Weather in May

May, the last month of the autumn in Lamongan, is another hot month, with an average temperature fluctuating between 31.2°C (88.2°F) and 23.3°C (73.9°F).

Temperature

Lamongan's average high-temperature in May is a still hot 31.2°C (88.2°F), marking an insignificant difference from the 30.6°C (87.1°F) of April. An average nighttime temperature of 23.3°C (73.9°F) is witnessed in Lamongan throughout May.

Heat index

For most parts of May, the heat index is estimated at a scorching 41°C (105.8°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Limit your exposure to direct sunlight during these hours. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
