Weather in May
Temperature
May registers an average high-temperature of a still tropical 30.6°C (87.1°F), slightly varied from April's 31.8°C (89.2°F). Pahala Bomiriya's nights throughout May are marked by an average low temperature of 26.3°C (79.3°F), a minor drop from the day's high.Heat index
In May, the average heat index is computed to be a blistering 40°C (104°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
