May weather forecast
Brebes, Indonesia

The last month of the autumn, May, is also a moderately hot month in Brebes, Indonesia, with an average temperature fluctuating between 21.8°C (71.2°F) and 28.8°C (83.8°F).

Temperature

The average high-temperature, a still warm 28.8°C (83.8°F) in May, matches the temperature recorded in April. In Brebes, an average low-temperature of 21.8°C (71.2°F) is recorded during May nights.

Heat index

The heat index value during May is evaluated at a sweltering 35°C (95°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
