Temperature

The transition from April to May brings an average high-temperature of a still moderately hot 28.8°C (83.8°F), barely different from April's 28.7°C (83.7°F). Nighttime temperature dips to a mean of 22.3°C (72.1°F) during May.

Heat index

The heat index value during May is estimated at a sweltering 37°C (98.6°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
