May weather forecast
Nintavur, Sri Lanka

The last month of the spring, May, is another tropical month in Nintavur, Sri Lanka, with an average temperature ranging between min 26.6°C (79.9°F) and max 32.7°C (90.9°F).

Temperature

With the advent of May, Nintavur's high-temperatures adjust to a still tropical 32.7°C (90.9°F), closely aligning with the preceding month. An average temperature of 26.6°C (79.9°F) is recorded during the nights in May.

Heat index

The heat index in May is estimated at a blisteringly hot 44°C (111.2°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
