Weather in May

May magnifies the weather changes that initiated in April with a maximum recorded rainfall of 91mm (3.58"). The temperature takes a slight dip compared to April, but the days become longer and the city experiences significant warmth. The added moisture in the atmosphere increases the cloud cover and decreases the daily hours of sunshine. Consequently, May signals a transition towards a more pronounced wet season, setting the stage for the extensive rain showers in June.

Temperature

May's beginning signals an average high-temperature of a still sweltering 36.4°C (97.5°F), barely different from April's 38.3°C (100.9°F). Nighttime temperatures in May average to a warm 25°C (77°F).

Heat index

The heat index in May is calculated to be a burning hot 47°C (116.6°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Note: In May, the average maximum UV index of 7 translates into the following recommendations:
Prevent overexposure. Protection from the sun's harmful effects is needed. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
