Temperature

May proves to be the warmest month, recording an average peak temperature of 33.3°C (91.9°F) and a minimum temperature of 26.4°C (79.5°F).

Heat index

For most parts of May, the heat index is computed to be a life-threatening hot 45°C (113°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Heat index evaluations are typically in the context of light winds and shaded environments. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

UV index

February through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: An average maximum UV index of 7 in May leads to these recommendations:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
