As the anticipation of the monsoons builds, May brings an obvious surge in rainfall, with levels rising considerably to 110mm (4.33").

The increasing rainfall adds a sense of freshness to the air, painting the city in vibrant shades of green.

Temperature

May's onset in Bengaluru records a minor alteration in the average high-temperature to a tropical 33.3°C (91.9°F) from April's 35.8°C (96.4°F). An average low-temperature of 21.5°C (70.7°F) is noted during the nights in May.

Heat index

For May, the heat index is calculated to be an extremely hot 40°C (104°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Execute every important safeguard, as unprotected skin and eyes could burn within moments. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Post an outdoor workout or swimming, a broad-spectrum SPF 30+ sunscreen should be applied generously and frequently.
