed skin, including your face, neck, arms, and legs. Choose a broad-spectrum sunscreen with SPF 30 or higher and reapply every two hours or after swimming or sweating.
- Plan Outdoor Activities Wisely: Schedule outdoor activities and exercise for the early morning or late afternoon when temperatures are cooler. Take frequent breaks in shaded areas and listen to your body’s cues to avoid overheating.
- Stay Informed: Keep an eye on local weather forecasts and heat advisories issued by the Antigua and Barbuda Meteorological Service. Take appropriate precautions during periods of extreme heat and avoid outdoor activities if advised.
Conclusion
As we embrace the heat season in Antigua and Barbuda, let’s prioritize our health and safety by staying informed, vigilant, and prepared. By taking proactive steps to protect ourselves and our loved ones from the potential harm of excessive heat, we can enjoy all that our beautiful island home has to offer while staying safe in the summer sun. Here’s to a safe and enjoyable heat season ahead!
