Weather in April
Temperature
The advent of April brings an average high-temperature of a still warm 27.7°C (81.9°F), almost identical to the preceding month. April introduces a small decrease to a nighttime average of 25.3°C (77.5°F).Heat index
Throughout April, the heat index is calculated to be a tropical 31°C (87.8°F). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.

A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.Note: In April, a regular UV index of 7 translates into these guidelines:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
