Temperature

The arrival of May witnesses a small shift in the average high-temperature, moving from a moderately hot 29.3°C (84.7°F) in April to a tropical 32.6°C (90.7°F). Throughout May, the average low-temperature dips to a warm 24.2°C (75.6°F).

Heat index

Throughout May, the heat index is calculated to be a life-threatening hot 45°C (113°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Take into consideration that the heat index values are calculated for shade and light wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Note: In May, a regular UV index of 7 translates into these guidelines:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
