The last month of the autumn, May, is a hot month in Ambarawa, Indonesia, with an average temperature varying between 25.4°C (77.7°F) and 30.2°C (86.4°F).

Temperature

The beginning of May records an average high-temperature of a tropical 30.2°C (86.4°F), marking a negligible difference from April's 29.7°C (85.5°F). A minor drop in temperature is observed from daytime highs in Ambarawa during the nights of May, averaging a moderately hot 25.4°C (77.7°F).

Heat index

For May, the heat index is evaluated at a torrid 37°C (98.6°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 highly critical to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
