Temperature

The transition into May shows a subtle variation to a still tropical 31.8°C (89.2°F) from April's 32.9°C (91.2°F) in the average high-temperature. Pussella, in the month of May, anticipates a consistent average low-temperature of 23°C (73.4°F).

Heat index

May's average heat index is estimated at a blistering 42°C (107.6°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Humidity

In May, the average relative humidity is 77%.

Note: A daily high UV index of 7 in May leads to these guidelines:
Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
