Weather in May
Temperature
May's onset brings an average high-temperature of a still warm 29.5°C (85.1°F), showing a minute difference from April's 29.7°C (85.5°F). In Polémie, an average temperature of 23.3°C (73.9°F) is noted during May nights.Heat index
The heat index in May is calculated to be a sweltering 38°C (100.4°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 of high significance for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
