Weather in April
Temperature
The advent of April sees the average high-temperature at a tropical 30.6°C (87.1°F), subtly shifted from March's 28°C (82.4°F). In April, the recorded average low-temperature is a pleasant 21°C (69.8°F).Heat index
April's mean heat index is evaluated at a sweltering 37°C (98.6°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index guidelines indicate values are for light wind scenarios and shaded regions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for average individuals.Note: The daily maximum UV index of 7 in April interprets into the following advice:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
