Temperature

The beginning of April records an average high-temperature of a still tropical 31.8°C (89.2°F), marking a negligible difference from March's 30.1°C (86.2°F). During the month of April, the temperature falls to an average of 25.9°C (78.6°F).

Heat index

The heat index for April is evaluated at a blistering 42°C (107.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat. Warning! Sand and water reflections boost the intensity of UV exposure.
