Temperature

Dumara's transition from April to May introduces an average high-temperature of a still tropical 30.1°C (86.2°F), marking an insignificant variation from the 30.3°C (86.5°F). In the month of May, Dumara's average low-temperature falls to a warm 23.1°C (73.6°F).

Heat index

The heat index for May is evaluated at a fiery hot 39°C (102.2°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

UV index

The months with the highest UV index in Dumara are January through May, September through December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.
Note: In May, the maximum UV index of 7 transforms into these recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
