Weather in May
Temperature
Katugoda records an average high-temperature of a warm 29.5°C (85.1°F) as May arrives, nearly mirroring the previous month's climate. Night temperatures in May exhibit a subtle decrease, settling at an average of 26.7°C (80.1°F).Heat index
May's heat index is estimated at a very hot 36°C (96.8°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Consider that heat index readings are for situations in the shade and light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 highly critical for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

May and September, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: A maximum high daily UV index of 6 during May translates into the following directions:
Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Stay sun-safe with clothing that is both closely woven and worn loosely.
