Weather in May
Temperature
May registers an average high-temperature of a still tropical 30.8°C (87.4°F), slightly varied from April's 32°C (89.6°F). Ellakkala registers a small shift from peak daytime temperatures, with a consistent average low-temperature of 26.4°C (79.5°F) during May.Heat index
During May, the heat index is evaluated at a blistering 40°C (104°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Consider that heat index readings are for situations in the shade and light wind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
