May, the last month of the pre-monsoon summer in
Mangaluru, is another tropical month, with temperature in the range of an average low of 25.1°C (77.2°F) and an average high of 33.3°C (91.9°F).
Temperature
The advent of May denotes an average high-temperature of a still hot 33.3°C (91.9°F), subtly different from
April's 34°C (93.2°F). In May, Mangaluru experiences a temperature dip to an average of 25.1°C (77.2°F) at night.
Heat index
During May, the heat index is appraised at a burning hot 45°C (113°F).
Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

UV index
The months with the highest UV index are
February through
September, with an average maximum UV index of 12. A UV Index value of 11, and more, symbolizes an extreme threat to health from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: The UV index of 12 in May translates into these instructions:
Employ every crucial safety step. Those with fair skin could experience burns in a matter of minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. To cut down UV radiation exposure by about half, sport a wide-brim hat. After every outdoor workout or swim, liberally apply and frequently reapply a broad-spectrum SPF 30+ sunscreen. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
