Temperature

April's presence marks an average high-temperature of a still warm 29.9°C (85.8°F), subtly varied from March's 29.4°C (84.9°F). Lawas's nights in April cool down to an average low-temperature of 22.5°C (72.5°F).

Heat index

For most parts of April, the heat index is evaluated at a sweltering 39°C (102.2°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Humidity

The months with the highest humidity are January, March, April and December, with an average relative humidity of 84%.

UV index

The months with the highest UV index are February through April, July through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for the average person.
Note: During April, 7 as the daily maximum UV index converts into the following advice:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
