Temperature

A negligible change is observed in Kalijaten's average high-temperature at the start of April, equating it to March's temperature. Kalijaten marks an average drop to a warm 25.6°C (78.1°F) during nighttime in April, following the high of the day.

Heat index

In April, the heat index is evaluated at a torrid 38°C (100.4°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

In April, the average relative humidity is 76%.

UV index

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 are January through December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for ordinary individuals.
Note: The maximum UV index of 7 during April translates into these guidelines:
Inhibit overexposure. Warding off sun damage is of utmost importance. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
