Heat index

The heat index value for April is evaluated at a very hot 38°C (100.4°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Realize that the values for the heat index are set for shaded places and light winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Humidity

The months with the lowest humidity are March and April, with an average relative humidity of 72%.

A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for ordinary individuals.
Note: In April, an average UV index of 7 transforms into the following instructions:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes. Be wary! Reflections from sand and water make UV radiation more intense.
