Weather in May
Temperature
May's onset records an average high-temperature of a still moderately hot 29.9°C (85.8°F), a near match to April's 29.6°C (85.3°F). Throughout May, an average low-temperature of 22.2°C (72°F) is expected.Heat index
During May, the heat index is appraised at a torrid 37°C (98.6°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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 achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
