Weather in April

April in Rosario, Philippines, is a tropical spring month, with an average temperature ranging between max 31.9°C (89.4°F) and min 23.8°C (74.8°F).

Temperature

As March transitions into April, the average high-temperature rests at a tropical 31.9°C (89.4°F), maintaining a close resemblance to the previous month. An average low-temperature of 23.8°C (74.8°F) is observed during April nights.

Heat index

For most parts of April, the heat index is evaluated at a blisteringly hot 42°C (107.6°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Humidity

With an average relative humidity of 75%, April is the least humid month.

UV index

February through October, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for the ordinary person.
Note: In April, the maximum UV index of 7 transforms into these recommendations:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
