Weather in April
Temperature
As April takes hold, the average high-temperature is a still warm 29.8°C (85.6°F), nearly mirroring that of the previous month. Throughout April, Kalawisan records a steady low-temperature average of 25.3°C (77.5°F), a minor decrease from its daytime counterpart.Heat index
The heat index in April is estimated at a very hot 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

The months with the highest UV index are January through December, with an average maximum UV index of 7. The months with the lowest UV index in Kalawisan are January through December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for the ordinary person.Note: The UV index of 7 during April leads to these advisories:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
